## Which one, for what

### 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:
- Schema & documentation, 70 against 51
- Agent ergonomics, 64 against 58

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

### 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 30
- Maintenance & community, 80 against 30

Also in its favour:
- Open source

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

## Verdicts

**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.

**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

### 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

### 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
