Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh

```

## When to prefer this

Use this endpoint when an agent needs to quickly look up crowd-sourced prediction market probabilities for a specific event, topic, or decision. Best suited for finance, politics, sports, or crypto event queries where implied probability from prediction markets is more useful than traditional odds or news sentiment alone.

## Known failure modes

- Missing required 'q' parameter returns an error
- No markets found for obscure or misspelled event query
- Limit parameter outside 1-10 range may be rejected or clamped
- Network or upstream data provider outage may return empty or error response
- Ambiguous query terms may return loosely matched markets
