## 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 foundry-postal-code-lookup-a71adb83 -d '<json body>'
```

Example prompt: What city, state, and coordinates does ZIP code 90210 belong to in the US?

## When to prefer this

Use this endpoint when you need lightweight postal-code-to-location resolution (city, state, coordinates) for 60+ countries without requiring a full geocoding pipeline. It is ideal for address enrichment, form validation, and geolocation from ZIP/postal codes when you already have the country code. Prefer a full geocoding API if you need street-level address parsing or reverse geocoding from coordinates.

## Known failure modes

- Invalid or non-existent postal code returns empty places array
- Unsupported country code may yield no results
- Malformed input (missing country or code) may return an error
- Network timeout on Render.com cold start for infrequently called endpoints
