Two different bets on precision

GoldAPI.io bets on depth within a narrow catalog: gold and silver, LBMA fix redistribution rights, and LBMA AM fix (1968+). Metals.dev bets on breadth: nine metals under one key, with LBMA, LME, MCX, and IBJA blended together rather than exposed as separate rows. Neither approach is wrong, they're built for different buyers.

Pricing

For GoldAPI.io, its plan listing shows Sandbox (up to 100 requests/month) and Unlimited ($99/month).

Coverage: narrow vs broad

GoldAPI.io claims the deeper historical record for LBMA AM fix since 1968 against Metals.dev's 5+ years, and Metals.dev caps any single historical request to a 30-day window. Metals.dev wins decisively on catalog width: platinum, palladium, aluminum, copper, nickel, lead, and zinc are all in scope, none of which GoldAPI.io's own comparison page claims to cover.

Source attribution

Metals.dev names its authority sources (a dedicated LBMA/LME/MCX/IBJA endpoint exists) but still returns one blended number per metal without disclosing how the blend is weighted. GoldAPI.io's per-source attribution is not stated in our sources.

Frequently asked questions

What's the core difference between GoldAPI.io and Metals.dev?

GoldAPI.io focuses on gold and silver, holds LBMA AM/PM fix redistribution rights, and claims LBMA AM fix history since 1968. Metals.dev covers a much wider catalog, gold, silver, platinum, palladium, aluminum, copper, nickel, lead, and zinc, on one key, and blends LBMA, LME, MCX, and IBJA into a single number per metal rather than exposing them separately.

Which one is cheaper to start with?

metals.dev is cheaper: Free has 100 requests/month with no card required; Copper is $1.79/month for 2,000 requests. For GoldAPI.io, its plan listing shows Sandbox 100 requests/month and Unlimited $99/month.

Which one has deeper historical gold data?

GoldAPI.io claims LBMA AM fix history since 1968. Metals.dev states 5+ years of XAU daily history with a 30-day maximum window per historical request, a meaningfully shallower and more request-constrained offering. If historical depth on gold specifically is the deciding factor, GoldAPI.io's own claim is the stronger one.

Does either one break out prices by benchmark source?

Metals.dev is the closer fit here, with a dedicated endpoint naming LBMA, LME, MCX, and IBJA rates, though it still blends them into one number per metal without disclosing blend weights. GoldAPI.io's per-source attribution is not stated in our sources.

Which API covers more metals beyond gold?

Metals.dev, decisively. Its catalog spans platinum, palladium, aluminum, copper, nickel, lead, and zinc alongside gold and silver, all under one key. GoldAPI.io's public comparison shows silver at spot and futures parity with gold, but no copper futures and no broader industrial-metals catalog.

Where does goldprice.dev fit next to these two?

goldprice.dev sits closer to GoldAPI.io's precious-metals focus than to Metals.dev's broad industrial catalog, but adds gold, silver and copper spot on every plan, live spot and dealer prices from Basic ($19/mo), plus a per-source sources[] array on every plan.
