Metals-API vs Metals.dev

Metals-API and Metals.dev sit in the same weight class: broad multi-metal catalogs, wide currency lists, and a pitch built on coverage rather than a single specialist metal.

Pricing: Metals.dev opens far cheaper

A $1.79/mo entry plan against $29/mo is a wide gap for anyone testing a metals feed before committing budget. The gap compresses at production volume, $39.99/mo for 100,000 requests on Metals.dev against $99/mo on Metals-API, but Metals.dev still comes out cheaper at both ends in the figures each provider publishes.

The overage behavior differs too. Metals-API auto-bills past quota. Metals.dev's page frames its overage handling as a plan-based quota instead, a distinct policy rather than a synonym for the same thing.

Naming the source behind the number

Metals.dev is the more specific of the two about where its prices come from: it names LBMA, LME, MCX, and IBJA as blended inputs, though it doesn't publish the blend weights or per-source attribution on individual responses. Metals-API's own comparison page makes no equivalent claim about a specific benchmark authority, so that traceability advantage sits with Metals.dev based on what's actually published.

Coverage and freshness

Both list broad currency support at 170+. Metals.dev additionally lists platinum and palladium, which Metals-API's own page doesn't specifically address even while claiming broad industrial-metals breadth elsewhere. Metals.dev also publishes concrete freshness and history figures, up to a 60-second delay on real-time data and 5+ years of history capped at a 30-day window per request, where Metals-API's page stays general (historical and time-series data) without matching detail.

Frequently asked questions

Where's the biggest price gap between these two?

At the entry rung. Metals.dev's cheapest paid plan is $1.79/mo for 2,000 requests, against Metals-API's $29/mo. At the top end the gap narrows some: $39.99/mo for 100,000 requests on Metals.dev versus $99/mo on Metals-API.

Does either name its actual pricing benchmarks?

Metals.dev does, explicitly: it states its numbers blend LBMA, LME, MCX, and IBJA rates into a single figure per metal, without publishing the blend weights. Metals-API's own page doesn't name a specific benchmark authority.

Which covers platinum and palladium?

Metals.dev, per its own coverage list. Metals-API's page doesn't specifically address platinum or palladium, even though it markets broad industrial-metals coverage elsewhere on the same page.

How fresh is the data on each?

Metals.dev states its real-time data can lag up to 60 seconds. Metals-API's own page doesn't publish an equivalent freshness figure, so a direct comparison isn't possible from public sources.

What's the historical data window like?

Metals.dev states 5+ years of history with a 30-day maximum per single request, meaning a longer pull requires multiple calls. Metals-API's page references historical and time-series data without a stated depth or per-request limit.

Is either one a drop-in replacement for an existing integration?

Only Metals-API makes that specific claim, stating its endpoint shape follows the Fixer.io convention. Metals.dev's page doesn't claim compatibility with another provider's API shape.
