```

## When to prefer this

Choose this endpoint when you need to surface prediction markets that are receiving sudden public attention, combining Wikipedia trend signals with Polymarket pricing and skilled-trader scoring in a single call. It is superior to browsing Polymarket directly when you want attention-filtered discovery rather than browsing by volume or category.

## Known failure modes

- No matching markets found if no trending Wikipedia topics currently overlap with open Polymarket markets
- limit parameter out of range (must be 1–10) causes validation error
- Invalid lang code returns empty or error response
- Rate limiting or payment failure if USDC balance is insufficient

## How this service works

Attention meets prediction markets: topics trending or spiking on Wikipedia matched to open Polymarket markets, each with prices and the skilled-trader lean from x402Pulse scoring. Find markets the public is suddenly paying attention to. Data, not investment advice.

## Output

A list of prediction markets (up to 10) where each entry includes a trending Wikipedia topic, the matched Polymarket market details, current YES/NO prices, and an x402Pulse skilled-trader lean score indicating which direction informed traders favor.
