Call it yourself

Bearer token + one GET. MCP-native agents on Free already.

curl -H "Authorization: Bearer ga_live_..." \
  "https://api.goldprice.dev/v1/prices?symbol=HG-USD-SPOT"

const res = await fetch(
  "https://api.goldprice.dev/v1/prices?symbol=HG-USD-SPOT",
  { headers: { Authorization: `Bearer ${process.env.GOLDPRICE_API_KEY}` } }
);
const { symbols } = await res.json();
const row = symbols[0];
console.log(row.price, row.sources); // pass-through sources[]
