Accessing Latvian Lats (LVL) Historical Prices with this API
If you need to backfill or audit precious metals prices in Latvian Lats (LVL) for research, accounting, or backtesting, you can do it cleanly with Metals-API’s historical endpoints and currency conversion data. In this guide, we’ll walk through accessing historical gold, silver, platinum, palladium and industrial metal prices, then converting them to LVL using the same API, so you can build robust analytics pipelines and pricing tools. You’ll see end-to-end workflows, practical caveats (units, troy ounces vs grams, timezones, caching, and market closures), and detailed explanations of what each response field means in the JSON returned by the API. We’ll also cover advanced implementation details for developers integrating LVL historical prices into trading tools, fintech applications, ERP systems, and research dashboards.
Why access metal prices in LVL? Real-world scenarios and ROI
Even though LVL is a legacy currency, many teams still require historical prices in LVL to reconcile older books, test trading strategies across currency regimes, benchmark historical hedging, or align with archival records. Typical scenarios include:
- Repricing historical jewelry or manufacturing bills of materials in LVL to match legacy ledgers.
- Normalizing long-span strategy backtests to one currency (LVL) for apples-to-apples performance comparisons, even if your live system runs in EUR or USD today.
- Building forensic dashboards for risk, audit, or M&A teams to examine exposure during LVL-era market events.
- Researching LVL-denominated commodity cycles using daily, OHLC, and fluctuation data across multi-year windows.
Metals-API provides both: (a) metal prices denominated in a base currency (by default USD); and (b) currency conversion rates. Together, you can express gold (XAU), silver (XAG), platinum (XPT), palladium (XPD), copper (XCU), aluminum (XAL), and other metals in LVL at any supported historical date range. Get started at the Metals-API Website, and check the Metals-API Supported Symbols to confirm availability for your instruments and currencies.
LVL historical pricing strategy: data flow and architecture
The core idea is straightforward:
- Query historical metal prices in the API’s default base (USD) using the Historical or Time-Series endpoints.
- Query the USD→LVL FX rate for matching dates using the Convert endpoint (amount=1) or your chosen FX approach within Metals-API.
- Compute metal price in LVL:
metal_price_LVL = metal_price_USD_per_oz × (LVL per USD) - Normalize units as needed (e.g., troy ounce to grams).
This division of responsibilities has advantages for accuracy, transparency, and maintainability. Because you pull both metal rates and FX rates from the same platform, you avoid cross-vendor timing mismatches and uncertainty around feed conventions.
Before you start: verify symbols and availability
Prior to writing code, confirm you have the necessary symbols and date coverage:
- Metals: See the up-to-date symbol list for gold (XAU), silver (XAG), platinum (XPT), palladium (XPD), copper (XCU), aluminum (XAL), nickel (XNI), zinc (XZN), and others.
- Currencies: Check whether LVL is present as a supported currency in your plan and symbol list. If not available, consider proxying through cross rates where applicable or consult the Metals-API Documentation for guidance on supported legacy currencies.
- Historical coverage: Historical metal rates are available dating back to 2019 for most series. LME symbols may go back further using the dedicated Historical LME endpoint.
Endpoint capabilities you’ll use (integrated into an LVL workflow)
Below we walk through how each feature can contribute to a complete LVL-denominated historical pricing workflow. We’ll share concrete JSON examples and how to use the response fields for your calculations.
Pull daily historical prices for a single date (Historical Rates)
Use this when you need the precise rate for one day—for example, to reconcile a specific trade date or to benchmark one transaction. Historical rates are available by appending a date (YYYY-MM-DD) to the endpoint.
Example JSON response (historical metal prices relative to USD):
{
"success": true,
"timestamp": 1789433365,
"base": "USD",
"date": "2026-09-15",
"rates": {
"XAU": 0.000485,
"XAG": 0.03825,
"XPT": 0.000915,
"XPD": 0.000748
},
"unit": "per troy ounce"
}
Key fields you’ll use:
- base: "USD" means all rates are quoted with respect to USD by default.
- date: The historical date you requested, in YYYY-MM-DD (UTC).
- rates: Object mapping each metal symbol to a rate per base currency unit (USD). For XAU=0.000485, it means 1 USD buys 0.000485 troy ounces of gold. Invert if you need USD per troy ounce (1 / 0.000485).
- unit: "per troy ounce" clarifies the unit convention.
- timestamp: Unix timestamp associated with the rate snapshot, in UTC.
To convert to LVL, you’ll multiply the USD-per-oz price by the day’s USD→LVL exchange rate. See “Combining with LVL FX” below.
Retrieve multi-day windows (Time-Series)
Use Time-Series for backfilling a chart, building a factor model, or any multi-day analysis. You can fetch a range with start_date and end_date.
Example JSON for a one-week window:
{
"success": true,
"timeseries": true,
"start_date": "2026-09-09",
"end_date": "2026-09-16",
"base": "USD",
"rates": {
"2026-09-09": {
"XAU": 0.000485,
"XAG": 0.03825,
"XPT": 0.000915
},
"2026-09-11": {
"XAU": 0.000483,
"XAG": 0.0382,
"XPT": 0.000913
},
"2026-09-16": {
"XAU": 0.000482,
"XAG": 0.03815,
"XPT": 0.000912
}
},
"unit": "per troy ounce"
}
Key fields you’ll use:
- timeseries: true confirms it’s a multi-day response.
- rates: Nested object keyed by date, each containing metal symbols and their rates vs. the base currency (USD).
- start_date/end_date: Useful for validating you received the expected window.
Once you have a daily array of rates in USD, compute LVL prices by multiplying each day’s USD-per-oz price by that day’s USD→LVL rate.
Get real-time snapshots (Latest Rates)
If you want to display a reference LVL price “now” and optionally append that to the end of your historical series, the Latest endpoint provides current rates with plan-dependent update frequency.
{
"success": true,
"timestamp": 1789519765,
"base": "USD",
"date": "2026-09-16",
"rates": {
"XAU": 0.000482,
"XAG": 0.03815,
"XPT": 0.000912,
"XPD": 0.000744,
"XCU": 0.294118,
"XAL": 0.434783,
"XNI": 0.142857,
"XZN": 0.344828
},
"unit": "per troy ounce"
}
Note the same field semantics as historical/time-series, with the addition of more symbols in a single response for convenience.
Convert amounts and fetch FX rates (Convert)
The Convert endpoint allows currency and metal conversions. The example below shows a USD→XAU conversion. To get the USD→LVL exchange rate for multiplying with metal prices, call Convert with amount=1 and from=USD, to=LVL on each date you need. Then, price_LVL = (USD-per-oz) × (LVL per USD).
{
"success": true,
"query": {
"from": "USD",
"to": "XAU",
"amount": 1000
},
"info": {
"timestamp": 1789519765,
"rate": 0.000482
},
"result": 0.482,
"unit": "troy ounces"
}
Key fields you’ll use:
- query: Inspect from, to, and amount to verify your input.
- info.rate: The rate applied at the timestamp. If you set amount=1 for USD→LVL, rate will be LVL per USD.
- result: amount × rate, which is your converted value.
- unit: Context for metals conversions (e.g., troy ounces).
Tip: When converting metals to currencies (or vice versa), clarify whether you want a quantity of metal or a money amount. For LVL pricing, keep the money amount on the FX side and the metal amount on the metals side to avoid compounding confusion.
Characterize volatility and day-over-day changes (Fluctuation)
To communicate movement over a window or to build alerts, the Fluctuation endpoint provides start and end rates with absolute and percentage changes. You can compute LVL-based fluctuations by converting both start_rate and end_rate to LVL using the corresponding USD→LVL rates for those days.
{
"success": true,
"fluctuation": true,
"start_date": "2026-09-09",
"end_date": "2026-09-16",
"base": "USD",
"rates": {
"XAU": {
"start_rate": 0.000485,
"end_rate": 0.000482,
"change": -3.0e-6,
"change_pct": -0.62
},
"XAG": {
"start_rate": 0.03825,
"end_rate": 0.03815,
"change": -0.0001,
"change_pct": -0.26
},
"XPT": {
"start_rate": 0.000915,
"end_rate": 0.000912,
"change": -3.0e-6,
"change_pct": -0.33
}
},
"unit": "per troy ounce"
}
Fields to leverage:
- start_rate/end_rate: Use these to derive LVL-equivalents for the first and last date in your window.
- change/change_pct: These are in base currency terms (USD). You can recompute LVL-specific changes if USD→LVL itself moved during the window.
Analyze daily structure with OHLC
For intraday-aware analytics that still roll up to a day-level snapshot, the OHLC endpoint returns open, high, low, and close for the requested date. Convert each to LVL if needed, using the appropriate USD→LVL conversions aligned to your timing conventions.
{
"success": true,
"timestamp": 1789519765,
"base": "USD",
"date": "2026-09-16",
"rates": {
"XAU": {
"open": 0.000485,
"high": 0.000487,
"low": 0.000481,
"close": 0.000482
},
"XAG": {
"open": 0.03825,
"high": 0.0383,
"low": 0.0381,
"close": 0.03815
},
"XPT": {
"open": 0.000915,
"high": 0.000918,
"low": 0.00091,
"close": 0.000912
}
},
"unit": "per troy ounce"
}
Practical tips:
- Define which LVL rate you use for “open” vs “close” (e.g., use a daily LVL rate aligned to UTC boundaries).
- When plotting candlesticks in LVL, convert each OHLC component the same way to keep the shapes consistent.
Quoteable prices and spreads (Bid/Ask)
When backtesting execution or modeling slippage, you may prefer bid/ask to mid. Metals-API provides bid, ask and spread per instrument.
{
"success": true,
"timestamp": 1789519765,
"base": "USD",
"date": "2026-09-16",
"rates": {
"XAU": {
"bid": 0.000481,
"ask": 0.000483,
"spread": 2.0e-6
},
"XAG": {
"bid": 0.0381,
"ask": 0.0382,
"spread": 0.0001
},
"XPT": {
"bid": 0.000911,
"ask": 0.000913,
"spread": 2.0e-6
}
},
"unit": "per troy ounce"
}
Convert bid and ask independently to LVL using the matching USD→LVL rate at your chosen time to preserve the spread structure in LVL terms.
Intraday snapshots for a single symbol (Intraday)
For advanced analytics and high-frequency monitoring, the Intraday endpoint returns more granular data for a single symbol. Use it when you need frequent updates between official daily closes. After fetching intraday USD data, apply intraday-aligned USD→LVL conversions if your use case requires LVL granularity intra-day as well.
Carat-specific gold pricing (Carat)
If you price jewelry or components by carat, the Carat endpoint provides gold rates by carat for a specified base. You can convert the resulting USD-denominated carat price to LVL via the USD→LVL rate for that date/time. Ensure you standardize the weight unit (per troy ounce) and convert to grams if your BOM or catalog requires it (1 troy ounce = 31.1034768 grams).
Range extremes in one call (Lowest/Highest) and day structure (OHLC)
The Lowest/Highest endpoint (lowest-highest/YYYY-MM-DD) lets you pull the low and high for that date per instrument. Together with OHLC, you can reconstruct range statistics and intraday variability, then express them in LVL by applying your FX conversions consistently across each referenced value.
London Metal Exchange history (Historical LME)
If your LVL analysis includes LME symbols, the Historical LME endpoint offers extended history dating back to 2008. This is useful for long-horizon research or compliance, where LVL-era coverage might be essential. As always, convert USD-denominated LME values to LVL using the date-matched USD→LVL rate from the Convert endpoint.
Step-by-step: computing LVL-denominated gold prices for a historical window
Let’s walk through a practical sequence to compute a gold time series in LVL over a date range:
- Time-series metals data: Request gold (XAU) daily values for your target window in base USD.
- Daily USD→LVL rates: For each date, fetch the USD→LVL conversion (amount=1) via the Convert endpoint.
- Multiply: price_XAU_LVL[date] = (USD_per_oz_XAU on date) × (LVL_per_USD on date).
- Optional unit conversion: To grams or kilograms if needed by your app.
- Cache and store: Persist both series to avoid re-querying and to support reproducibility.
Example curl calls
Historical rate for a single date (append a date to the endpoint). Replace YOUR_KEY and adjust the date as needed:
curl "https://metals-api.com/api/2026-09-15?access_key=YOUR_KEY&symbols=XAU,XAG,XPT,XPD"
Fetch a date range for a time series in USD:
curl "https://metals-api.com/api/timeseries?access_key=YOUR_KEY&start_date=2026-09-09&end_date=2026-09-16&symbols=XAU,XAG,XPT"
Get the USD→LVL FX rate for a given date using Convert with amount=1. Replace the date selection according to your plan and documentation:
curl "https://metals-api.com/api/convert?access_key=YOUR_KEY&from=USD&to=LVL&amount=1"
Note: Consult the Metals-API Documentation for exact query parameters and plan capabilities for date pinning on Convert and related endpoints.
Python example: build an LVL-denominated XAU series
The script below demonstrates one straightforward approach: pull a USD time series for XAU, then fetch USD→LVL for each date and compute XAU in LVL. Handle retries, caching, and pagination as needed for production systems.
import requests
from decimal import Decimal, ROUND_HALF_UP
API_BASE = "https://metals-api.com/api"
API_KEY = "YOUR_KEY"
def get_timeseries_xau_usd(start_date, end_date):
url = f"{API_BASE}/timeseries"
params = {
"access_key": API_KEY,
"start_date": start_date,
"end_date": end_date,
"symbols": "XAU"
}
r = requests.get(url, params=params, timeout=30)
r.raise_for_status()
data = r.json()
if not data.get("success", False):
raise RuntimeError(f"Timeseries error: {data}")
return data["rates"] # dict: date -> { "XAU": rate_in_oz_per_USD }
def get_usd_to_lvl_rate():
url = f"{API_BASE}/convert"
params = {
"access_key": API_KEY,
"from": "USD",
"to": "LVL",
"amount": 1
}
r = requests.get(url, params=params, timeout=15)
r.raise_for_status()
data = r.json()
if not data.get("success", False):
raise RuntimeError(f"Convert error: {data}")
return Decimal(str(data["info"]["rate"])) # LVL per USD
def usd_per_oz_from_rate(rate_oz_per_usd):
# API returns oz per USD; invert to get USD per oz
return Decimal("1") / Decimal(str(rate_oz_per_usd))
def compute_xau_in_lvl(timeseries_usd, usd_to_lvl_rate):
result = {}
for date, symmap in timeseries_usd.items():
oz_per_usd = Decimal(str(symmap["XAU"]))
usd_per_oz = usd_per_oz_from_rate(oz_per_usd)
lvl_per_oz = (usd_per_oz * usd_to_lvl_rate).quantize(Decimal("0.0001"), rounding=ROUND_HALF_UP)
result[date] = {
"XAU_LVL_per_oz": str(lvl_per_oz)
}
return result
if __name__ == "__main__":
start_date = "2026-09-09"
end_date = "2026-09-16"
# 1) Get daily XAU timeseries in USD base (values are oz per USD; invert to USD per oz)
ts_usd = get_timeseries_xau_usd(start_date, end_date)
# 2) Get LVL per USD (amount=1) via convert
usd_to_lvl = get_usd_to_lvl_rate()
# 3) Compute XAU prices in LVL per troy ounce
ts_lvl = compute_xau_in_lvl(ts_usd, usd_to_lvl)
# 4) Print or persist
for d in sorted(ts_lvl.keys()):
print(d, ts_lvl[d])
Notes:
- The API returns metals “per USD” by default (e.g., 0.000482 oz per USD). Invert to USD per oz when pricing in money terms. Then apply USD→LVL to get LVL per oz.
- If your LVL rate varies by date, fetch a date-specific USD→LVL rate for each day. Depending on your plan and documentation, you can parameterize date alignment or use a daily USD→LVL series from Metals-API.
- Use Decimal for currency-grade rounding control in production logic.
Understanding the JSON: what each field means in practice
Most Metals-API responses share a common structure with a few key fields:
- success: Boolean — always check this before processing. Non-true indicates an error you should log and handle.
- timestamp: Unix epoch seconds, UTC. Use it to synchronize across systems or to cache at a known time granularity.
- base: Typically "USD". If your plan supports changing the base, confirm its value before calculations.
- date/start_date/end_date: Use to verify the coverage and to align with FX dates before multiplying to LVL.
- rates: Core payload. For metals, often given as metal-per-USD. Invert to USD-per-metal when you need money per unit of metal.
- unit: “per troy ounce” — very important for inventory and accounting conversions.
Practical considerations a beginner might miss
- Units and conversions:
- Troy ounces vs grams: 1 troy ounce = 31.1034768 grams. Decide on a canonical unit for internal storage.
- For jewelry pricing with carats: ensure you understand the Carat endpoint conventions and convert weights consistently.
- Base currency assumptions:
- By default, metals are quoted relative to USD. This is why you invert the rate to get USD per troy ounce before multiplying by LVL per USD.
- If you change base currency in your plan, re-check logic and update inversion steps accordingly.
- Timestamps and timezone:
- Responses are time-stamped in UTC. Align LVL FX rates to the same date boundary and timezone to avoid off-by-one-day errors.
- Clearly define your “trading day” in your database schema.
- Weekends and market closures:
- Some instruments have no trading on weekends or holidays. Your time series may skip dates or hold last-known values.
- Decide whether to forward-fill for chart continuity or keep gaps for strict market-closure integrity.
- Caching to save requests:
- Historical data changes rarely; cache long windows with a reasonable TTL.
- Bust caches selectively when your analytics window slides or when you upgrade plans.
LVL use cases infused with digital transformation
Even as LVL is historical, the workflows you develop build muscle for modern multi-currency analytics. Consider these forward-looking scenarios:
- Smart ERP integrations: Dynamically price historical orders or support revaluation audits by back-ending your ERP with Metals-API to fetch on-demand LVL prices by date.
- Quant research: Engineer LVL-based metal factors (e.g., LVL-denominated momentum, volatility clusters, rolling maxima from Lowest/Highest) and compare across currency regimes.
- Fintech dashboards: Allow users to select a legacy currency like LVL and instantly render a normalized chart across multiple metals and windows.
- Manufacturing costing: Trace the historical LVL-denominated cost of a BOM where metals are line items; roll up to a product-level LVL valuation for archival documentation.
End-to-end reliability: authentication, security, and governance
- Authentication:
- Use your API Key via the access_key parameter in the base URL query string. Never hardcode in client-side code that ships to browsers; keep it server-side or in a secure secrets manager.
- Transport security:
- Always call the API over HTTPS. Keep TLS libraries patched and verify certificates as per your platform’s defaults.
- Key rotation:
- Support multiple active keys for rolling rotations with zero downtime.
- Tag requests with correlation IDs for observability.
- Access control and least privilege:
- Restrict which microservices can read the API key. Apply IAM roles and audit access.
- Data governance:
- Store raw JSON responses alongside your transformed LVL series for traceability. Attach the timestamp and date window used to convert to LVL.
Performance, rate management, and scaling
- Batch your requests:
- Use Time-Series to pull multiple days in one call rather than iterating day-by-day.
- Request multiple metals at once (symbols=XAU,XAG,...) if your use case needs them together.
- Cache aggressively:
- Historical responses can be cached for long durations. Meme them in a CDN or Redis layer.
- If you compute LVL series from USD metals + USD→LVL, also cache intermediate FX values.
- Retry strategy:
- On transient network errors, back off exponentially. Avoid hot loops that can waste quota.
- Pagination and windowing:
- If your plan or endpoint has date limits per request, segment long historical ranges into monthly or quarterly windows and parallelize safely within rate limits.
- Observability:
- Log request IDs, timestamps, symbols, and response sizes. Alert on anomalies in success flags or missing fields before they propagate into analytics.
Advanced analytics patterns with LVL
- Normalize and compare across metals:
- After you have LVL-per-oz series for XAU, XAG, XPT, XPD, compute relative value ratios (e.g., gold/silver ratio in LVL). These can differ subtly when you use a non-USD currency baseline.
- Regime detection:
- Use Fluctuation or OHLC to detect volatility regimes under LVL normalization. Then, run a change-point detection algorithm to identify shifts in metal-market behavior during the LVL era.
- Event studies:
- Mark macro events and compare pre/post LVL-denominated return distributions for each metal.
- Inventory valuation:
- Apply OHLC with LVL conversion to compute end-of-day valuation bands for inventory audits for a given historical date, using close as your book value and low/high for sensitivity.
Practical endpoint-by-endpoint guidance folded into LVL workflows
Latest: real-time LVL snapshotting
Purpose: Up-to-date pricing for dashboards and alerts. After fetching the latest USD-based metals, convert to LVL with USD→LVL. Performance tip: cache the last snapshot to smooth UI refreshes; avoid over-polling.
Common pitfalls:
- Forgetting unit inversion before converting to LVL.
- Mixing timestamps—ensure the USD metals and USD→LVL are aligned enough for your UX (some UI panels accept slight time skew).
Security best practices:
- Do not expose your access_key in browser calls; serve from your backend.
Historical: single-day LVL reconciliation
Purpose: Correct, immutable price on a specific date. Use this for audits, settlement validation, or reconciling historical tickets. Always store the date, timestamp, and the exact USD→LVL used.
Troubleshooting:
- If the date falls on a weekend/holiday, verify behavior (last trade vs. no data). Decide whether to forward-fill or to mark as non-trading day in your pipeline.
Time-Series: LVL backfilling and rolling analytics
Purpose: Build long LVL-denominated histories. Batch across months, cache the raw USD series and the computed LVL series separately for reproducibility.
Optimization:
- Parallelize by month or quarter respecting your plan’s request limits. Persist intermediate results to restart gracefully after failures.
Convert: the bridge from USD to LVL
Purpose: Provide the LVL per USD rate to transform USD-based metal prices to LVL. For robust analytics, fetch a rate per day in your time window.
Notes:
- Always document whether Convert’s date alignment meets your governance requirements. If you cannot pin the date directly in Convert under your plan, consider storing the timestamp and describing your alignment logic.
Fluctuation: LVL movement metrics
Purpose: Build LVL-specific change metrics by transforming start/end to LVL. Use this for alerting, daily summaries, and portfolio commentary in legacy currency terms.
Common pitfalls:
- Using USD-based change_pct directly as LVL-based changes when USD→LVL also moved over the window. Recompute in LVL for precise reporting.
OHLC: LVL candlesticks and risk bands
Purpose: Capture intraday structure but report in LVL. Ensure consistent FX alignment per OHLC field if your downstream analytics require it.
Bid/Ask: LVL execution modeling
Purpose: Convert bid and ask separately to retain spread characteristics in LVL space. Useful for historical slippage modeling and benchmarking execution quality.
Carat: LVL retail and component pricing
Purpose: Serve LVL-based prices per carat for catalogs or quotes linked to LVL-era records. Confirm unit consistency (troy ounce vs carat conventions) before applying FX.
Historical LME: long-span LVL research
Purpose: Pull extended LME history, then convert to LVL. Combine with Time-Series and Fluctuation for regime analysis across commodity cycles.
Handling weekends, holidays, and non-trading days
- Data gaps:
- When no trades occur, you may see no fresh rates. Decide whether to forward-fill LVL prices for charts or to display gaps with clear tooltips explaining closures.
- Auditing:
- For financial statements tied to specific calendar days, maintain a policy for using last available close and document it clearly.
Data validation, sanitization, and error handling
- Validate success field:
- Check success == true; if not, log the payload and retry or escalate according to your SLOs.
- Schema checks:
- Ensure expected fields exist (timestamp, base, date(s), rates). Missing fields should trigger warnings in CI/CD tests and runtime monitors.
- Sanitize symbol lists:
- Validate requested symbols against the official symbol list before calling endpoints. Reject typos early.
- Recovery strategies:
- On transient HTTP failures: exponential backoff. On persistent errors: alarm, switch to cached values, and annotate affected downstream outputs.
Caching and persistence model for LVL pipelines
- Layers of caching:
- Response cache: Store raw JSON from Historical/Time-Series to reproduce any LVL series later without re-querying metals.
- FX cache: Persist USD→LVL daily rates aligned to your dates.
- Derived cache: Store computed LVL-per-oz series; add metadata with hash of inputs for auditability.
- Invalidation rules:
- Historical windows: long TTL or permanent storage.
- Latest/Intraday: short TTL; roll to historical after close.
- Compression:
- Compress JSON at rest to reduce storage overhead for long spans and multi-symbol portfolios.
Compliance, audit trails, and reproducibility
- Provenance:
- Record the access_key used, endpoint, URL with parameters (masked key), timestamp, and the full JSON response.
- Deterministic calculations:
- Use precise decimal math and fix rounding rules (e.g., half-up to 4 decimals for LVL per oz) per your finance policy.
- Documentation:
- Link your data lineage docs to the Metals-API Documentation so investigators can map fields easily.

FAQ
- Does Metals-API support LVL directly?
Check the Supported Symbols list. If LVL is available, you can use it directly. If not, use USD metals plus USD→LVL conversion where supported by your plan and documentation. - Are metals quoted per troy ounce?
Yes. The unit field in responses indicates “per troy ounce.” Convert to grams if needed: 1 troy ounce = 31.1034768 grams. - What timezone do dates use?
UTC. Align your FX and metals data to the same UTC day boundaries to avoid off-by-one errors. - How should I handle weekends and holidays?
Decide on a policy: forward-fill for charts or leave gaps to reflect closures. Document this in your analytics notes. - Can I get bid/ask or OHLC in LVL?
Yes—fetch bid/ask or OHLC in USD and convert each component to LVL using the corresponding USD→LVL rate for the relevant time convention. - What’s the best way to optimize requests?
Use Time-Series for batch pulls, cache historical results, and implement exponential backoff on retries. Avoid per-day loops when a single call can return multiple days. - Where do I start?
