## 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 x402datasource-com-0ef70583
```

Example prompt: What properties does TCAD show near latitude 30.2672 and longitude -97.7431 in Travis County — I want to see who owns them, their appraised values, and any homestead exemptions.

## When to prefer this

Use this endpoint when you need to discover multiple nearby properties given only a geographic coordinate within Travis County, TX — particularly when you don't have a TCAD account number or address. Prefer it over the TCAD account-number or address-search endpoints when performing proximity analysis, neighborhood comparisons, or geospatial real estate research.

## Known failure modes

- Missing required lat or lng parameters returns a 400 validation error
- Coordinates outside Travis County boundaries may return zero results
- Payment failure or insufficient USDC balance returns a 402 Payment Required error
- Invalid coordinate types (non-numeric) cause schema validation failures
- Very rural coordinates with no nearby parcels return an empty results array

## How this service works

Pay-per-request data API for AI agents. No subscriptions, no API keys — each request is paid using the x402 protocol, settled on-chain. Real-world structured data on demand.

## Output

An array of nearby Travis County properties sorted by distance from the search center, each containing: full address, owner name, TCAD geo_id, legal description, year built, land and improvement square footage, land acreage, price per sqft, market/appraised/assessed/land/improvement values, homestead cap savings, exemptions (homestead, over-65, disabled person, disabled veteran), data year, and distance in meters. Also returns the search center coordinates, result count, and search radius in meters.
