## 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-markets-endpoint-get-market-by-id-18a182eb
```

Example prompt: Can you pull up the market data for ID 'mkt_42' on lilambd and tell me what's in it?

## When to prefer this

Use this endpoint when you need to retrieve structured market data for a known market ID from the lilambd platform, especially when the attribution/license metadata matters. Prefer this over generic data APIs when operating within the lilambd ecosystem of play, language, and computation-oriented markets.

## Known failure modes

- Invalid or unknown market ID returns empty data array with count 0
- Missing required path parameter `id` results in a routing error
- Network or payment failure (x402 micropayment not processed) prevents access
- Rate limiting or quota exceeded may return an error response
- Malformed query parameters may yield unexpected empty results

## How this service works

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

## Output

A JSON object containing a `data` array with market records, a `count` integer indicating the number of results, and an `attribution` string describing the source license for the data.
