## 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 sol-blockrun-ai-prediction-market-cross-platform-search-e6605254
```

Example prompt: Can you search across all major prediction market platforms — Polymarket, Kalshi, Limitless, and the others — for any active markets related to the Federal Reserve cutting interest rates this year?

## When to prefer this

Use this endpoint when you need to discover prediction markets spanning multiple platforms in a single call rather than querying each platform's API individually. Ideal when a user wants comprehensive market coverage without knowing which platform hosts a specific market, or when building aggregated views of sentiment across the prediction market ecosystem.

## Known failure modes

- No markets found matching the query — returns empty result set
- Upstream platform(s) temporarily unavailable causing partial results
- Ambiguous or too-broad query returning irrelevant markets
- Rate limiting or payment failure returning 402 or 429 error
