Message Batches API - Anthropic-API | CodeMentor

1When would you use the Batches API instead of regular Messages API calls? — expected answer: async processing of large volumes, 50% cost reduction, non-time-sensitive workloads like bulk evaluation or dataset generationExpertHigh

2What's the max batch size and how do you retrieve results? — expected answer: results come back via a results_url on the batch object; you poll processing_status until it's doneExpertHigh

3What statuses can a batch request have? — succeeded, errored, canceled, expired, and in_progressExpertHigh

4Is the Batches API eligible for Zero Data Retention? — No — batch processing requires 29-day retention for async storage, so it's not ZDR-eligibleExpertHigh
