GoldAPI.io vs MetalpriceAPI

If a shortlist for a metals-focused pricing API already has two names on it, they're probably GoldAPI.io and MetalpriceAPI: both frequently recommended in the same developer threads, far apart in entry price, and both light on the details that would let a developer tell them apart at a glance.

Pricing: apart at entry, further apart in structure

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

The LBMA question

GoldAPI.io states outright that it holds LBMA AM/PM fix redistribution rights, a specific, checkable claim about its data lineage. MetalpriceAPI makes no equivalent public claim, and our own research treated that gap as unverifiable rather than assuming MetalpriceAPI lacks a comparable relationship. Anyone who needs LBMA provenance specifically should confirm directly with MetalpriceAPI rather than infer an answer from silence.

Coverage and history

MetalpriceAPI names platinum alongside gold and silver in its FAQ, one metal GoldAPI.io's page doesn't claim. GoldAPI.io counters with stated LBMA AM fix history since 1968, a figure MetalpriceAPI's page doesn't publish an equivalent for. Currency counts differ, 72 against 150+, a gap that need not matter on its own.

Is either one shipping WebSocket streaming?
