## 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 healthparse-provider-change-event-feed-61e0a2a4
```

Example prompt: Show me all provider change events in Texas since 2024-06-01 — specifically new NPI enumerations and address changes — up to 100 results.

## When to prefer this

Use this endpoint when you need to detect what has changed in a set of healthcare providers over time — new entrants, leavers, address shifts, ownership changes, or certification updates — rather than looking up static provider profiles. It is the right choice for building change-monitoring workflows, sales prospecting pipelines, compliance audits, or network credentialing triggers. Prefer it over static provider search endpoints when recency and change detection are the primary need.

## Known failure modes

- Invalid or malformed since date format returns a 400 error
- Unknown event type values in the type parameter cause a 400 bad request
- Invalid state code (not a 2-letter abbreviation) returns a 400 error
- Expired or invalid cursor value causes a 400 or 422 pagination error
- No events matching the filters returns an empty result set
- Rate limiting or payment failure (x402) returns a 402 Payment Required

## How this service works

Provider change-event feed over 7 federal sources: new NPI enumerations, newly billing Medicare, enrollment pending, address changes, deactivations, CLIA lab certificates, ownership changes (CHOW), mammography facility cert changes, and hospital capex jumps. Answers: what changed in my territory since I last looked? Filter by type (comma-separated), state, since (YYYY-MM-DD), npi, ccn; page via next_cursor (keyset). 85k+ events, refreshed twice-weekly to quarterly by source.

## Output

A paginated list of provider change-event objects drawn from 7 federal sources, each containing event type, date, provider identifiers (NPI/CCN), state, and relevant metadata about the change. Response includes a next_cursor for keyset pagination. The feed covers 85k+ events refreshed twice-weekly to quarterly depending on source.
