## 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 61
- Agent ergonomics, 64 against 47
- Security & auth, 45 against 30
- Maintenance & community, 30 against 8

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

### Nanonets API + MCP (E)

Good for: A team that wants schema-shaped JSON from mixed documents and is happy to sort out the two API generations.

Ahead on:
- Reliability, 45 against 30
- Payments & pricing, 35 against 30
- Transparency & trust, 65 against 55

Watch for: No public changelog and no dated release in the last 90 days

## 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.

**Nanonets API + MCP.** Extraction API returns Markdown, CSV or JSON, with named fields or a JSON schema. No public changelog and no dated release in the last 90 days.

## 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

### Nanonets API + MCP

1. Use the extraction API at `extraction-api.nanonets.com`, not `app.nanonets.com`, unless you already have a trained model
2. Pass a JSON schema in `json_options` when downstream code needs fixed field names
3. Use the async extract endpoints for long documents and poll `/api/v1/extract/results/{record_id}`
4. On a 429, wait 30 seconds and double the delay each retry
5. Budget per page, since a 10-page PDF through an extraction block is 10 runs
