Kairostamp change check: server-side fetch of one public http/https UR
Kairostamp change check: server-side fetch of one public http/https URL, compared against a caller-supplied prior SHA-256 or prior Kairostamp receipt id. Returns whether the response body changed, both digests, and a new time-stamped evidence receipt with its tamper-evident hash-chain entry. One call performs one check; repeat monitoring means calling again.
Kairostamp evidence snapshot: server-side fetch of one public http/htt
Kairostamp evidence snapshot: server-side fetch of one public http/https URL, returning a time-stamped receipt with the response status, content type, byte length, SHA-256 of the body, redirect chain, a text preview, and a tamper-evident hash-chain entry.
Receipt verification: read-only hash-chain verification of one existin
Receipt verification: read-only hash-chain verification of one existing Kairostamp receipt id. Recomputes the canonical SHA-256 digest, compares it with the stored chain hash, checks linkage to the preceding entry and reports whether the entry is covered by an on-chain checkpoint. Performs no outbound fetch. Single GET query parameter (receipt_id).
Sitemap lookup: locates a site's sitemap from robots
Sitemap lookup: locates a site's sitemap from robots.txt or same-origin /sitemap.xml, fetches it server-side and returns up to 100 normalized http/https URLs with the sitemap URL, document kind, count, truncation flag, a timestamp and a tamper-evident receipt. Single GET query parameter (url). One document only; child sitemaps are not fetched.
Link map: fetches one public HTML page server-side and returns up to 1
Link map: fetches one public HTML page server-side and returns up to 100 normalized, deduplicated http/https links with internal/external classification and counts, the final URL, a timestamp and a tamper-evident receipt. Single GET query parameter (url). One page only; no recursive crawling. Check crawl permission first with GET /api/v1/robots-check.
Readable text extraction: fetches one public HTML page server-side and
Readable text extraction: fetches one public HTML page server-side and returns clean plain text with the page title, final URL, HTTP status, content type, SHA-256 of the response body, a timestamp and a tamper-evident receipt. Single GET query parameter (url). Text is capped at 12000 characters; no JavaScript is executed.
Redirect audit: follows one public http/https URL server-side and retu
Redirect audit: follows one public http/https URL server-side and returns the ordered redirect chain, hop count, final URL, final HTTP status, whether the destination changed origin and whether HTTPS was downgraded to HTTP, with a timestamp and a tamper-evident receipt. Single GET query parameter (url). No response body is returned.
robots
robots.txt check: fetches the origin's /robots.txt server-side and reports whether a given URL path is allowed or blocked for a user agent, with the matched rule, the robots URL, the HTTP status, a timestamp and a tamper-evident receipt. Query parameters: url (required), user_agent (optional, defaults to *). Only robots.txt is fetched; no crawling. Pair with GET /api/v1/link-map or /api/v1/sitemap to plan an allowed fetch.
URL HTTP metadata receipt: server-side fetch of one public http/https
URL HTTP metadata receipt: server-side fetch of one public http/https URL, returning only transport metadata — HTTP status, final URL, redirect chain, content type and byte length — plus a receipt id. The response body is not returned and no content preview is stored. Single GET query parameter (url).
URL digest receipt: server-side fetch of one public http/https URL, re
URL digest receipt: server-side fetch of one public http/https URL, returning a time-stamped receipt with the HTTP status, final URL, content type, byte length, SHA-256 of the response body, redirect chain, receipt id and tamper-evident hash-chain entry. Single GET query parameter (url). One call performs one fetch; there is no monitoring and no retry.
