Overview
GuardianCheckin Public API (1.0.0)
Section titled “GuardianCheckin Public API (1.0.0)”The GuardianCheckin Public Developer API. A stable, versioned (/v1/) read surface over your listings and forms, decoupled from GuardianCheckin’s internal data shapes (Story 37.4, FR-API-20).
Authentication is a bearer API key (Authorization: Bearer gck_live_<prefix>.<secret>) on the api.gcheckin.com host. Every request is scoped to the listings the key’s owner owns or writer-manages; out-of-scope or unknown ids return 404 with no existence disclosure.
Pagination is keyset/cursor based. nextCursor is an opaque token — treat it as a black box and pass it back verbatim as the cursor query parameter to fetch the next page. A null nextCursor means the last page was reached. Cursors are stable over inserts/deletes: a row added during iteration appears only if it sorts after your current position; already-returned pages never shift.
