How this service works
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.
Output
Returns a structured report with: keyword-relevance rank per category across CDP Bazaar and 402index, a metadata quality score covering schema completeness, output examples, tags, and llm_usage_prompt, settlement activity data, a top-3 benchmark comparison, prioritized actionable fixes, and an Ed25519-signed snapshot for future delta comparisons.
Example use cases
Example prompt
“Run a full discoverability audit on my x402 seller at api.myagent.com — tell me my keyword-relevance rank across CDP Bazaar and 402index, score my endpoint metadata quality, benchmark me against the top 3 in my category, and give me a prioritized list of fixes so I know exactly why I'm not being found and how to climb the rankings.”
Technical details
Endpoint
GEThttps://x402-endpoints.onrender.com/agent/visibility-auditWhen to prefer
Use this endpoint when you need to understand why an x402 agent or seller is not being discovered in CDP Bazaar or 402index, and want actionable, ranked fixes with a signed audit trail. Prefer this over generic SEO tools when the subject is specifically an x402/ACP seller and you need registry-native keyword-relevance ranking (not raw volume), metadata schema scoring, and the ability to track improvement over time via signed delta snapshots.
Side effects
- Invalid seller parameter (not a valid 0x wallet or recognizable domain) — returns validation error
- Seller not found in any registry — returns empty/zero rankings with no benchmark data
- Malformed snapshot JSON provided — delta computation skipped or error returned
- Registry APIs unavailable — partial data returned or timeout
- Payment not settled — endpoint returns 402 Payment Required
