Body

application/json

JSON request to create a task

file

string

required

The file to be uploaded. Can be a URL or a base64 encoded file.

chunk_processing

object | null

Controls the setting for the chunking and post-processing of each chunk.

expires_in

integer | null

The number of seconds until task is deleted. Expried tasks can not be updated, polled or accessed via web interface.

file_name

string | null

The name of the file to be uploaded. If not set a name will be generated.

high_resolution

boolean | null

default:

false

Whether to use high-resolution images for cropping and post-processing. (Latency penalty: ~7 seconds per page)

ocr_strategy

enum<string> | null

default:

All

Controls the Optical Character Recognition (OCR) strategy.

All: Processes all pages with OCR. (Latency penalty: ~0.5 seconds per page)

Available options:

All,

Auto

pipeline

enum<string> | null
