## 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`):

## When to prefer this

Choose this endpoint when you need authoritative, government-sourced geocoding for U.S. addresses at low cost ($0.01/call). It is ideal for operations teams geocoding domestic U.S. addresses where Census Bureau coverage (including Puerto Rico and Island Areas) is sufficient and where you do not require international address support or premium commercial geocoding accuracy.

## Known failure modes

- Address not found in Census Geocoder database — returns no match or empty coordinates
- Non-U.S. address submitted — service only covers U.S., Puerto Rico, and Island Areas
- Malformed or ambiguous address string — may return incorrect or null results
- Address outside coverage area (e.g. international) — not supported
- Payment failure via x402 protocol — call not executed

## How this service works
