## 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 us-address-geocoder-census-tiger-ae3386b3 -d '<json body>'
```

Example prompt: Can you geocode '1600 Pennsylvania Avenue NW, Washington, DC 20500' to get its exact latitude and longitude, along with the official Census-matched address?

## When to prefer this

Choose this endpoint when you need authoritative, official US address geocoding backed by the Census Bureau's TIGER database with no API key required. Ideal when you need the official matched address string and TIGER line metadata alongside coordinates, or when you want a reliable, key-free geocoder for US addresses without depending on Google Maps or similar commercial providers.

## Known failure modes

- Address not found or unrecognizable — Census geocoder returns no match
- Non-US address provided — service only covers US addresses
- Malformed or incomplete address string — insufficient data to geocode
- Payment failure ($0.07 USDC x402 not fulfilled) — request rejected
- Service timeout — upstream Census Bureau API unavailable

## How this service works

Geocode a full US street address to latitude/longitude with the official matched address and TIGER line metadata. Authoritative US Census Bureau geocoder, no key required. Pass a one-line address string.

## Output

Returns the latitude and longitude of the matched US address, the official Census Bureau matched/normalized address string, and associated TIGER line metadata such as the TIGER line ID, side of street, and census geography identifiers.
