Authorizations

​
Authorization
string
header
required

Body

application/json

JSON request to create a parse task

​
file
string
required

The file to be parsed. Supported inputs:

  • ch://files/{file_id}: Reference to an existing file. Upload via the Files API
  • http(s)://...: Remote URL to fetch
  • data:*;base64,... or raw base64 string
​
chunk_processing
object

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

​
error_handling
enum<string>
default:Fail

Controls how errors are handled during processing:

  • Fail: Stops processing and fails the task when any error occurs
  • Continue: Attempts to continue processing despite non-critical errors (eg. LLM refusals etc.)
Available options:
Fail,
Continue
​
llm_processing
object

Controls the LLM used for the task.

​
ocr_strategy
enum<string>
default:All

Controls the Optical Character Recognition (OCR) strategy.

  • All: Processes all pages with OCR. (Latency penalty: ~0.5 seconds per page)
  • Auto: Selectively applies OCR only to pages with missing or low-quality text. When text layer is present the bounding boxes from the text layer are used.
Available options:
All,
Auto
​
pipeline
enum<string>
default:Azure
Available options:
Azure,
Chunkr
​
segment_processing
object | null

Configuration for how each document segment is processed and formatted.

Each segment has sensible defaults, but you can override specific settings:

  • format: Output as Html or Markdown
  • strategy: Auto (rule-based), LLM (AI-generated), or Ignore (skip)
  • crop_image: Whether to crop images to segment bounds
  • extended_context: Use full page as context for LLM processing
  • description: Generate descriptions for segments

Defaults per segment type: Check the documentation for more details.

Only specify the fields you want to change - everything else uses the defaults.

​
segmentation_strategy
enum<string>
default:LayoutAnalysis

Controls the segmentation strategy:

  • LayoutAnalysis: Analyzes pages for layout elements (e.g., Table, Picture, Formula, etc.) using bounding boxes. Provides fine-grained segmentation and better chunking.
  • Page: Treats each page as a single segment. Faster processing, but without layout element detection and only simple chunking.
Available options:
LayoutAnalysis,
Page
​
expires_in
integer | null

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

​
file_name
string | null

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

Response

Task created successfully.

object | null

The processed results of a document parsing task

​
started_at
string<date-time> | null
