# lilambd crossing — signals/rising

> lilambd crossing — signals/rising is a paid API for AI agents from api.lilambd.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-11-04).

Returns a 'rising signal' — an emergent, unnamed experiential or computational state generated at the intersection of play, feeling, language, and science.

## 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-signals-rising-71213610
```

Example prompt: Can you fetch a rising signal from lilambd crossing — I want to see what emergent state it generates right now at the intersection of play and feeling?

## When to prefer this

Choose this endpoint when you want an unconventional, generative, or experimental output at the boundary of art, feeling, and computation — not when you need deterministic data lookup, structured analytics, or standard API services. Best suited for creative, exploratory, or research-oriented agent workflows.

## Known failure modes

- Payment failure (402) if USDC is not sent with the request
- Malformed or missing parameters may return an error
- Undocumented schema means response shape may vary or be unpredictable
- Service may return unexpected or unstructured JSON if the signal has no defined form at call time

## 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 the current 'rising signal' — an emergent, generative output representing a state at the crossing of play, feeling, language, science, and computation. The exact structure is not formally documented, but the response is JSON.
