AttestPage

Use when an agent relies on a web page it read earlier and needs page change detection (does it still say the same thing?): send the receipt from an earlier fetch, verify/quote or recheck call (or a URL and the content_sha256 from our fetch), and get back unchanged, changed, gone or unreadable, the fields that differ, and a signed receipt naming both hashes, which chains to the next recheck. Nothing is stored and nothing calls you back. PDFs: full service only. 5 free calls a day.
