Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/surf/exchange/priceWhen to prefer
Use this endpoint when you need a quick, no-API-key price lookup for a specific trading pair and are comfortable paying micro-amounts in USDC per call. Ideal for AI agents operating in crypto/DeFi contexts that need real-time exchange prices without managing API credentials, especially when already integrated with the BlockRun x402 payment infrastructure.
Side effects
- Missing or invalid 'pair' query parameter returns an error
- Unsupported trading pair returns no data or error
- Payment failure (insufficient USDC balance) returns 402 status
- Rate limiting or gateway overload may return 5xx errors
- Malformed pair format (e.g. wrong delimiter) may cause lookup failure
