Building a structured metals & market-data API
Global Metals Intelligence is building a developer platform around the same verified, source-attributed market data this site already shows its own visitors — never a fabricated or estimated figure, and never a price this platform cannot trace back to a real observation.
Available platform foundation
A versioned API contract already exists at /api/v1, covering Gold and Silver reference prices, currency conversion rates, and historical monthly price records. Every response uses one consistent envelope — a status field, the data itself (or null when nothing verified is available), and a request timestamp — documented in full on the Documentation page.
This foundation is real and already tested — it is not yet a generally available commercial product. See Documentation for exactly what is safe to build against today.
Versioned by design
Every response carries its own apiVersion field. A future breaking change ships as a new version, never a silent change to what v1 already returns — the same discipline this platform already applies to every calculation and figure on its own pages.
Freshness and reliability, stated honestly
Every figure states its own status — reference, historical, stale, or unavailable — rather than presenting cached or out-of-date data as current. When no verified observation exists, the API says so plainly instead of estimating one. This is the same freshness and provenance philosophy this platform already applies to every price card and calculator; see Sources & Data Methodology for the full detail.
Security-first access, authenticated and rate-limited
A signed-in visitor can generate, name, and revoke their own API key — and a key now genuinely unlocks historical Gold/Silver data, authenticated and rate-limited from day one (60 requests per rolling 60-second window, per key). Current Gold, Silver, and most FX pairs remain unavailable through this API at any key status, per this platform's own data-provider licensing terms — see Documentation for the exact authentication and rate-limit contract.
Planned — not yet available
General Gold/Silver/FX API access for third-party applications, Widgets, and a Widget Builder remain planned directions for this platform. None of them is available today, and this page makes no claim about when any of them will ship. They depend on confirming data redistribution terms with this platform's own data providers before they can open — see Sources & Data Methodology for how this platform already treats provider licensing.
