## 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 30
- Schema & documentation, 86 against 70
- Security & auth, 71 against 45
- Maintenance & community, 40 against 30
- Transparency & trust, 78 against 55

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

### Invofox (D)

Good for: Teams that process a known set of business documents (invoices, payslips, bank statements, mortgage forms) at volume and can receive webhooks.

Ahead on:
- Payments & pricing, 30 against 20

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

Watch for: No status page found. status.invofox.com does not resolve, and neither the site nor the docs link to one

## 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.

**Invofox.** Three public OpenAPI 3.1 files, llms.txt and Markdown docs describe an asynchronous upload and webhook flow, and the free plan covers 500 pages without a card. No status page, rate limit numbers, changelog or official SDK were found, and documents are retained by default, with zero retention limited to Scale and Enterprise.

## 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

### Invofox

1. Ask the owner for an API key and the Document Type id or alias from app.invofox.com. No API endpoint lists Document Types
2. Upload with POST /v1/ingest/uploads as multipart, with `info` as a JSON string. Send `"useClassifier": true` in place of `type` to have the type detected
3. Expect 404 from GET /documents/{id} for the first seconds. Poll from 5 seconds with doubling, and stop at approved, pendingCorrection or discarded
4. Handle the `file.rejected` webhook or check the import. A rejected file never produces a document, so polling the document waits indefinitely
5. Do not retry an upload blindly. There is no idempotency key, so send your own id in `clientData` and look it up with `filter` first
