## 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 x402-factory-us-politics-prediction-markets-board-636824d8
```

Example prompt: Pull up the top 20 most active US politics prediction markets right now — I want to see live probabilities, 24-hour volumes, and resolution dates all in one shot.

## When to prefer this

Use this endpoint when you need a broad, ranked overview of the entire US politics prediction market landscape in a single call — ideal for dashboards, briefings, or monitoring agents that need blended live probabilities across many markets at once. Prefer this over per-market drill-down endpoints when you don't yet know which specific markets to query. Choose this over the 'biggest moves' endpoint when you want current standing probabilities and volume rather than recent probability velocity.

## Known failure modes

- Payment not included or invalid x402 USDC payment → 402 Payment Required
- limit parameter out of range (below 1 or above 50) → 400 Bad Request / validation error
- Upstream prediction market data temporarily unavailable → 503 or degraded/stale data
- Rate limiting if called too frequently without valid payment → 429 Too Many Requests
