## Which one, for what

### 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:
- Payments & pricing, 35 against 30
- Transparency & trust, 65 against 47

Also in its favour:
- Free to start without a card

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

### OpenDocRouter (C)

Good for: Agents that need page-level markdown from PDFs and images and want to choose or compare models on price and published benchmark scores with one key.

Ahead on:
- Schema & documentation, 85 against 61
- Agent ergonomics, 84 against 47
- Security & auth, 40 against 30
- Maintenance & community, 65 against 8

Watch for: Launched on 7 October 2026. The domain was registered on 23 September 2026 and both SDKs have one release, 1.0.0

## Verdicts

**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.

**OpenDocRouter.** One endpoint reaches 11 parsing models, each with a dated recipe version, a published token price and a ParseBench score, and failed pages aren't charged. The service launched on 7 October 2026, so it has no status page, incident history, SLA or changelog yet, and no key scopes were found in the reviewed documentation.

## Before you call either

### 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

### OpenDocRouter

1. Call `GET /v1/models` first, which needs no key, and choose a model by `avg_charge_per_page_usd` and its ParseBench scores. Send its `id` as `model`
2. Send `cache: true` on any request you might repeat. Without it the markdown exists only in the POST response and a resend is charged as a new request
3. Raise the SDK timeout above its 60-second default for sync parses. Pages can run for 270 seconds and the SDKs retry a timed-out request twice
4. Check every page's `status` before using its markdown. A 200 can be `partial`, and failed pages can be resent alone with `pages`
5. Treat 402 as final until credit is added. The hold is the model's maximum charge per page times the page count, and `GET /v1/credits` shows `available_usd`
