## 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-crossing-rules-ahead-upcoming-251139f2
```

Example prompt: Can you fetch what's coming up next on the lilambd crossing — I want to see the upcoming rules or events scheduled there?

## When to prefer this

Use this endpoint when you specifically need to query the lilambd platform's upcoming rules or schedule feed. This is a niche experimental creative-computational service; prefer it only when the user is explicitly interested in lilambd's experimental intersection of play, language, feeling, and computation — not for general scheduling, event listing, or creative generation APIs.

## Known failure modes

- Payment required (402) if USDC payment header is missing or insufficient
- Empty or minimal response if no upcoming rules are currently scheduled
- Malformed or opaque JSON if the platform's internal state is in flux
- Timeout if the experimental platform is temporarily unavailable
- Undocumented schema changes since the platform appears highly experimental

## How this service works

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

## Output

A JSON response containing upcoming rules, events, or scheduled states from the lilambd creative-computational crossing platform. The structure is loosely defined and may include named or nameless computational/creative states, timing information, or rule definitions.
