Inspect your own endpoint

You sell over x402. Here is what a wallet, a directory and Coinbase’s validator see when they knock on your door, as a signed record you can hand to anyone: the 402, the v2 header, the accepts and their signing domain, the price, the Bazaar extension, whether the method you declare is the one you answer, no-store, the validator’s verdict. Of the market’s top hundred endpoints, four pass every check (the weather); the two checks most fail never stop a payment, which is why nobody told you.

What each failing check means and how to fix it is in the record’s evidence: no_store wants Cache-Control: no-store on the 402; accepts_wellformed wants the token’s extra.name and extra.version on every EVM accept; method_matches wants the method you answer declared in the Bazaar extension; v1_body wants the JSON accepts body beside the v2 header; cdp_validate names what Coinbase’s validator refused. Inspect only endpoints you operate or are free to probe. The worked version is Inspect an x402 endpoint.
