Example prompt: What are the trending prediction markets right now across Polymarket and Kalshi? Show me what events people are currently betting on.

## When to prefer this

Choose this endpoint when you need a single aggregated feed of trending prediction markets from both Polymarket and Kalshi simultaneously, rather than querying each platform separately. It is ideal for agents that need a quick, unified snapshot of what markets are currently popular without managing multiple API integrations.

## Known failure modes

- Upstream Polymarket or Kalshi APIs unavailable — returns partial or empty events array
- Rate limiting or payment failure — 402 response requiring valid x402 payment
- Stale data if aggregation pipeline is delayed — check generated_at timestamp
- Empty events array if no trending markets are currently available
