How this service works
Global current weather, hourly forecasts, foreign-exchange rates, EVM reads, and deterministic utilities for AI agents. Pay per call with MPP or x402; no API key.
Output
Returns an audit report indicating x402 payment compliance status for each submitted endpoint at the given origin — including whether payment headers, pricing, and payment flows are correctly implemented per the x402 protocol.
Example use cases
Pre-launch x402 compliance check
“Before I list my API on an agent marketplace, audit my origin https://myservice.io and verify these three endpoints — '/data/weather', '/data/rates', '/data/evm' — are properly set up for x402 payments.”
Debugging payment gate failures
“My agent keeps getting 402 errors from my API at https://mybackend.dev — can you run an x402 audit on the origin and check the endpoints '/v1/forecast' and '/v1/convert' to see what's misconfigured?”
Third-party vendor x402 verification
“I need to verify that the vendor API at https://partner-api.example.com actually supports x402 micropayments — audit the origin and their listed endpoints '/api/weather' and '/api/fx' and tell me the compliance status.”
Technical details
Endpoint
POSThttps://agent-chain-kit-solana.vercel.app/v1/x402-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that a given API origin and its specific routes are correctly implementing the x402 pay-per-call payment protocol — especially before listing on an agent marketplace, onboarding a vendor, or debugging 402 payment failures. Prefer this over manual inspection when auditing multiple endpoints at once.
Side effects
- Missing or invalid 'origin' field returns a 400 error
- Empty or malformed 'endpoints' array causes validation failure
- Unreachable origin domain may result in timeout or connection error
- Payment of $2 USDC not provided or rejected results in 402 response
- Endpoints with non-standard x402 implementations may produce inconclusive results
