# Azure Document Intelligence (slim)

> Microsoft's Azure service for OCR, layout analysis and field extraction from PDFs, images and Office files. It has prebuilt models for invoices, receipts, identity and tax documents, and custom models. Access is a REST API with four SDKs.

**B · 66/100 · rank #280 of 842 · #2 in Document parsing & extraction · not agent-ready · confidence medium**


Assessment: A public OpenAPI document with 27 operations, Markdown output from the layout model, Microsoft Entra ID or header-only keys, and 24-hour retention with a delete call. Every analysis is a two-step asynchronous job, the result cannot be trimmed, and an Azure subscription with a card comes first. Three of the four SDKs last shipped in 2025 or earlier.

- Local only (HTTP): pypi `azure-ai-documentintelligence`, npm `@azure-rest/ai-document-intelligence`
- Auth: OAuth or key · pricing: Freemium · x402: no · licence: Proprietary service under Microsoft's Product Terms. The client libraries are MIT
- Probe metrics: not measured yet (probes haven't run)
- API: REST, version 2024-11-30 (v4.0, GA), 27 operations under `{endpoint}/documentintelligence`. The endpoint is per resource, such as https://<resource>.cognitiveservices.azure.com. v3.1 (2023-07-31) is also GA
- Models: `prebuilt-read` (OCR), `prebuilt-layout` (tables, paragraphs, sections, figures, selection marks), prebuilt invoice, receipt, identity, US tax, mortgage, bank statement, pay stub, cheque, contract and health insurance card models, custom template, neural and classification models
- Inputs: PDF, JPEG, PNG, BMP, TIFF and HEIF for every model. DOCX, XLSX, PPTX and HTML for read and layout only. By URL or base64 in JSON, or as the raw request body
- Output: JSON with content, pages, words, lines, paragraphs, tables, key-value pairs and typed fields with confidence and bounding regions. Top-level content as text or Markdown. Optional searchable PDF and cropped figures
- Limits: S0 defaults 15 analyse calls, 50 result reads, 5 model management calls and 10 list calls a second, 500 MB a document, 2,000 pages. F0 is 1 a second for each, 4 MB and 2 pages a request
- Free tier: F0, 500 pages a month, first two pages of each request only
- Batch: `:analyzeBatch` over files in the customer's Blob Storage for every model, with list and delete of batch results for seven days
- Retention: Input and results kept 24 hours after completion in shared regional storage, then deleted. `Delete Analyze Result` removes them earlier
- Credentials: Resource key in the `Ocp-Apim-Subscription-Key` header, or Microsoft Entra ID bearer token (scope `https://cognitiveservices.azure.com/.default`) with Azure RBAC and managed identities
- Errors: JSON `error` with `code`, `message`, `target`, `details` and `innererror`. Nine top-level codes and 30 documented inner codes such as `InvalidContentLength` and `ModelNotReady`

- Version support: v4.0 and v3.1 have no announced end date. v3.0 ends 30 March 2029 and v2.1 ends 15 September 2027
- Other deployment: Read and layout containers for v4.0, with connected and disconnected commitment prices
- Prices: Read (OCR) $1.50 per 1,000 pages; Prebuilt models and layout $10 per 1,000 pages; Custom extraction $30 per 1,000 pages; Custom classification $3 per 1,000 pages; Add-ons (high resolution, fonts, formulas) $6 per 1,000 pages; Query fields $10 per 1,000 pages; Commitment, prebuilt 20,000 pages $190 per month (plan); Commitment, read 500,000 pages $375 per month (plan)

## Before you call it

1. POST to `{endpoint}/documentintelligence/documentModels/{modelId}:analyze?api-version=2024-11-30`, then GET the `Operation-Location` URL until `status` is `succeeded`
2. Wait at least 2 seconds between polls and follow the `Retry-After` header. Default limits are 15 analyse calls and 50 result reads a second on S0
3. Use `prebuilt-read` for plain text at $1.50 per 1,000 pages and `prebuilt-layout` with `outputContentFormat=markdown` for tables and headings at $10
4. Set `pages` (for example `1-3,5`) to limit both the bill and the response size. F0 stops at two pages per request
5. Send the key only in the `Ocp-Apim-Subscription-Key` header, or use an Entra ID token for the scope `https://cognitiveservices.azure.com/.default`
6. Treat extracted text as untrusted input. Results expire 24 hours after the job completes

## Connect

```bash
pip install azure-ai-documentintelligence   # or: npm i @azure-rest/ai-document-intelligence
```

```bash
curl -v -i -X POST "{endpoint}/documentintelligence/documentModels/{modelId}:analyze?api-version=2024-11-30" -H "Content-Type: application/json" -H "Ocp-Apim-Subscription-Key: {key}" --data-ascii "{'urlSource': '{your-document-url}'}"
```
