Metals-API alternatives
Six ways to price gold, silver, and copper without metals-api.com's blended-number, no-provenance model, ranked by fit rather than by who pays for placement.
metals-api.com is a generalist metals and FX catalog: one API key, 170+ currencies, and the full precious-and-industrial-metals list from gold down to zinc. Its Fixer.io-compatible endpoint shape makes it an easy drop-in for anyone already using Fixer for currency conversion, and 15+ years of daily bars back the long-tail metals most competitors skip.
The reasons people go looking for a substitute are specific. metals-api returns a single blended value per metal with no per-source attribution, which is fine for a dashboard but harder to justify in a pricing engine that needs to know which exchange a number came from. There is no live oracle feed, no futures-settlement symbol distinct from spot, and no MCP server for agent integrations. metals-api delivers what it set out to deliver; a gold-focused product just needs different things.
The six alternatives below cover the range: broader-but-cheaper catalogs, gold-and-silver specialists, and goldprice.dev's provenance-first approach to the three metals it actually serves.
goldprice.dev
Our productmetals-api's biggest gap for a gold-focused buyer is provenance: one number in, one number out, with no record of which exchange or feed produced it. goldprice.dev ships a sources[] array on every response (via ?include=sources) with per-source license and timestamp, plus a native MCP server with nine tools on every plan, including Free. Gold spot and futures start at $10/mo Physical; silver and copper join at $30/mo Pro. Best fit for teams that have to show their work behind every quote.
metals.dev
Blends LBMA, LME, MCX, and IBJA into one number per metal, with a dedicated authority endpoint that at least names the sources being blended. 170+ currencies, gold through zinc on one key, and a $1.79/mo entry price with a free 100-requests/month tier that needs no card. Historical depth is thinner (5+ years, 30-day max window per request) than metals-api's. Fits budget-sensitive catalog use.
MetalpriceAPI
A seven-tier ladder from $3.99/mo (1,000 calls) up to $55.99/mo (500,000 calls), with update cadence scaling from daily on Free to 15-second on Business. Covers gold, silver, and platinum spot only, narrower than metals-api's full metals catalog. No WebSocket streaming at any tier. Good fit if metals-api's flat two-tier pricing doesn't match a low-volume project's actual call count.
goldapi.io
Holds LBMA AM/PM fix redistribution rights and has been live since 2020, which metals-api doesn't claim. Cheapest paid plan is $4.99/mo, cheaper than metals-api's $29/mo entry point, with 160+ currencies and 20+ years of daily history. Trades metals-api's industrial-metals breadth for a gold-and-silver-first focus with an authoritative benchmark behind it.
gold-api.com
Free real-time gold and silver pricing with no rate cap and no card required, the most generous free tier of any option here, though historical and OHLC calls cap at 10 requests/hour until the $10/mo Premium plan. No published methodology or source breakdown. A reasonable pick if the project only needs gold and silver spot and doesn't need metals-api's broader catalog.
Alpha Vantage
Worth a look only if gold is one line item in a much bigger multi-asset build: equities, forex, crypto, and a commodities endpoint covering gold, silver, copper, and several agricultural commodities alongside metals-api's dedicated metals focus. Free tier caps at 25 requests/day; paid tiers run $49.99 to $249.99/mo on rate limits rather than a monthly ceiling. A weaker fit than the others here for a metals-only catalog need.
FAQ
- Why would someone leave metals-api.com?
- Mostly for depth rather than price. metals-api serves a single blended number per metal with no source attribution, no live oracle feed, and no MCP server. Teams that need per-source licensing, a forward view, or agent-native output outgrow the catalog model even though the $29/mo entry price is competitive.
- Is there a cheaper alternative with the same currency breadth?
- Not at 170+ currencies. MetalpriceAPI covers 150+ starting at $3.99/mo, and metals.dev covers 170+ starting at $1.79/mo, though both are narrower on industrial metals than metals-api and cheaper to start.
- Which alternative is best for an AI agent or MCP client?
- goldprice.dev. It ships a native MCP server with nine tools on every plan, including Free. None of the other catalogs in this list offer MCP as of their last-verified dates.
- What if I need every industrial metal, not just gold, silver, and copper?
- Stay on metals-api, or look at metals.dev. Both ship aluminum, nickel, zinc, and other industrial metals on one key. goldprice.dev covers gold, silver, and copper only, by design.
- Does any alternative avoid metals-api's auto-bill overage policy?
- goldprice.dev returns a 429 past your quota instead of billing an overage. metals.dev uses a plan-based quota model. goldapi.io and metals-api both auto-bill.
