## 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-aa024252 -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, county FIPS) tied to a specific address, particularly for compliance, demographic analysis, or operations workflows that require Census-standard geographies. It is the right choice when the downstream use case demands Census-authoritative data rather than commercial geocoders. Prefer alternatives if you need international addresses, high-volume batch geocoding, or additional data like POI or timezone.

## Known failure modes

- Address not found in Census Geocoder – returns no match or empty result for non-US, unrecognized, or malformed addresses
- Missing required fields (street, city, state) may produce null or error response
- Puerto Rico and U.S. Island Areas supported but coverage may be less complete than contiguous US
- PO Box or non-standard address formats may fail to geocode
- Service unavailability if upstream Census Bureau API is down
