# List Files

`GET /v1/files?beta=true`

## Query parameters

- `page` string, nullable — Opaque page cursor returned in a prior list response's `next_page`. Prefixed `page_`.
- `ids[]` string[], nullable — Restrict the result set to Files whose `id` is in this list. At most 100 entries (after de-duplication). Mutually exclusive with `page` and `limit`. When supplied, the response is always a single page (`next_page` is null). IDs that do not resolve to a visible File — including deleted Files — are silently omitted.
- `limit` integer — Number of items to return per page. Defaults to `20`. Ranges from `1` to `1000`.
- `scope_id` string — Filter by scope ID. Only returns files associated with the specified scope (e.g., a session ID).

## Headers

- `anthropic-beta` string — Optional header to specify the beta version(s) you want to use. To use multiple betas, use a comma separated list like `beta1,beta2` or specify the header multiple times for each beta.
- `anthropic-version` string — The version of the Claude API you want to use. Read more about versioning and our version history [here](https://platform.claude.com/docs/en/api/versioning).
- `x-api-key` string — Your unique API key for authentication. This key is required in the header of all API requests, to authenticate your account and access Anthropic's services. Get your API key through the [Console](https://console.anthropic.com/settings/keys). Each key is scoped to a Workspace.
- `anthropic-workspace-id` string

## Response `200`

    - `expires_at` string, date-time, nullable — RFC 3339 datetime string representing when the file will expire and become unavailable for download. Null if the file does not expire. For files uploaded with `expires_in_seconds`, this is the upload time plus that value.
