# The Shop Window

Name a public page (the url query parameter) and the store GETs it once, reads the HTML the way a machine passerby does — title, meta description, canonical, robots directives, headings, JSON-LD structured data, link shape — and signs the whole readout: verdict, every check, every advisory, dated. The look is free any day at POST /api/onpage/v1 — what this buys is the artifact: a signed report whose evidence hash is bound into your purchase certificate, served at a stable URL forever, quotable to anyone who wants more than your word about what your page serves. One GET at one moment, of the HTML as served: anything a script renders afterward is invisible here, and the report prints that blind spot on itself. Not an SEO grade, not a ranking claim, not an endorsement.

- **id:** `onpage_audit`
- **price:** $3 fixed, one-off; nothing here charges again by itself, ever — there is no mechanism that could
- **fulfillment:** delivered instantly
- **buy:** `GET https://scvd.store/api/buy/onpage_audit` (USDC over x402 v2 on Base, Polygon, Arbitrum, World, Solana, or USDC over MPP (evm/charge) on Base for every shelf item, every publication page and the commission desk)
- **sample:** https://scvd.store/samples/onpage-audit.json
- **does not prove:** What a browser would show. The battery reads the HTML as served — script-rendered content is invisible to it and the report says so on itself. Not an endorsement, not a ranking claim, and nothing about any other moment.

House rules: give the page in the url query parameter: https, default port, on the public internet; one get at one moment, of the html as served; scripts never run, and the report names that blind spot on itself; the criteria are the free desk's published battery (get /api/onpage/v1); the audit runs those checks and no others; we refuse our own hostname — an audit of ourselves signed by ourselves would be the instrument vouching for itself; the report url is free to read forever.

> Three dollars. The window is free to look through — what costs money is the signed note saying what was in it.
