Authorizations

​
Authorization
string
header
required

Path Parameters

​
task_id
string
required

Body

application/json

JSON request to update an task

​
chunk_processing
object | null

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

​
error_handling
enum<string> | null

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
​
expires_in
integer | null

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

​
high_resolution
boolean | null

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

​
llm_processing
object | null

Controls the LLM used for the task.

​
ocr_strategy
enum<string> | null

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> | null

Choose the provider whose models will be used for segmentation and OCR. The output will be unified to the Chunkr output format.

Available options:
Azure,
Chunkr
​
segment_processing
object | null

Defines how each segment type is handled when generating the final output.

Each segment uses one of three strategies. The chosen strategy controls:

  • Whether the segment is kept (Auto, LLM) or skipped (Ignore).
  • How the content is produced (rule-based vs. LLM).
  • The output format (Html or Markdown).

Optional flags such as image cropping, extended context, and descriptions further refine behaviour.

Default strategy per segment

  • Title, SectionHeader, Text, ListItem, Caption, Footnote → Auto (Markdown, description off)
  • Table → LLM (HTML, description on)
  • Picture → LLM (Markdown, description off, cropping All)
  • Formula, Page → LLM (Markdown, description off)
  • PageHeader, PageFooter → Ignore (removed from output)

Strategy reference

  • Auto – rule-based content generation.
  • LLM – generate content with an LLM.
  • Ignore – exclude the segment entirely.
​
segmentation_strategy
enum<string> | null

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
