## 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 u-s-census-geocoder-parsed-address-census-geographies-47d0d454 -d '<json body>'
```

Example prompt: Can you geocode 4600 Silver Hill Rd, Washington, DC 20233 and give me the Census tract, block, and county FIPS codes for that address?

## When to prefer this

Choose this endpoint when you need official U.S. Census geographic identifiers (tract, block, FIPS codes) tied to a specific address, particularly for demographic enrichment, compliance reporting (e.g. CRA, HMDA), or any workflow requiring authoritative Census boundary matching. It is the right choice for US, Puerto Rico, and Island Areas addresses. Prefer alternatives for international geocoding or when you only need latitude/longitude without Census geographies.

## Known failure modes

- Address not found or ambiguous – geocoder returns no match or multiple candidates
- Address outside coverage area (non-US, non-Puerto Rico, non-Island Areas) – no result returned
- Malformed input (missing street or state) – validation error or empty response
- Geocoder service unavailability – upstream Census API timeout or error
- PO Box or non-deliverable address – may not resolve to a Census block

## How this service works

Parsed address and Census geographies for Agent builders: Parsed address and Census geographies using the U.S. Census Geocoder. Coverage is limited to the United States, Puerto Rico, and U.S. Island Areas.

## Output

Returns parsed address components (standardized street, city, state, ZIP) along with matched U.S. Census geographic identifiers including Census tract, Census block, block group, county FIPS code, and state FIPS code. May also include matched coordinates (latitude/longitude) depending on the geocoder response.
