## 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 a lightweight, pay-per-call postal code resolver that works globally — not just for US ZIP codes — and when you need coordinates alongside place name and region. Ideal for agents that need to enrich address data or validate location fields without maintaining a local geocoding database.

## Known failure modes

- Postal code not found: returns found=false with null place and coordinate fields
- Invalid or malformed ZIP code in URL path returns an error or found=false
- Country not supported may return no results
- Rate limiting or payment failure if x402 payment not properly handled
