# List files

GET https://api.respan.ai/api/files/

List files from the upstream OpenAI Files API using the authenticated organization key's OpenAI credentials.

Reference: https://respan.ai/docs/apis/gateway/list-files

## Authentication

- `Authorization` header (bearer token, required) — Use your Respan API key for Respan API authentication. Enter only the Respan API key value; clients send Authorization: Bearer \<RESPAN\_API\_KEY>. For /api/responses, provider credentials such as Perplexity, OpenAI, or Azure OpenAI go in Settings -> Providers or respan\_params.credential\_override in the request body, not in this authentication field.

## Request

### Query parameters

- `provider_id` (string, required) — Provider route with customer-owned credentials, for example `openai` or `parasail`.

## Response

### 200

List of files.

- `data` (list of ApiFilesGetResponsesContentApplicationJsonSchemaDataItems, required)
- `object` (string, optional)

## Errors

### 400 Bad Request Error

`provider_id` is missing.

- `error` (ApiFilesGetResponsesContentApplicationJsonSchemaError, required)

### 401 Unauthorized Error

You haven't added your own key for the provider in Settings › Providers, or the provider rejected it. Files and batches always run on your own key; Respan credits can't cover them.

- `error` (ApiFilesGetResponsesContentApplicationJsonSchemaError, required)

### 403 Forbidden Error

The API key is missing, invalid or expired.

- `detail` (string, required)

## Types

### ApiFilesGetResponsesContentApplicationJsonSchemaDataItems

- `id` (string, required) — File ID.
- `object` (string, required)
- `bytes` (integer, optional) — File size in bytes.
- `created_at` (integer, optional) — Unix timestamp.
- `filename` (string, optional)
- `purpose` (string, optional)
- `status` (string, optional) — File status.
- `status_details` (any, optional, nullable) — Provider status details, when available.

### ApiFilesGetResponsesContentApplicationJsonSchemaError

- `message` (string, required)
- `type` (string, required)
- `param` (any, optional, nullable)
- `code` (any, optional, nullable)
