## 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 suverse-govhub-cms-open-payments-078488b2 -d '<json body>'
```

Example prompt: Pull up the CMS Open Payments records for physician NPI 1234567890 for the year 2022 — I want to see what pharmaceutical or medical device companies paid them.

## When to prefer this

Use this endpoint when you need structured, programmatic access to CMS Open Payments data for a specific physician by NPI without scraping the CMS website directly. Ideal for compliance workflows, conflict-of-interest checks, healthcare research, and investigative journalism tooling. Prefer this over direct CMS API calls when pay-per-call micropayment access via x402 is acceptable and you want a managed gateway with predictable pricing.

## Known failure modes

- Invalid or non-existent NPI returns empty results or error
- Year outside available CMS data range returns no records
- Malformed NPI string causes validation error
- Rate limiting or upstream CMS API unavailability causes timeout
- Payment data not yet published for very recent years
