## 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 locus-property-tax-appeal-window-scan-dfbc3a76 -d '<json body>'
```

Example prompt: Can you scan public records and check the property tax appeal window for 123 Main Street in New York state — locality nyc_class1 — with a notice date of 2025-01-15?

## When to prefer this

Use this endpoint when you need to quickly determine property tax appeal eligibility windows and scan public-record status for a specific address, particularly in NYC (class 1 or other), Nassau, or Philadelphia jurisdictions. Prefer this over generic property data APIs when the specific goal is understanding appeal deadlines, open record questions, and parcel-level tax rules rather than property valuation or transaction history.

## Known failure modes

- Missing required 'state' or 'address' field returns a validation error
- Invalid date format for noticeDate returns a schema error
- Unsupported locality value outside the enum returns a 400 error
- Address not found in public records returns an empty records array with caveats
- Network timeout for slow jurisdictions may return incomplete data

## How this service works

Cited property-value appeal deadline arithmetic for a covered state. Perfect for: 'appeal deadline from my notice date', 'property-tax protest window'. Returns the rule, statute, source, computed dates when inputs support them, caveats, and verify-next. Never advice to appeal. Charge-free when the state/locality is not covered.

## Output

A JSON object containing a report ID, generation timestamp, a list of public-record findings (records array), and caveats explaining limitations or data gaps — indicating which questions are answered, which remain open, and what to verify next.
