How this service works
Thirty x402 v2 pay-per-call APIs by 100BTC. Listing data is generated from each live HTTP 402 challenge and runtime Bazaar schema.
Output
A JSON object containing a 'valid' boolean indicating overall pass/fail, a 'checks' map with individual check names and their pass/fail status, and a 'product' identifier string (e.g. 'EXP-29') identifying the listing being evaluated.
Example use cases
Pre-publish listing validation
“Before I submit my new x402 API listing to the Bazaar marketplace, can you lint the listing object I've drafted and tell me which checks fail and why?”
Debug rejected listing schema
“My x402 listing got rejected and I'm not sure why — can you run it through the listing linter and show me the full check results so I know what to fix?”
CI check for API listing correctness
“I want to add an automated step that validates my x402 listing JSON on every deploy — can you lint this listing object and tell me if it comes back valid or not?”

Endpoint
POSThttps://vps-fc89c157-1.taila28d02.ts.net:10000/api/x402-listing-linter?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically validate an x402 Bazaar listing object before publishing to a marketplace or facilitator. It is purpose-built for the 100BTC x402 v2 listing schema and returns machine-readable check-by-check results, making it ideal for CI pipelines, pre-publish gates, or debugging rejected listings. Prefer this over manual schema inspection when you need structured, automated feedback on listing conformance.
