Reconcile usage and scrape docs and guard authentication references
Usage and scrape references still described timestamp-only cursors, nonnullable fields that can be null, and incomplete artist-wide pricing. The maintained source now matches API #1033: timestamp/ID paging with microsecond precision and legacy cursor compatibility, cost/ID ties, nullable usage fields, and per-profile prices with debits only for started scrapes.
The 20-post insufficient-credit example is 250,000 micro-dollar credits ($0.25); artist-wide examples distinguish the full upfront balance requirement from the eventual debit. Human references now render property-level examples, so the documented cursor and credit amounts also appear in HTML. A regression guard resolves every root/operation OpenAPI security reference and fails when the real callback scheme is removed. Generated usage/price fixtures are compared with the API mapper, cursor decoder and price helper.
Validation: all 441 Marketing tests, docs build/check, shared fixture and inventory checks, changed-file lint, and both Python publication/inventory tests pass. API full tests, lint and production build pass. Local Marketing production builds fail at Turbopack port binding, including the network-enabled attempt; the user approved pushing for Vercel preview validation. Require the final-head remote build and readback before release.
Tracks recoupable/mono#332, recoupable/mono#345, recoupable/mono#346 and the provider-free verification for recoupable/mono#336. The source inventory pins API review commit bd59b0f2; refresh to the actual API merge before coordinated Marketing release, then refresh the retained Docs copy. Mintlify routing/host repair remains deferred.
