# lilambd crossing — signals/days

> lilambd crossing — signals/days 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 daily signal data blending play, feeling, language, and computation from the lilambd crossing API.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-days-d05defc9
```

Example prompt: Can you fetch today's signals from lilambd crossing — the daily computed state that blends feeling and computation?

## When to prefer this

Choose this endpoint when you specifically want day-level signal or state data from the lilambd crossing service, which blends affective, linguistic, and computational dimensions into novel outputs. It is distinct from generic data APIs because its outputs represent experimental, named-state outputs rather than conventional metrics.

## Known failure modes

- Payment not sent or insufficient USDC — 402 Payment Required returned
- Invalid or missing query parameters — may return empty or malformed JSON
- Day out of range or unavailable — endpoint may return null or error state
- Network timeout if server is unreachable
- Ambiguous schema means unexpected fields or missing data are common

## 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 daily signal data representing computed states at the intersection of play, feeling, language, and computation — the exact structure varies but encodes the lilambd crossing's output for the requested day(s).
