## 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-exchanges-by-mic-54076fa9
```

Example prompt: Can you pull the exchange data for MIC code XNAS from lilambd crossing and tell me what it returns, including the attribution line?

## When to prefer this

Choose this endpoint when you need to look up exchange or market data keyed by a standard MIC (Market Identifier Code) and want structured JSON output with source attribution. It is particularly useful for agents operating in financial, scientific, or interdisciplinary data pipelines that need lightweight per-call lookups at low cost.

## Known failure modes

- Invalid or unknown MIC code returns empty data array with count 0
- Missing required 'mic' path parameter results in a routing error or 402 payment required
- Network or server error returns non-200 status
- Payment not processed (x402) results in 402 response before data is returned

## 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 containing a 'data' array of exchange records, a 'count' integer indicating number of results, and an 'attribution' string with the source licence line.
