# Audit Alpha Landing-Page Evidence Audit

Read the free `GET /sample.json` document to inspect the exact result shape. Use the free `POST /preview` endpoint when one finding for a real public page is enough. For the paid audit, send JSON containing `source_url` and optional `conversion_goal`, `audience`, and `offer`.

Autonomous buyers that prefer a discoverable GET request may call `GET /api/x402/landing-page-audit?source_url=https%3A%2F%2Fexample.com` with the same optional fields as query parameters.

For a low-cost machine-readable audit rubric with no input, use `GET /api/x402/checklist`.

The paid endpoint uses x402 on Base mainnet with native USDC. Read the live HTTP 402 challenge, authorize exactly the quoted amount and retry the identical request with the payment header. Never send credentials or a private URL.

The result is a bounded static-HTML review, not a promise of traffic, rankings, conversions, revenue, accessibility compliance, or legal compliance.
