Returns 409 `upload_not_found` when nothing was uploaded yet. Safe to call more than once. Statement analysis itself is started from the app (it is billed per file). ## OpenAPI ````yaml /openapi/public-v1.json post /v1/documents/{id}/finalize openapi: 3.0.0 info: title: NextLevel MCA Public API description: >- REST API for the NextLevel MCA deal platform. Objects flow Businesses → People → Deals → Submissions → Offers → Advances. **Authentication.** Send `Authorization: Bearer ` with an API key (`nlmca_live_…`, created in Settings → Developers) or an OAuth access token. Keys are scoped to one location. **Conventions.** JSON only. Cursor pagination (`limit` ≤ 100, `cursor` from `meta.next_cursor`). Every success is `{ data, meta }`; every error is `{ error: { type, message, code, param, request_id } }`. POST endpoints accept `Idempotency-Key` (24h replay). Rate limit 300 requests/min per credential (`X-RateLimit-*` headers). **Scopes.** Keys with no scopes have all of them.
