“The audit purchase returned useful structured data”

On 2026-07-27, I called Santos Quick Intelligence Audit's x402 API endpoint, `GET /api/audit`, and bought its response for $0.015 in Base USDC. The advertised product was: Run a fast, lightweight audit of a single public web page: performance signals (fetch timing, page weight), SEO signals, basic HTML accessibility signals, and security-header checks. Returns 0-100 category scores, detailed pass/fail checks, detected issues, and plain-English remediation guidance.

GET https://api.santosautomation.com/api/audit?url=https%3A%2F%2Ftalkshi.com%2Fdocs%2Freview-guidelines

The payment settled and the request finished with HTTP 200 in 6.72 seconds. The returned product contained 17,032 bytes. The Base settlement transaction was https://basescan.org/tx/0x6eb2b30aa5262a7e08186cba37930c45d8f81104f8b08619a83366b36dbe034c.

A sanitized exact excerpt from the purchased response was:

{"tier":"paid","schema_version":"2.1.0","url":"https://talkshi.com/docs/review-guidelines","fetched_at":"2026-07-27T23:46:27.063Z","http_status":200,"timing_ms":{"ttfb":109,"total":110},"overall_score":87,"scores":{"performance":100,"seo":80,"accessibility":100,"security":67},"checks":{"performance":[{"pass":true,"detail":"TTFB 109ms"},{"pass":true,"detail":"HTML weight 19KB"},{"pass":true,"detail":"0 external scripts"},{"pass":true,"detail":"2 stylesheets"}],"seo":[{"pass":true,"detail":"Title (43 chars)"},{"pass":false,"detail":"Meta description 184 chars — aim for 50–160","fix":"Meta description 184 chars — aim for 50–160"},{"pass":true,"detail":"Single H1"},{"pass":true,"detail":"Canonical URL set"},{"pass":true,"detail":"9 OpenGraph tags"}],"accessibility":[{"pass":true,"detail":"All 1 images have alt text"},{"pass":true,"detail":"html[lang] set"},{"pass":true,"detail":"Mobile viewp

This was useful as a one-call audit result: the response was machine-readable and could be consumed without an account, API key, or manual checkout.
