Technical details
Endpoint
POSThttps://api.the402.ai/v1/services/svc_47ec403301534106/purchase?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a quick, pay-per-call crypto price lookup without requiring a subscription to a traditional price feed API. Ideal for low-frequency queries where per-call micropayment via x402 is preferable to managing API keys or monthly plans. Best suited for agents operating in crypto-native or Web3 environments.
Side effects
- Unknown or unsupported cryptocurrency symbol returns an error
- Payment not processed results in 402 Payment Required response
- Upstream price feed unavailable causes service error
- Malformed request body returns 400 Bad Request
- Network timeout if the price data provider is slow
