Submit up to 1,000 files for parsing in a single request. Each file is processed as an independent parse run using the same configuration.

Unlike the single Parse File (Async) endpoint, this batch endpoint accepts an inputs array and immediately returns a BatchRun object containing a batch id and a PENDING status. The individual runs are then queued and processed asynchronously.

Monitoring results:

Webhooks (recommended): Subscribe to batch_parse_run.processed and batch_parse_run.failed events. The webhook payload indicates the batch has finished — fetch individual run results using GET /parse_runs?batchId={id}.
Polling: Call GET /batch_runs/{id} to check the overall batch status, and use GET /parse_runs?batchId={id} to retrieve individual run results.

Notes:

inputs must contain between 1 and 1,000 items.
File input supports URLs, Extend file IDs, and raw text strings.

Authentication

AuthorizationBearer

Bearer authentication of the form Bearer <token>, where token is your auth token.

Request

This endpoint expects an object.

inputslist of objectsRequired

An array of inputs to parse. Each item produces one parse run. Must contain between 1 and 1,000 items.

configobjectOptional

Optional parsing configuration applied to every run in this batch. If omitted, default parse settings are used.

priorityintegerOptional1-100Defaults to 50

An optional value used to determine the relative order of runs when rate limiting is in effect. Lower values will be prioritized before higher values.
