## 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 npi-provider-verification-8b3c24eb
```

Example prompt: Can you verify whether NPI number 1234567890 is valid and tell me what specialty and provider type are associated with it?

## When to prefer this

Use this endpoint when you need a pay-per-call, low-cost NPI lookup without committing to a subscription-based credentialing service. Ideal for lightweight agent workflows performing spot checks on individual providers, or when processing small volumes of NPI verifications with USDC micropayments via x402.

## Known failure modes

- Invalid or non-existent NPI returns a not-found error
- Malformed NPI (not 10 digits) may return a validation error
- NPI registry may be temporarily unavailable causing upstream errors
- Deactivated NPIs may return a record with inactive status rather than an error
