## Which one, for what

### Adobe PDF Services / PDF Extract API (C)

Good for: Teams already on Adobe that want PDF extraction and PDF manipulation on one credential, with EU processing.

Ahead on:
- Maintenance & community, 53 against 40

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: No published paid price, paid use goes through sales

### Azure Document Intelligence (B)

Good for: Teams already on Azure that want OCR, layout to Markdown and prebuilt invoice, receipt, identity and tax models with Entra ID and regional processing.

Ahead on:
- Reliability, 82 against 50
- Schema & documentation, 86 against 80
- Agent ergonomics, 64 against 57
- Security & auth, 71 against 55

Watch for: Every analysis is asynchronous. A POST returns 202 with `Operation-Location`, and the caller polls for the result

## Verdicts

**Adobe PDF Services / PDF Extract API.** Public OpenAPI 3.0.1 spec covering Extract, PDF to Markdown and 20 other operations. No published paid price, paid use goes through sales.

**Azure Document Intelligence.** 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.

## Before you call either

### Adobe PDF Services / PDF Extract API

1. Cache the access token and reuse it until it expires
2. Budget 1 Document Transaction per 5 pages for Extract and PDF to Markdown, so 500 free transactions cover about 2,500 pages
3. Pass `notifiers` with a callback URL instead of polling the job status
4. Use `pdf-services-ew1.adobe.io` when documents must stay in the EU
5. Check `/operation/pdfproperties` first, since copy-protected PDFs fail Extract with DISQUALIFIED_PERMISSIONS

### Azure Document Intelligence

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
