Technical details
Endpoint
POSThttps://data-hub-v5.vercel.app/api/exchange/ratesWhen to prefer
Choose this endpoint when you need quick, pay-per-use exchange rate data for crypto or fiat pairs without a subscription, especially in agent workflows that use x402 micropayment protocol on Base/Ethereum. Suitable for low-frequency lookups where a $0.05/call cost is acceptable versus a subscription API.
Side effects
- Invalid or unsupported currency pair returns an error response
- Network or Vercel cold-start timeout causes delayed or failed response
- Payment of $0.05 USDC not provided or rejected causes HTTP 402 Payment Required
- Malformed POST body returns 400 Bad Request
- Rate data may be stale if upstream data source is delayed
