## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fns-npd-self-employed-status-checker-russia-de2de143
```

Example prompt: Can you check whether INN 771234567890 is registered as a self-employed NPD payer with the Russian Federal Tax Service?

## When to prefer this

Use this endpoint when you need to verify a Russian individual's self-employed (samozanyatiy) status in real time against the official FNS registry, particularly before processing payments to contractors or validating NPD invoices. It is the only low-cost ($0.01) programmatic path to the FNS statusnpd service available via x402 micropayment.

## Known failure modes

- Invalid INN format (not 10 or 12 digits) — likely returns validation error
- INN not found in FNS database — returns is_npd_payer: false with explanatory message
- FNS upstream service unavailable — may return timeout or 5xx error
- Malformed request body — missing required 'inn' field returns 400-level error
