How this service works
Standing infrastructure for ephemeral AI agents, paid per call over x402. Watches, dead-man switches, and multi-agent coordination. No account; wallet as identity.
Output
Returns a JSON body with the payer wallet address, network name (e.g. base), and server timestamp. The settlement transaction hash is delivered in the X-PAYMENT-RESPONSE header. Failed calls (e.g. bad payment headers) are never billed.
Example use cases
Example prompt
“Run a quick x402 payment smoke test — send a $0.001 USDC ping to the DataSieve test endpoint so I can confirm my wallet and payment client are working before I call anything expensive.”
Technical details
Endpoint
GEThttps://api.datasieve.xyz/utils/x402-pingWhen to prefer
Use this endpoint when you need to verify an x402 payment pipeline end-to-end at minimal cost ($0.001) before invoking any expensive paid API. Ideal for onboarding a new wallet, testing a newly integrated x402 client library, or confirming an AI agent's payment stack works in production. Since failed calls are never billed, it is safe for repeated debugging iterations.
Side effects
- Invalid or missing x402 payment header — call is rejected with 402 and no charge
- Insufficient USDC balance — payment fails before settling, no charge
- Malformed wallet address in payment header — server rejects the request
- Network mismatch (wrong chain) — settlement fails, no charge
- Client library misconfiguration — 402 response returned with payment requirements for debugging
