Why is my x402 service not listed — or listed but never paid?

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.
