## 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 pennyapi-regulatory-watch-texas-childcare-monitoring-change-detection-94dde0f1
```

Example prompt: Check PennyAPI Regulatory Watch for any recent changes to Texas HHSC childcare operation number 1677526 — I want to know if there have been any adverse actions or status updates.

## When to prefer this

Use this endpoint when you need to detect and retrieve specific regulatory change events for a known Texas HHSC childcare operation number, particularly for adverse actions, licensing status, or compliance record updates. Prefer this over a general web search when you need structured, machine-readable change history with before/after values and timestamps. It is purpose-built for compliance monitoring workflows involving Texas childcare facilities.

## Known failure modes

- Invalid or non-existent operation number returns empty events array or error
- Operation number with no recorded changes returns event_count_returned of 0
- Malformed operation_number parameter causes 400 Bad Request
- Payment failure (x402) causes 402 Payment Required response
- Upstream HHSC data unavailability may cause stale or missing results
- Limit parameter out of range (below 1 or above 100) causes validation error

## How this service works
