POST http://list-smith-production.up.railway.app/v1/fix · 1 observation
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.

POST http://list-smith-production.up.railway.app/v1/grade · 1 observation
Grade one x402 route's Bazaar discovery metadata. Returns the diagnosis only: both x402 SDK validator verdicts, the schema-quality score, itemized defects with severities (hollow output schemas, over-500-char descriptions, wrong asset addresses, failed validation), and a 0-100 grade. Use this when you operate an x402 route and want to know exactly what is broken before paying for the repair.

POST http://logicnodes.io/paid/v1/tools/gas_estimate · 1 observation
Gas / fee estimate. Current fee tiers for a chain as decimal strings with explicit units. EVM: confidence levels (default 99/95/90/80/70) in gwei with base fee, priority fee and max fee. Aptos: deprioritized/regular/prioritized gas unit prices in octas per gas unit. Data older than its freshness budget is an error, never a stale answer.

Counts describe directory coverage, including testnets. Each resource groups the same URL, HTTP method or MCP tool across sources. A catalog sighting records published terms. A live 402 records the endpoint’s reply to an unpaid request.
