## Which one, for what

### 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 27
- Schema & documentation, 86 against 51
- Agent ergonomics, 64 against 58
- Security & auth, 71 against 42
- Transparency & trust, 78 against 51

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

### Unstructured API + MCP (D)

Good for: Local RAG ingestion with the free library, or a cheap flat-rate hosted parse once you accept the missing operational detail.

Ahead on:
- Payments & pricing, 40 against 20
- Maintenance & community, 80 against 40

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

Watch for: No status page, no published rate limits and no SLA

## Verdicts

**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.

**Unstructured API + MCP.** Apache-2.0 library partitions 45+ file types locally at no cost, tagged 11 times since 3 July. No status page, no published rate limits and no SLA.

## Before you call either

### 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

### Unstructured API + MCP

1. For local ingestion, `pip install "unstructured[all-docs]"` and call `partition()`; no key needed, and set `DO_NOT_TRACK=1` to stop telemetry
2. Transform returns 202 with a Location header for long parses; poll it, then pass the parse `id` as `parse_id` to Extract
3. Uploaded files expire after 24 hours; keep the original and re-upload on a 404
4. Treat 409 `parse_expired` and 410 `result_expired` as a signal to rerun the parse, not to retry
5. Check for an existing job ID before resubmitting, since there's no idempotency key
