## 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-report-c5d4f375 -d '<json body>'
```

Example prompt: Pull up the official government property tax records for 742 Evergreen Terrace, Springfield, IL 62704 — I want everything cited to the source.

## When to prefer this

Use this endpoint when you need property tax data specifically, with government-source citations, for a U.S. address. It is the right choice when an agent needs verified, authoritative tax assessment records rather than estimated or aggregated third-party data. Prefer this over general property lookup tools when source traceability and official citation matter (e.g., due diligence, legal, or investment research).

## Known failure modes

- Address not found or outside U.S. coverage — empty records array returned
- ZIP code provided without street address yields lower-resolution parcel data
- Ambiguous address string may match wrong parcel — full street address recommended
- Government source temporarily unavailable — may result in partial records or caveat flags
- Invalid or malformed address/ZIP input returns error response

## How this service works

Verified residential US property record for one street address: assessed value, actual annual property tax, 5yr tax history, effective rate, deed/transfer history, and an owner-occupied (homestead-proxy) signal. Sourced from RentCast (county assessor + recorder records); not an official bill or valuation; never owner names/mailing. Commercial/uncovered addresses return a free charge-free diagnostic. npx @velinussage/locus-agent-skill add.

## Output

A JSON object containing property tax records for the given U.S. address or ZIP code, each record cited to its originating government source, along with a generation timestamp, unique report ID, and any applicable caveats about data coverage or availability.
