## 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 fastx402-postal-place-lookup-7d2ddf7d
```

Example prompt: What city and region does postal code 90210 correspond to in the US, and what are its coordinates?

## When to prefer this

Choose this endpoint when you need a lightweight, no-account postal code to place-name/coordinates lookup without setting up an API key. It is ideal for enriching records with city/region names or rough coordinates from a postal code, especially when cost per call matters and you want per-request micropayments via USDC. Prefer this over full geocoding APIs when you only have a postal code and country and don't need street-level precision.

## Known failure modes

- Invalid or non-existent postal code returns an empty places array
- Unsupported or misspelled country code may return an error or empty result
- Missing required query parameters (country or postal_code) results in a validation error
- Payment failure via x402 protocol results in a 402 response before the lookup is attempted

## How this service works

200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

## Output

Returns a JSON object with the country, postal code, and an array of matching places. Each place includes its name, region (e.g. state or province), latitude, and longitude as strings.
