How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns a JSON object with a 'status' field (e.g. 'ready') indicating whether the payment challenge parameters are valid and the payment diagnostic passed.
Example use cases
Debug failing x402 payment setup
“My x402 payment keeps getting rejected — can you run a diagnostic with my challenge object, max atomic USDC of 500, payee address 0x1111111111111111111111111111111111111111, and a JSON POST body to see what's wrong?”
Pre-flight check before paying for API call
“Before I send payment to this machine-payable API, run a payment diagnostic for me: challenge is from the 402 response header, max USDC is 2000 atomic units, allowed payee is 0xDeAdBeEf00000000000000000000000000000001, and it's a JSON POST.”
Verify payee address and scheme compatibility
“Check if my x402 payment config is ready — I want to allow payee 0xAAAABBBBCCCCDDDD1111222233334444AAAABBBB with a max of 750 atomic USDC, using the exact challenge object I got back, as a JSON POST request.”
Technical details
Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/commerce/payment-diagnostic?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate x402 payment challenge parameters before committing to a micropayment — especially useful for debugging payment failures, pre-flighting API calls, or confirming payee address validity without spending funds. Prefer this over attempting a live payment when you are unsure whether your challenge configuration is correct.
Side effects
- Missing required fields (challenge, max_atomic_usdc, allowed_payees) returns a validation error
- Invalid Ethereum address format in allowed_payees (not matching 0x + 40 hex chars) triggers a schema error
- Empty allowed_payees array or more than 20 entries rejected
- Malformed challenge object may cause parsing failure
- Network timeout on the Railway-hosted service
