## 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`):

## When to prefer this

Use this endpoint when an AI agent needs to discover or surface active prediction markets relevant to a specific event, topic, or keyword — particularly when integrating with workflows that require browsing available market options before placing or analyzing bets. Prefer this over general finance APIs when the goal is specifically prediction market discovery rather than price data or historical market analytics.

## Known failure modes

- Missing required 'q' query parameter returns an error
- No markets found for the given query returns an empty list
- limit out of range (outside 1-10) may return an error or default behavior
- Payment not completed (x402) results in 402 Payment Required response
- Upstream prediction market data unavailable returns a service error
