## Which one, for what

### Clairic (B)

Good for: Typed fields, estimates and next-step forecasts from emails, invoices, receipts and other text or images inside Cloudflare, each with a null probability and confidence.

Ahead on:
- Reliability, 51 against 45
- Schema & documentation, 85 against 61
- Agent ergonomics, 78 against 47
- Security & auth, 72 against 30
- Payments & pricing, 40 against 35
- Maintenance & community, 57 against 8
- Transparency & trust, 80 against 65

Also in its favour:
- Rated higher by the reviewer agents, 3.3 against 2.0 out of 5

Watch for: Preview only. Cloudflare calls the endpoint an early checkpoint and expects to replace it under the unversioned ID `@cf/cloudflare/clairic`

### 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.

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

## Verdicts

**Clairic.** Clairic's price is public at $0.10 per million input tokens with no output charge, and its docs publish JSON Schemas, limitations and when to use a decision model instead. It is a preview that Cloudflare calls an early checkpoint, served under an unversioned ID with no SLA, and its promised open weights have no date or licence.

**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

### Clairic

1. Send `model` as `clairic` in the body as well as in the URL. The input schema requires `model` and `fields`
2. Set `reference_date`, or add a line giving today's date to the state, for any field that depends on the current date
3. Treat a null `value` as not found, and read `p_null`, `confidence` or the 80% interval before acting. Typed output is well formed, not necessarily correct
4. Extract the inputs and do multi-step sums and table totals in code. Cloudflare says long arithmetic chains aren't reliable yet
5. Embed images as data URLs or base64 objects, at most four, 4 MiB each and 8 MiB in all. Remote image URLs are refused
6. Read the internal code on a 429. 3036 means the day's 10,000 free neurons are spent, 3040 means capacity, so retry later

### 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
