Document Understanding API guide
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
For Document Understanding modern projects, a single per-page charge covers all REST API operations against that page:
| Licensing model | Charge per page |
|---|---|
| Unified Pricing | 0.2 Platform Units |
| Flex Plan | 1 AI unit |
The per-page charge applies regardless of which API operations you call. The same charge covers any one of — or any combination of — the following:
- Digitization only
- Classification only
- Extraction only
- A full digitize → classify → extract pipeline (with optional validation)
Calling multiple operations on the same page does not multiply 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 |
Classification charges are capped at a maximum of 1 Platform Unit (or 5 AI units) per document.
