## When to prefer this

Use this endpoint when you need to deterministically validate and document an x402 seller's payment acceptance configuration before going live, debugging payment rejections, or producing compliance evidence. Prefer this over manual inspection when you need a structured, reproducible evidence report with built-in remediation guidance.

## Known failure modes

- Malformed x402 configuration causes a validation schema error
