## 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-ff1e75e6 -d '<json body>'
```

Example prompt: Can you pull up the property appraisal record for HCAD account number 0661340000015 in Harris County — I need the assessed value and owner info.

## When to prefer this

Use this endpoint when you have a specific property account number or identifier and need to retrieve official county appraisal records. Prefer this over address-based search endpoints when you already know the parcel/account ID for a precise, unambiguous lookup. Best for Harris County (HCAD) or Travis County (TCAD) property data in Texas.

## Known failure modes

- Property identifier not found — returns 404 or empty result
- Invalid or malformed account number — returns 400 validation error
- Unsupported county — endpoint may not cover all counties
- Payment failure — x402 payment not processed, returns 402
- Rate limiting or quota exceeded — returns 429

## Output

Returns property appraisal and assessment details for the requested property, including owner information, appraised value, property characteristics, and related tax assessment data from the relevant county appraisal district.
