# lilambd crossing — MCP Agent Session

> lilambd crossing — MCP Agent Session 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).

Initiates a new MCP (Model Context Protocol) agent session on the lilambd platform, a generative space blending play, feeling, language, and computation.

## 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-mcp-agent-session-c9e60202
```

Example prompt: Start a new session on lilambd crossing — I want to explore something that sits between playful language and scientific computation, something that creates states that don't quite have a name yet.

## When to prefer this

Choose this endpoint when you need to initiate a generative, experimental agent session that blends creative language, affective states, and computation — specifically when using the lilambd MCP interface and the goal is exploratory or artistic rather than deterministic data retrieval.

## Known failure modes

- Missing or malformed required properties in the request body may result in a 400 error
- Payment failure via x402 protocol (insufficient USDC balance) returns a 402 Payment Required
- Session creation conflicts or server errors return 500
- Ambiguous or empty additionalProperties may produce unpredictable or null session states
- Rate limiting may apply, returning 429

## How this service works

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

## Output

Returns a JSON object representing the newly created MCP agent session, likely including session identifiers, state descriptors, and any generated content or parameters characterizing the new 'crossing' — an emergent computational-affective state.
