## 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-context-688ce2c1 -d '<json body>'
```

Example prompt: What's the effective property tax rate context for 742 Evergreen Terrace, Springfield, IL — is the tax burden typical for that ZIP and county compared to the state median?

## When to prefer this

Use this endpoint when you need to contextualize a property tax bill or assess the typical tax burden for a US location at ZIP, county, or state level using authoritative ACS data. Prefer this over general web search when you need structured, comparable rate benchmarks. Not suitable when you need the specific assessed value or actual tax bill for an individual parcel — use a parcel-record endpoint for that.

## Known failure modes

- Address cannot be geocoded or matched to a US jurisdiction — returns error or null coverage
- Input address is outside the United States — no data available
- ZIP or county not covered in ACS 2023 release — partial or null response
- Malformed coordinates outside valid US range — validation error
- Missing both address and coordinates — request rejected

## How this service works

Property tax burden context: ACS 2023 median real-estate taxes paid, median home value, and the effective rate they imply at ZIP, county, and state, with the Lincoln Institute 50-state study linked. Perfect for: 'effective property tax rate here', 'is this tax bill typical for the county'. Locality estimate, not this parcel's bill. National. Free at /tools/call.

## Output

Returns median real-estate taxes paid, median home value, and the implied effective tax rate for the ZIP code, county, and state corresponding to the input address or coordinates, sourced from ACS 2023 data. Also includes a link to the Lincoln Institute 50-state study. This is a locality-level statistical estimate, not the specific parcel's actual tax bill.
