Create Batch, Poll, and Retrieve Results

Create Batch, Poll, and Retrieve Results

Create a message batch, wait for it to finish, and pull the results.

1. Create a new message batch from the supplied individual requests. The batch begins processing immediately.
2. Retrieve the current status of the batch. Branch back to poll again while it is still in progress, or continue once processing has ended.
3. Download the JSONL results stream for the completed batch. Each line is a JSON object holding one request's result, keyed by custom_id.

What you'll need to have ready

• apiKey: A valid Anthropic API key sent in the x-api-key header.
• model: Default model id referenced by the documentation for the batch requests.
• requests: The array of individual batch requests, each with a custom_id and a params object (model, max_tokens, messages).
