Get a short-lived signed download URL for a document

GET 
/api/v1/documents/:id/download

Required scope: dpp:read. Returns a 2-hour signed URL to the file (Content-Disposition: attachment). The document must belong to your company — a cross-tenant or supplier-standalone document returns 404 (no existence oracle). Rate-limited per key.

Signed URL

403

403 — missing scope (FORBIDDEN_SCOPE) or module (FORBIDDEN_MODULE).

404

Document not found / not owned (NOT_FOUND), or no file stored (NO_FILE).

429

429 — RATE_LIMITED (per-key limit, reads and writes alike; fails closed, so a limiter outage also returns 429). A limiter-down 429 is deliberately indistinguishable from a quota 429. Carries Retry-After (seconds).
