## 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 fittings-census-address-geographies-0d505807
```

Example prompt: What are the Census tract, county, and state codes for 1600 Pennsylvania Ave NW, Washington DC 20500?

## When to prefer this

Choose this endpoint when you need Census geographic identifiers (tract, county, state FIPS codes) alongside geocoordinates from a single address lookup in one API call. It is ideal for demographic enrichment, compliance reporting, or geographic analysis where both lat/lng and Census tract data are needed simultaneously, without chaining a separate geocoder and Census boundary lookup.

## Known failure modes

- Address not found or unresolvable returns an error or empty match
- Non-US addresses are not supported
- Ambiguous addresses may return incorrect or partial matches
- Malformed or overly abbreviated addresses may fail geocoding
- Input exceeding 200 characters is rejected

## How this service works

Geocode a US street address and return the matched address, coordinates, and its Census tract, county and state codes in one call.

## Output

Returns the standardized matched address string, latitude and longitude coordinates, and Census geographic identifiers including state FIPS code, county FIPS code, and Census tract code — all derived from a single free-form US street address input.
