## Retrieve Message Batch results

`MessageBatchIndividualResponse messages().batches().resultsStreaming(BatchResultsParamsparams = BatchResultsParams.none(), RequestOptionsrequestOptions = RequestOptions.none())`

**get** `/v1/messages/batches/{message_batch_id}/results`

Streams the results of a Message Batch as a `.jsonl` file.

Each line in the file is a JSON object containing the result of a single request in the Message Batch. Results are not guaranteed to be in the same order as requests. Use the `custom_id` field to match results to requests.

Learn more about the Message Batches API in our [user guide](https://docs.claude.com/en/docs/build-with-claude/batch-processing)

### Parameters

- `BatchResultsParams params`

  - `Optional<String> messageBatchId`

    ID of the Message Batch.

### Returns

- `class MessageBatchIndividualResponse:`

  This is a single line in the response `.jsonl` file and does not represent the response as a whole.

  - `String customId`

    Developer-provided ID created for each request in a Message Batch. Useful for matching results to requests, as results may be given out of request order.

    Must be unique for each request within the Message Batch.

  - `MessageBatchResult result`

    Processing result for this request.

    Contains a Message output if processing was successful, an error response if processing failed, or the reason why processing was not attempted, such as cancellation or expiration.

    - `class MessageBatchSucceededResult:`

      - `Message message`

        - `String id`

          Unique object identifier.

          The format and length of IDs may change over time.

        - `Optional<Container> container`

          Information about the container used in the request (for the code execution tool)

          - `String id`

            Identifier for the container used in this request

          - `LocalDateTime expiresAt`

            The time at which the container will expire.

        - `List<ContentBlock> content`

          Content generated by the model.

          This is an array of content blocks, each of which has a `type` that determines its shape.

          Example:

          ```json
          [{"type": "text", "text": "Hi, I'm Claude."}]
          ```

          If the request input `messages` ended with an `assistant` turn, then the response `content` will continue directly from that last turn. You can use this to constrain the model's output.

          For example, if the input `messages` were:

          ```json
          [
            {"role": "user", "content": "What's the Greek name for Sun? (A) Sol (B) Helios (C) Sun"},
            {"role": "assistant", "content": "The best answer is ("}
          ]
          ```

          Then the response `content` might be:

          ```json
          [{"type": "text", "text": "B)"}]
          ```

          - `class TextBlock:`

            - `Optional<List<TextCitation>> citations`

              Citations supporting the text block.

              The type of citation returned will depend on the type of document being cited. Citing a PDF results in `page_location`, plain text results in `char_location`, and content document results in `content_block_location`.

              - `class CitationCharLocation:`

                - `String citedText`

                - `long documentIndex`

                - `Optional<String> documentTitle`

                - `long endCharIndex`

                - `Optional<String> fileId`

                - `long startCharIndex`

                - `JsonValue; type "char_location"constant`

                  - `CHAR_LOCATION("char_location")`

              - `class CitationPageLocation:`

                - `String citedText`

                - `long documentIndex`

                - `Optional<String> documentTitle`

                - `long endPageNumber`

                - `Optional<String> fileId`

                - `long startPageNumber`

                - `JsonValue; type "page_location"constant`

              - `class CitationContentBlockLocation:`

                - `String citedText`

                  The full text of the cited block range, concatenated.

                  Always equals the contents of `content[start_block_index:end_block_index]` joined together. The text block is the minimal citable unit; this field is never a substring of a single block. Not counted toward output tokens, and not counted toward input tokens when sent back in subsequent turns.

                - `long documentIndex`

                - `Optional<String> documentTitle`

                - `long endBlockIndex`

                  Exclusive 0-based end index of the cited block range in the source's `content` array.

                  Always greater than `start_block_index`; a single-block citation has `end_block_index = start_block_index + 1`.

                - `Optional<String> fileId`

                - `long startBlockIndex`

                  0-based index of the first cited block in the source's `content` array.

                - `JsonValue; type "content_block_location"constant`

                  Always equals the contents of `content[start_block_index:end_block_index]` joined together. The text block is the minimal citable unit; this field is never a substring of a single block. Not counted toward output tokens, and not counted toward input tokens when sent back in subsequent turns.

                - `long endBlockIndex`

                  Exclusive 0-based end index of the cited block range in the source's `content` array.

                  Always greater than `start_block_index`; a single-block citation has `end_block_index = start_block_index + 1`.

                - `long searchResultIndex`

                  0-based index of the cited search result among all `search_result` content blocks in the request, in the order they appear across messages and tool results.

                  Counted separately from `document_index`; server-side web search results are not included in this count.

                - `String source`

                - `long startBlockIndex`

                  0-based index of the first cited block in the source's `content` array.

        - `JsonValue; role "assistant"constant`

          Conversational role of the generated message.

          This will always be `"assistant"`.

          - `ASSISTANT("assistant")`

        - `Optional<RefusalStopDetails> stopDetails`

          Structured information about a refusal.

          - `Optional<Category> category`

            The policy category that triggered the refusal.

            `null` when the refusal doesn't map to a named category.

            - `CYBER("cyber")`

            - `BIO("bio")`

            - `REASONING_EXTRACTION("reasoning_extraction")`

          - `Optional<String> explanation`

            Human-readable explanation of the refusal.

            This text is not guaranteed to be stable. `null` when no explanation is available for the category.

          - `JsonValue; type "refusal"constant`

            - `REFUSAL("refusal")`

        - `Optional<StopReason> stopReason`

          The reason that we stopped.

          This may be one the following values:

          * `"end_turn"`: the model reached a natural stopping point
          * `"max_tokens"`: we exceeded the requested `max_tokens` or the model's maximum
          * `"stop_sequence"`: one of your provided custom `stop_sequences` was generated
          * `"tool_use"`: the model invoked one or more tools
          * `"pause_turn"`: we paused a long-running turn. You may provide the response back as-is in a subsequent request to let the model continue.
          * `"refusal"`: when streaming classifiers intervene to handle potential policy violations

          In non-streaming mode this value is always non-null. In streaming mode, it is null in the `message_start` event and non-null otherwise.

          - `END_TURN("end_turn")`

          - `MAX_TOKENS("max_tokens")`

          - `STOP_SEQUENCE("stop_sequence")`

          - `TOOL_USE("tool_use")`

          - `PAUSE_TURN("pause_turn")`

          - `REFUSAL("refusal")`

        - `Optional<String> stopSequence`

          Which custom stop sequence was generated, if any.

          This value will be a non-null string if one of your custom stop sequences was generated.

        - `JsonValue; type "message"constant`

          Object type.

          For Messages, this is always `"message"`.

          - `MESSAGE("message")`

        - `Usage usage`

          Billing and rate-limit usage.

          Anthropic's API bills and rate-limits by token counts, as tokens represent the underlying cost to our systems.

          Under the hood, the API transforms requests into a format suitable for the model. The model's output then goes through a parsing stage before becoming an API response. As a result, the token counts in `usage` will not match one-to-one with the exact visible content of an API request or response.

          For example, `output_tokens` will be non-zero, even for an empty string response from Claude.

          Total input tokens in a request is the summation of `input_tokens`, `cache_creation_input_tokens`, and `cache_read_input_tokens`.

          - `Optional<CacheCreation> cacheCreation`

            Breakdown of cached tokens by TTL

            - `long ephemeral1hInputTokens`

              The number of input tokens used to create the 1 hour cache entry.

            - `long ephemeral5mInputTokens`

              The number of input tokens used to create the 5 minute cache entry.

          - `Optional<Long> cacheCreationInputTokens`

            The number of input tokens used to create the cache entry.

          - `Optional<Long> cacheReadInputTokens`

            The number of input tokens read from the cache.

          - `Optional<String> inferenceGeo`

            The geographic region where inference was performed for this request.

          - `long inputTokens`

            The number of input tokens which were used.

          - `long outputTokens`

            The number of output tokens which were used.

          - `Optional<OutputTokensDetails> outputTokensDetails`

            Breakdown of output tokens by category.

            `output_tokens` remains the inclusive, authoritative total used for billing.
            This object provides a read-only decomposition for observability — for example,
            how many of the billed output tokens were spent on internal reasoning that may
            have been summarized before being returned to you.

            - `long thinkingTokens`

              Number of output tokens the model generated as internal reasoning, including
              the thinking-block delimiter tokens.

              Reflects the raw reasoning the model produced, not the (possibly shorter)
              summarized thinking text returned in the response body. Computed by
              re-tokenizing the raw reasoning text, so it may differ from the model's exact
              generation count by a small number of tokens. Always ≤ `output_tokens`;
              `output_tokens - thinking_tokens` approximates the non-reasoning output.

          - `Optional<ServerToolUsage> serverToolUse`

            The number of server tool requests.

            - `long webFetchRequests`

              The number of web fetch tool requests.

            - `long webSearchRequests`

              The number of web search tool requests.

          - `Optional<ServiceTier> serviceTier`

            If the request used the priority, standard, or batch tier.

            - `STANDARD("standard")`

            - `PRIORITY("priority")`
