A split reads the whole parse and costs 1 credit per page (6 with `effort: high`), however many topics you send. By default, the call waits for the job to end. With `async: true`, it returns `202` at once. Read the pages at `GET /split/{split_id}/result`. ## OpenAPI ````yaml /api-reference/v2/openapi.yml post /split openapi: 3.1.0 info: title: Pulse API description: >- Agentic document infrastructure for the enterprise.
