# Get a presigned download URL for a document

GET https://api.pyramid-ai.com/api/v2/documents/{id}/download

Returns a short-lived presigned URL (10-minute expiry) for downloading the
original source file. Use this to trace AI-generated citations back to the
source document — critical for compliance audit trails.

## Authentication

- `Authorization` header (bearer token, required) — Pyramid API key (prefix with "Bearer ")

## Servers

- `https://api.pyramid-ai.com` (Production, default)
- `https://api-staging.pyramid-ai.com` (Staging (sandbox) — use pai_test_* keys)

## Request

### Path parameters

- `id` (string, required)

## Response

### 200

Presigned download URL

- `request_id` (string, required) — Server-generated per-request UUID. Also sent as `X-Request-Id` response header. Include in support tickets.
- `success` (any, required)
- `data` (DownloadResponse, optional)
- `pagination` (Pagination, optional) — Present only on list endpoints. Top-level (not nested inside `data`).

## Errors

### 401 Unauthorized Error

Unauthorized

- `success` (any, required)
- `error` (ApiErrorError, required)
- `request_id` (string, required)

### 404 Not Found Error

Resource not found

- `success` (any, required)
- `error` (ApiErrorError, required)
- `request_id` (string, required)

## Types

### DownloadResponse

- `document_id` (string, required) — The document this download URL is for.
- `file_name` (string, required) — Original file name.
- `content_type` (string, required) — MIME type of the file.
- `size_bytes` (integer, required, nullable) — File size in bytes (null if unknown).
- `download_url` (string, required) — Short-lived presigned URL for downloading the file.
- `expires_at` (datetime, required) — When the download URL expires (approximately 10 minutes from generation).

### Pagination

Offset-based pagination for list endpoints. Clients compute `has_more` from `offset + data.length < total`. Cursor pagination may be added per-endpoint later if deep-pagination performance becomes a concern.

- `total` (integer, required) — Total item count matching the filters (ignoring limit/offset).
- `offset` (integer, required)
- `limit` (integer, required, default: 50)

### ApiErrorError

- `code` (enum, required)
  - Allowed values: `VALIDATION_ERROR`, `UNAUTHORIZED`, `FORBIDDEN`, `FEATURE_NOT_ENABLED`, `AGENT_NOT_ENABLED`, `QUOTA_EXCEEDED`, `NOT_FOUND`, `CONFLICT`, `IDEMPOTENCY_KEY_REUSED`, `IDEMPOTENCY_IN_PROGRESS`, `UPLOAD_NOT_FOUND`, `UPLOAD_SIZE_MISMATCH`, `RATE_LIMITED`, `INTERNAL_ERROR`
- `message` (string, required) — Human-readable description. May be shown to end users; keep stable across minor changes.
- `docs_url` (string, optional) — Link to the error's documentation section.
- `field` (string, optional) — Only for `VALIDATION_ERROR`. JSONPath-ish reference to the offending field (e.g. `body.project_id`).
- `feature` (string, optional) — Only for `FEATURE_NOT_ENABLED`. The feature key the request required.
