```sh
zero fetch --capability lilambd-crossing-land-classes-32c0ac0c
```

Example prompt: Can you fetch the list of land classes available on lilambd crossing so I can see what categories of play, feeling, and computation are on offer?

## When to prefer this

Use this endpoint when you need to discover or list the available 'land' classes on the lilambd crossing platform, particularly when building workflows that intersect play, language, feeling, science, and computation in novel or experimental ways. It is best suited for exploration and discovery of what the lilambd system offers before invoking more specific endpoints.

## Known failure modes

- 402 Payment Required if the $0.005 USDC payment is not provided via x402 protocol
- Empty or minimal response if no classes are currently defined
- Malformed JSON if the endpoint is in an early or experimental state
- Network timeout if the service is unavailable
- Unexpected schema shape due to the highly experimental nature of the platform
