## How to call it through Zero

```sh
zero fetch --capability lilambd-crossing-water-region-lookup-ac17df35
```

Example prompt: Can you fetch the water data for region ID 'meadow-7' from the lilambd crossing platform?

## When to prefer this

Choose this endpoint when you specifically need water-related data for a named land region from the lilambd experimental platform. It is best suited for creative, generative, or exploratory use cases where loosely structured JSON output is acceptable. Prefer this over geospatial APIs when the goal is experimental computation or artistic data exploration rather than precise hydrological or geographic measurement.

## Known failure modes

- Invalid or unknown region ID returns an error or empty response
- Malformed ID path parameter causes a 400 or 404 error
- Payment failure (x402) blocks access if USDC micropayment is not completed
- Ambiguous or undocumented response schema makes parsing unpredictable
- Region may exist but have no water data, returning null or empty fields

## 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 water-related properties and state data associated with the specified land region ID. The structure is loosely typed and may vary by region, reflecting the experimental, play-oriented nature of the platform.
