Technical details
Endpoint
GEThttps://likelihoods.io/api/tools/polymarket/trendingWhen to prefer
Use this endpoint when you need a real-time snapshot of the most actively traded or highly liquid Polymarket prediction markets, without needing to specify a category or search term. Prefer this over market search endpoints when the user wants a broad overview of what's trending rather than a specific market or topic.
Side effects
- Polymarket Gamma API unavailable — upstream service outage causing empty or error response
- Stale data if Polymarket's trending algorithm hasn't updated recently
- Payment failure (x402) if USDC balance is insufficient for the $0.01 per-call fee
- Rate limiting or authentication errors from the facilitator layer
