## 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-address-coordinates-census-geocoder-4e4a3e75 -d '<json body>'
```

Example prompt: Can you get the latitude and longitude coordinates for 4600 Silver Hill Rd, Washington, DC 20233 using the Census geocoder?

## When to prefer this

Choose this endpoint when you need authoritative, government-sourced geocoding for U.S. addresses at very low cost ($0.01/call). It is ideal for domestic U.S. address geocoding where Census Bureau coverage (all 50 states, Puerto Rico, and U.S. Island Areas) is sufficient. Prefer it over commercial geocoders when budget sensitivity is high and international address support is not required.

## Known failure modes

- Address not found in Census database — returns empty or null coordinates
- Non-U.S. address provided — service only covers U.S., Puerto Rico, and Island Areas
- Malformed address string — ambiguous or incomplete address may fail to geocode
- Network or upstream Census API timeout — service temporarily unavailable
