How this service works
Paid agent discovery readiness audit route for autonomous agents. Returns JSON with provenance, route-specific evidence, and machine-readable fields. Price 0.10 USDC on Base via x402. Demo/preview: https://wellknown-audit-corpus.mtree.workers.dev/demo/compare. Contact: https://wellknown-audit-corpus.mtree.workers.dev/contact.
Output
A JSON object containing a side-by-side comparison of two agent-discovery well-known routes, including provenance metadata, per-route evidence, machine-readable readiness scores, and compliance field analysis for each route.
Example use cases
Example prompt
“Can you run a discovery readiness comparison audit on these two well-known routes — https://example-a.com/.well-known/agent and https://example-b.com/.well-known/agent — and tell me which one scores better on machine-readable compliance fields and why?”
Technical details
Endpoint
POSThttps://wellknown-audit-corpus.mtree.workers.dev/v1/wellknowns/compareWhen to prefer
Use this endpoint when you need a paid, authoritative side-by-side comparison of two agent-discovery well-known routes with machine-readable evidence and provenance — especially when evaluating compliance for agentic marketplaces or verifying which of two implementations better supports autonomous agent discovery. Prefer this over the single-route readiness report endpoint when the goal is comparative analysis rather than standalone assessment.
Side effects
- Missing or invalid route URLs in POST body returns a 4xx validation error
- Route URLs that are unreachable or return non-JSON result in evidence gaps or partial audit
- Payment not completed via x402 (0.10 USDC on Base) results in 402 Payment Required before audit is run
- Routes with no well-known agent discovery signals may return low-confidence or empty evidence fields
