Metering and Charging

This page describes how Document Understanding REST API calls are charged. Charging depends on the project type (modern or classic) and the licensing model (Unified Pricing or Flex Plan).

For pricing through activity packages (DocumentUnderstanding.Activities and IntelligentOCR.Activities), see the user-guide pages instead:

• Metering and charging logic (Unified Pricing) — modern projects under Unified Pricing.
• Metering and charging logic (Flex Plan) — modern projects under Flex Plan.
• Metering and charging logic (Classic) — classic projects (activity-based rates).

Modern projects via API

How Document Understanding modern project REST API calls are charged depends on your licensing model.

Flex Plan

REST API calls are charged per operation. You pay only for the operations you call on each page:

Operation	AI units per page
Digitization (including OCR)	0
Classification	0.2
Extraction (with prior classification)	0.8
Extraction (without prior classification)	1

A page that is both classified and extracted is capped at 1 AI unit total. If you call multiple extractors on the same page, each extraction is charged separately.

Unified Pricing

A single per-page charge of 0.2 Platform Units is the standard rate and covers all REST API operations against that page. The same charge covers any one, or any combination, of the following:

• Digitization only.
• Classification only.
• Extraction only.
• A full digitize, classify, and extract pipeline, with optional validation.

Calling multiple operations with the same model does not multiply the charge, whereas calling multiple operations with different models multiplies the charge.

Classic projects via API

For Document Understanding classic projects, REST API calls are charged per capability:

Capability	Unified Pricing	Flex Plan
Digitization	0.04 Platform Units/page	0.2 AI units/page
Extraction	0.2 Platform Units/page	1 AI unit/page
Classification	Applicable per page range — see the table below	Applicable per page range — see the table below

The consumption for Classification is applicable per page range:

Document pages	Unified Pricing	Flex Plan
1-25	0 PU	0 AIU
26-50	0.2 PU	1 AIU
51-75	0.4 PU	2 AIU
76-100	0.6 PU	3 AIU
101-125	0.8 PU	4 AIU
125+	1 PU	5 AIU

Note:

Classification charges are capped at a maximum of 1 Platform Unit (or 5 AI units) per document.
