LIVE ENDPOINT METADATA

Why is my x402 service not listed — or listed but never paid? Send your endpoint URL; we fetch your 402 envelope, run the exact SDK validation the CDP facilitator runs, check catalog presence, and return per-check pass/fail with concrete fix hints. Includes two undocumented traps we verified against the live facilitator: a buyer must echo your bazaar extension into the settle payload, and a description over 500 characters makes the facilitator reject every payment. Deterministic, no LLM.

METADATA PROVENANCE

Source catalog records are retained separately from live endpoint observations. Sonar score, uptime, and latency are advisory metrics. CDP indexing is not inferred from validation.
