Repair one x402 route's Bazaar discovery metadata in one call
Repair one x402 route's Bazaar discovery metadata in one call. Send a resource URL and one real sample output; get the defect report plus a complete discovery package — full output schema inferred from the sample, a sub-500-char description with a use-when sentence, OpenAPI and well-known snippets, paste-in instructions — that ships only after passing both x402 SDK validators. Use this when your listing is hollow, invalid, or invisible in the Bazaar.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
