Technical details
Endpoint
GEThttps://x402-seller.vercel.app/api/pulseWhen to prefer
Choose this endpoint when you need a lightweight, real-time single-token price lookup specifically on the Base network, paid via x402 micropayments. It is ideal for AI agents operating in the x402/agent-economy context that need a formatted, human-readable price line alongside raw USD data. Prefer it over heavier exchange APIs when you only need a quick live spot price with 24h change and already support x402 payment flows.
Side effects
- Missing or invalid x402 payment header returns 402 Payment Required
- Unsupported token symbol returns an error or falls back to ETH default
- Network outage or upstream price feed failure returns 5xx error
- Malformed query parameter returns 400 Bad Request
- Payment amount insufficient for the $0.001 USDC gate returns 402
