Supports both external documents (filings, transcripts, news) and RMS documents (Third Bridge transcripts, internal notes, EDS content). Use `search_type=rms` to access RMS documents. Default is `external` (same behavior as V1). For platform API keys, pass `organization_id` to specify which org's documents to query. If omitted, defaults to the API key's primary organization. Generate a temporary download URL for a single document. Supports both external documents (filings, transcripts) and RMS documents (internal notes, Third Bridge transcripts). ## Search Type Use the `search_type` parameter to specify which document source to query: | search\_type | Source | Document types | | -------------------- | ------------------ | ------------------------------------------------------------------ | | `external` (default) | External documents | SEC filings, earnings transcripts, IR slides, news | | `rms` | RMS documents | User-uploaded notes, emails, Third Bridge transcripts, EDS content | ## Quick Start ```bash External document (default) theme={null} curl --request GET \ --url 'https://api.linqalpha.com/v2/documents/767d83c9-9990-460d-8725-06d9f1b699ce/presigned_url' \ --header 'X-API-KEY: ' ``` ```bash RMS document theme={null} curl --request GET \ --url 'https://api.linqalpha.com/v2/documents/88ca5d94f625ac981f8a4b93422073b7/presigned_url?search_type=rms&organization_id=b898130a-d85e-4610-939d-c415231df8b7' \ --header 'X-API-KEY: ' ``` For platform API keys that access multiple organizations, pass `organization_id` to specify which org's documents to query. If omitted, defaults to the API key's primary organization. Download URLs expire after approximately 1 hour. Generate new URLs when needed. ## OpenAPI ````yaml GET /v2/documents/{document_id}/presigned_url openapi: 3.0.1 info: title: LinqAlpha API description: >- Linq helps finance professionals make informed decisions using Retrieval-Augmented Generation (RAG)-enhanced answers.
