Gold Price API
Gold spot prices from official-source data with historical access back to 2004. Multi-currency, weight unit conversions, FX, commodity, and MCP access under one shared API key.
Prices are indicative and sourced from averaged public data (Central Banks, digital markets). They do not constitute an official LBMA fixing.

Why Choose Our Gold Price API
Built on official central bank data with transparent sourcing and developer-friendly design.
Official Central Bank Data
Gold prices sourced from sovereign central bank institutions, not commercial data resellers. FX conversions use official ECB reference rates.
26+ Currencies
Get gold prices in USD, EUR, GBP, JPY, CHF, AUD, CAD, PLN, CNY, INR, and 16+ more currencies. All converted using official ECB exchange rates.
Historical Data Since 2013
Access daily gold prices going back to 2004, including older Kaggle-backed history plus official central-bank-derived spot pricing for current periods.
Simple REST JSON API
Clean, predictable JSON responses. Standard HTTP methods. API key authentication via header. Integrate in under 10 minutes.
Multiple Weight Units
Get prices per troy ounce, gram, kilogram, tola, or tael. Weight conversion is built into the API so client apps do not need custom metal math.
Shared Plan Across Products
The same plan model unlocks gold, FX, commodity, and MCP access. Free gives spot access; paid unlocks historical endpoints and broader request limits.
SentiSignal vs. Typical Gold API Providers
The product is positioned for developers who need one key for gold, FX, and commodity workflows instead of stitching together separate vendors.

}Source reality and usage model
Gold API is the gold-specific entry point into the broader Metals API product and the wider Finance Hub API suite. The product is informational: it is designed for reporting, analytics, research, and app experiences, not as investment advice or an execution-grade trading feed.
Gold source attribution
Gold responses include source attribution and price date. The strongest official anchor in the stack is NBP for gold, with composite handling documented in Metals API responses.
FX source attribution
Currency conversion is based on ECB reference-rate data via the Frankfurter stack. FX rates are daily reference data, not intraday executable quotes.
Freshness model
Freshness is tied to source publication cadence. Gold and FX should be treated as daily reference data with explicit timestamps and publication dates in the response payload.
