​
Overview

This endpoint is part of LemonData’s OpenAI-compatible Batch API. Batch jobs use uploaded JSONL files, run asynchronously, and can return output/error files later.

​
Notes

  • Batch input files must use purpose=batch.
  • completion_window is currently 24h.
  • Output ordering is not guaranteed; always match by custom_id.
  • Streaming is not supported inside batch items.

​
Request / Response

Use the interactive OpenAPI panel above for the exact schema.

​
Operational Tips

  • Use custom_id for idempotent downstream reconciliation.
  • Expect output_file_id and error_file_id only after the worker finalizes the batch.
  • Batch pricing may differ from synchronous pricing because isBatchRequest=true discount rules apply.

​
Anthropic Files API Mode

This same /v1/files route also supports the Anthropic Files API path.
  • Add anthropic-beta: files-api-2025-04-14 to switch the route into Anthropic mode.
  • In Anthropic mode, upload the original file directly and do not send purpose=batch.
  • The returned file_id is bound to the same official Anthropic channel/workspace and should be reused from /v1/messages requests.
  • If you plan to reference the uploaded file from Anthropic message content, keep using Anthropic-native headers (x-api-key, anthropic-version, and the beta header when required).
