## 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 strale-postal-code-lookup-582f6d00
```

Example prompt: Can you look up the city, state, and timezone for ZIP code 30301 in the US?

## When to prefer this

Use this endpoint when you need reliable, auditable postal code resolution across 27 countries with cryptographic chain hashing for compliance or trust-sensitive workflows. Prefer it over generic geocoding APIs when you need the audit trail, or when operating in non-US markets where coverage matters. Ideal for address enrichment, form validation, and timezone detection pipelines.

## Known failure modes

- Invalid or non-existent postal code returns an error or empty result
- Missing required postal_code parameter returns a 400 validation error
- Unsupported country code may return no data or an error
- Malformed country code (not ISO 2-letter) may cause a validation failure
- Network or service unavailability returns a 5xx error
