## 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 lilambd-signals-country-signal-lookup-304a45af
```

Example prompt: Can you fetch the lilambd signal for Germany — its ISO code is DE?

## When to prefer this

Use this endpoint when you need a lilambd-specific signal or computed output scoped to a single country and can identify it by ISO 3166-1 alpha-2 code. It is a low-cost, per-call lookup suitable for real-time or on-demand queries about individual nations.

## Known failure modes

- Invalid or unrecognized ISO2 country code returns an error or empty result
- Missing path parameter {iso2} causes a 404 or malformed request
- Payment of 0.005 USDC not provided or rejected results in a 402 Payment Required response
- Network or server error returns a 5xx status

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON object containing a computed signal or data output for the specified country. The exact fields depend on lilambd's internal computation, but the response is structured JSON keyed to the requested country.
