Passing means proceed or caution. Paid-tested means a real test payment confirmed the endpoint delivers. Grades come from monitoring every endpoint about every 30 minutes; how they're made: docs. Bulk data for agents: /v1/stats, /v1/sellers.

Selling x402 outside the Bazaar?

Every endpoint in the x402 Bazaar is here automatically. If you sell somewhere else, you can still be in this catalog, graded by the same rules as everyone:

Add it yourself. Paste a paid endpoint's URL, or your domain if it publishes /.well-known/x402.json. It joins within about 10 minutes if it answers a valid x402 payment quote.
Or we find it. We read every known seller's /.well-known/x402.json daily, our ecosystem watch picks up new x402 domains, and any endpoint someone checks here is added the same way.

Free, and nobody can pay for a better grade. Agents can use POST /v1/endpoints/submit.
