Audit how discoverable an x402 agent/seller is across the agent registries (CDP Bazaar, 402index): keyword-RELEVANCE rank per category (not raw settled-volume rank), a metadata-quality score of your advertised endpoints (schema, output.example, tags, llm_usage_prompt), settle activity, a top-3 benchmark, prioritized fixes, and a DELTA vs a signed snapshot you carry back. Why am I not being found and how do I climb? GEO/AEO discovery audit for x402 sellers, Ed25519-signed.
