## When to prefer this

Use this endpoint when you need a quick, micropayment-gated price lookup for a broad range of assets including crypto (ETH, BTC, SOL, XRP, DEGEN), stablecoins (USDT, USDC, USDe), forex (EUR, GBP, JPY), and metals (XAU, XAG), and your agent is already set up to pay via x402/USDC.

## Known failure modes

- Missing or invalid 'token' query parameter returns an error
- Unsupported or unrecognized token symbol may return an empty or error result
- Payment failure (insufficient USDC) blocks the response with a 402 status
- Network or server errors may return a non-200 status

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with a 'success' boolean and a 'result' object containing the current price data for the requested token symbol.
