## When to prefer this

Use this endpoint when you want a quick pulse on which prediction markets are dominating social conversation on X, without specifying a particular market question. Prefer this over the per-question sentiment endpoint when you don't already have a specific market in mind and want to discover trending opportunities organically.

## Known failure modes

- No markets returned if sentiment data is unavailable or cached data is stale
- 503 or timeout if the Render-hosted service is cold-starting (free tier spin-up delay)
- Empty or partial results if fewer than three markets have recent X sentiment data
- 402 payment required if the x402 payment header is missing or invalid
