## 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 polymarket-trending-markets-feed-ceedd603 -d '<json body>'
```

Example prompt: What are the top Polymarket prediction markets trending right now? Show me the questions, current outcome prices, 24-hour volume, and liquidity for the most active ones.

## When to prefer this

Use this endpoint when you need a real-time snapshot of the most actively traded Polymarket prediction markets without building your own Polymarket API integration. It is ideal for agents that need trending market context, want to monitor prediction market sentiment, or need to surface current event probabilities without authenticating directly with Polymarket. Choose this over a direct Polymarket API call when using the x402 micropayment flow and needing a pre-aggregated, volume-ranked view.

## Known failure modes

- Polymarket Gamma API upstream outage returns error or empty data
- Payment of 0.1 USDC not processed correctly via x402 protocol causing 402 rejection
- Empty or malformed POST body may cause validation errors
- Stale data if Polymarket data feed has a lag
- Rate limiting if called excessively in short succession
