## 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 x402-bazaar-audit-http-402-seller-compliance-checker-4818b262 -d '<json body>'
```

Example prompt: Can you audit my x402 seller endpoint for Bazaar indexing? Here's my HTTP 402 PaymentRequired JSON — tell me if it passes and flag any common seller bugs like bad extension shape, schema issues, URL problems, or description length violations.

## When to prefer this

Use this endpoint when you have built or are debugging an x402/HTTP 402 seller endpoint and need to verify it will be accepted and indexed by Coinbase Bazaar. Prefer this over manual schema inspection when you want automated, loop-friendly compliance checking with specific bug callouts at $0.01 per check.

## Known failure modes

- Missing or malformed input body returns validation error
- Non-JSON body type rejected — only json bodyType accepted
- Non-POST method rejected
- Malformed 402 JSON that cannot be parsed returns parse error
- Payment failure (USDC balance insufficient) blocks the audit
- Timeout if payload is unusually large

## How this service works

Diagnose why an x402 seller is invisible on Coinbase Bazaar. POST your 402 PaymentRequired JSON. Free preview: pass/fail + which checks fail. Paid $0.01: every finding with the exact fix (extension shape, AJV schema, description limits). Run before each x402 deploy.

## Output

Returns a pass/fail compliance score along with itemized diagnostics covering extension shape validity, schema conformance, resource URL format, description character limits, and a list of common seller bugs detected — helping the seller fix issues before Bazaar indexing.
