Dropbox Sign accounts, API apps, teams, fax lines, fax delivery, and isolated fax document downloads. Generated from Dropbox Sign's immutable official OpenAPI at commit 31136f9035133acb5f055a94f24e006857210fdb. This leaf carries 28 of the suite's 73 catalog operations over 68 unique admitted official routes. Full-page aliases are separate from single-page compatibility IDs, so existing workflow bounds stay stable. The ingredient uses the origin-only API base and explicit /v3 wire paths; the documentary alias reconciles that prefix to the official path table. JSON alternatives are selected instead of multipart bodies, binary request fields are omitted in favor of URL/structured alternatives, binary GET responses become private file_refs, unsafe JSON integers remain exact strings, reads are uncached, sensitive reads are marked sensitive-read, and every mutation is approval-gated.
