# wellknown-audit-corpus Agent Discovery Readiness Comparison Audit

> wellknown-audit-corpus Agent Discovery Readiness Comparison Audit is a paid API for AI agents from wellknown-audit-corpus.mtree.workers.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Compares two or more agent-discovery well-known routes and returns a JSON audit report with provenance, route-specific evidence, and machine-readable readiness fields

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability wellknown-audit-corpus-mtree-workers-dev-2b7980e2 -d '<json body>'
```

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?

## When to prefer this

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.

## Known failure modes

- 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

## 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.

## 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.
