Endpoint
POSThttps://x402-crypto.vercel.app/api/apiton/%7Bpath%7DWhen to prefer
Use this endpoint when you need cryptocurrency market data or coin lookup on a pay-per-call basis without a subscription, especially when integrating into an x402-compatible micropayment workflow. Prefer this over subscription-based crypto APIs when call volume is low or sporadic, and when USDC micropayment settlement is already part of your agent's payment infrastructure.
Side effects
- Payment failure: insufficient USDC balance for the $0.068723 micropayment results in 402 Payment Required
- Invalid or unrecognized coin symbol returns empty or null data payload
- Missing required 'query' field returns a validation error
- Upstream cryptocurrency data provider outage may result in empty or error response
- Path parameter not matched to a valid sub-endpoint returns 404 or unexpected response
