## When to prefer this

Use this endpoint when you need a real-time snapshot of which cryptocurrencies the market is currently watching, ranked by trending momentum from CoinGecko. Prefer this over general market cap endpoints when the goal is to surface coins with current social/trading momentum rather than established dominance.

## Known failure modes

- CoinGecko API unavailable — upstream data source outage
- Payment failure — insufficient USDC balance or x402 payment not accepted
- Empty trending list if CoinGecko returns no trending data
- Network timeout on the upstream CoinGecko call
