goldprice.dev vs goldapi.io
If you're comparing us to goldapi.io, here's what each of us is actually good at.
Four years of shipping, and it shows.
- →Maturity.They've been live since 2020. The API is stable, the docs have seen real users, and nobody's first in line for breaking changes.
- →LBMA fix.They hold redistribution. We don't ship it. If your use case needs the official LBMA AM/PM fix, goldapi.io is the honest answer.
- →Simpler pricing for tiny usage.Their Basic starts at $4.99. If you call the API 500 times a month and don't need MCP or real-time live oracle, they're cheaper.
- →Established integrations. There are more Stack Overflow answers, blog posts, and Zapier integrations referencing goldapi.io than us. That compounds.
Built for Polymarket + agents + methodology-aware buyers.
- ✓Every source visible. live oracle XAU + XAG, continuous spot reference, gold + silver + copper futures settlement, ECB reference rates, CoinMarketCap PAXG — each returned as its own row in
sources[]with license and timestamp. goldapi.io blends behind a single number. When prices disagree, you can't tell why. - ✓live oracle + futures settlement at prediction-market prices. Polymarket + Kalshi commodity markets resolve on a live oracle spot and futures settlement. We ship gold (XAU + GC/SI) at $10 Basic, silver + copper (XAG + HG) at $50 Pro. No other developer-tier API exposes these markets as distinct, attributed sources at this price.
- ✓MCP on every plan. We are, as of this writing, the only gold-data API with a native MCP server — and we ship it on every plan, including Free. goldapi.io has none.
- ✓Published methodology. Our methodology docnames every source, license, cadence, and use. Versioned and changelogged. goldapi.io's sourcing is a black box.
- ✓Honest staleness flag. Every response includes
is_stale: boolean. goldapi.io serves cached prices silently when upstream breaks. - ✓Spot/futures differentials + fundamentals. Basis, z-scores, ETF flows, COT positioning — things quants actually want. They stop at spot + history.
- ✓No surprise overage bills. We rate-limit and return
429. They auto-bill overage, which has bitten people.

Who should pick which
Short version: pick goldapi.io if you need the LBMA fix or the absolute cheapest paid plan. Pick us if you're building for Polymarket, agents, or care about provenance.
You need the official LBMA fix, or the cheapest paid plan.
You're building a display widget, an internal dashboard, or a compliance-adjacent product that requires the licensed LBMA benchmark — goldapi.io is a sensible, boring, proven choice.
You're building for Polymarket, agents, or quant tools — or you need market-implied distributions from prediction-market aggregation.
You're wiring gold into Claude, Cursor, or a custom agent; you need live oracle + futures settlement to mirror Polymarket market resolution; or you want to know exactly how the number was made before you bet production on it.
Still deciding?
Start on Basic for $10/mo. Keep the one that doesn't make you angry at 2am.
