--- title: List Files url: https://platform.claude.com/docs/en/api/java/beta/files/list --- # List Files `FileListPage beta().files().list(params = FileListParams.none(), requestOptions = RequestOptions.none())` **GET** `/v1/files` List Files ## Parameters - `FileListParams params` - `Optional> ids` (query parameter) 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. - `Optional limit` (query parameter) Number of items to return per page. Defaults to `20`. Ranges from `1` to `1000`. minimum: 1, maximum: 1000 - `Optional page` (query parameter) Opaque page cursor returned in a prior list response's `next_page`. Prefixed `page_`. - `Optional scopeId` (query parameter) Filter by scope ID. Only returns files associated with the specified scope (e.g., a session ID). - `Optional> betas` (header parameter) Optional header to specify the beta version(s) you want to use. - `MESSAGE_BATCHES_2024_09_24("message-batches-2024-09-24")` - `PROMPT_CACHING_2024_07_31("prompt-caching-2024-07-31")` - `COMPUTER_USE_2024_10_22("computer-use-2024-10-22")` - `COMPUTER_USE_2025_01_24("computer-use-2025-01-24")` - `PDFS_2024_09_25("pdfs-2024-09-25")` - `TOKEN_COUNTING_2024_11_01("token-counting-2024-11-01")` - `TOKEN_EFFICIENT_TOOLS_2025_02_19("token-efficient-tools-2025-02-19")` - `OUTPUT_128K_2025_02_19("output-128k-2025-02-19")` - `FILES_API_2025_04_14("files-api-2025-04-14")` - `MCP_CLIENT_2025_04_04("mcp-client-2025-04-04")` - `MCP_CLIENT_2025_11_20("mcp-client-2025-11-20")` - `DEV_FULL_THINKING_2025_05_14("dev-full-thinking-2025-05-14")` - `INTERLEAVED_THINKING_2025_05_14("interleaved-thinking-2025-05-14")` - `CODE_EXECUTION_2025_05_22("code-execution-2025-05-22")` - `EXTENDED_CACHE_TTL_2025_04_11("extended-cache-ttl-2025-04-11")` - `CONTEXT_1M_2025_08_07("context-1m-2025-08-07")` - `CONTEXT_MANAGEMENT_2025_06_27("context-management-2025-06-27")` - `MODEL_CONTEXT_WINDOW_EXCEEDED_2025_08_26("model-context-window-exceeded-2025-08-26")` - `SKILLS_2025_10_02("skills-2025-10-02")` - `FAST_MODE_2026_02_01("fast-mode-2026-02-01")` - `OUTPUT_300K_2026_03_24("output-300k-2026-03-24")` - `USER_PROFILES_2026_03_24("user-profiles-2026-03-24")` - `USER_PROFILES_2026_08_18("user-profiles-2026-08-18")` - `USER_PROFILES_2026_09_04("user-profiles-2026-09-04")` - `ADVISOR_TOOL_2026_03_01("advisor-tool-2026-03-01")` - `MANAGED_AGENTS_2026_04_01("managed-agents-2026-04-01")` - `CACHE_DIAGNOSIS_2026_04_07("cache-diagnosis-2026-04-07")` - `DREAMING_2026_04_21("dreaming-2026-04-21")` - `THINKING_TOKEN_COUNT_2026_05_13("thinking-token-count-2026-05-13")` - `SERVER_SIDE_FALLBACK_2026_06_01("server-side-fallback-2026-06-01")` - `SERVER_SIDE_FALLBACK_2026_07_01("server-side-fallback-2026-07-01")` - `FALLBACK_CREDIT_2026_06_01("fallback-credit-2026-06-01")` - `FALLBACK_CREDIT_2026_07_01("fallback-credit-2026-07-01")` - `AGENT_MEMORY_2026_07_22("agent-memory-2026-07-22")` - `MID_CONVERSATION_TOOL_CHANGES_2026_07_01("mid-conversation-tool-changes-2026-07-01")` - `COMPACT_2026_01_12("compact-2026-01-12")` - `COMPUTER_USE_2025_11_24("computer-use-2025-11-24")` - `MCP_TUNNELS_2026_06_22("mcp-tunnels-2026-06-22")` - `STRUCTURED_OUTPUTS_2025_11_13("structured-outputs-2025-11-13")` - `TASK_BUDGETS_2026_03_13("task-budgets-2026-03-13")` - `THINKING_DISPLAY_UPDATES_2026_08_18("thinking-display-updates-2026-08-18")` - `CE_USER_MANAGEMENT_2026_07_13("ce-user-management-2026-07-13")` - `MID_CONVERSATION_OUTPUT_CONFIG_2026_07_01("mid-conversation-output-config-2026-07-01")` - `THINKING_BINDING_CONTROLS_2026_08_01("thinking-binding-controls-2026-08-01")` - `MID_CONVERSATION_SYSTEM_CLEAR_AT_2026_08_21("mid-conversation-system-clear-at-2026-08-21")` - `COMPACT_2026_09_04("compact-2026-09-04")` - `INLINE_TOOLS_2026_09_15("inline-tools-2026-09-15")` - `MCP_CLIENT_2026_09_15("mcp-client-2026-09-15")` - `CE_PLUGINS_2026_09_01("ce-plugins-2026-09-01")` - `SPEND_LIMIT_READS_2026_09_26("spend-limit-reads-2026-09-26")` - `TELEMETRY_DESTINATIONS_2026_08_11("telemetry-destinations-2026-08-11")` - `Optional workspaceId` (header parameter) Optional header to select the Workspace for this request.

For files, this is always `"file"`. - `String id` Unique object identifier. The format and length of IDs may change over time. - `LocalDateTime createdAt` RFC 3339 datetime string representing when the file was created. format: date-time - `String filename` Original filename of the uploaded file. minLength: 1, maxLength: 500 - `String mimeType` MIME type of the file. minLength: 1, maxLength: 255 - `long sizeBytes` Size of the file in bytes. minimum: 0 - `Optional downloadable` Whether the file can be downloaded. - `Optional expiresAt` 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. format: date-time - `Optional scope` The scope of this file, indicating the context in which it was created (e.g., a session). - `JsonValue type = "session"` The type of scope (e.g., `"session"`). - `String id` The ID of the scoping resource (e.g., the session ID). ## Example ```java package com.anthropic.example; import com.anthropic.client.AnthropicClient; import com.anthropic.client.okhttp.AnthropicOkHttpClient; import com.anthropic.models.beta.files.FileListPage; import com.anthropic.models.beta.files.FileListParams; public final class Main { private Main() {} public static void main(String[] args) { AnthropicClient client = AnthropicOkHttpClient.fromEnv(); FileListPage page = client.beta().files().list(); } } ``` ### Response (200) ```json { "data": [ { "id": "file_011CNha8iCJcU1wXNR6q4V8w", "created_at": "2025-04-15T18:37:24.100435Z", "filename": "document.pdf", "mime_type": "application/pdf", "size_bytes": 102400, "type": "file", "downloadable": false, "expires_at": "2025-05-15T18:37:24.100435Z", "scope": { "id": "id", "type": "session" } } ], "next_page": "next_page" } ```
