How this service works
Lint an x402 endpoint URL for Coinbase CDP Bazaar discovery readiness without paying it: checks HTTP 402, x402 v2 PAYMENT-REQUIRED header, Base USDC option, >=1000 atomic minimum, EIP-3009 extra.name/version, and extensions.bazaar schema.
Output
Returns a structured lint report indicating pass/fail status for each Bazaar discovery requirement: HTTP 402 response presence, x402 v2 PAYMENT-REQUIRED header, Base USDC payment option, minimum 1000 atomic unit price, EIP-3009 extra.name and version fields, and extensions.bazaar schema validity — all checked without triggering an actual payment.
Example use cases
Pre-listing Bazaar compliance check
“Before I submit my API to Coinbase CDP Bazaar, can you lint my x402 endpoint at https://payments.myservice.io/api/endpoint to make sure it passes all the discovery requirements — 402 status, Base USDC option, and the bazaar schema extension?”
Debugging a rejected Bazaar submission
“My GET endpoint at https://api.mybot.dev/v1/predict was rejected by Bazaar — can you run the Bazaar lint check on it so I can see exactly which x402 requirements it's failing?”
Validating EIP-3009 fields before launch
“I want to launch my x402 API on Bazaar next week — can you check https://tools.aiplatform.xyz/v2/generate with a GET to confirm the EIP-3009 extra.name and version fields and the 1000 atomic minimum are properly configured?”
Technical details
Endpoint
GEThttps://bot-bazaar.fly.dev/v1/x402/bazaar-lint?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific x402 endpoint is fully compliant with Coinbase CDP Bazaar discovery requirements before submitting or after configuration changes. It is the authoritative pre-flight check for Bazaar listings, covering all required x402 v2 fields, Base USDC support, EIP-3009 metadata, and the extensions.bazaar schema in a single call without incurring payment costs.
Side effects
- Target URL is not publicly reachable (timeout or DNS failure)
- Target URL does not return HTTP 402 at all (lint fails hard)
- URL is not HTTPS or uses a non-public host (rejected by schema validation)
- Missing required 'url' query parameter returns 400 Bad Request
- Target endpoint uses an incompatible HTTP method beyond GET/HEAD/DELETE
