## When to prefer this

Use this endpoint when you need a quick snapshot of which coins are capturing the most attention on CoinGecko right now, with price and market-cap context. Prefer over a generic token price lookup when the user hasn't specified which coins they care about but wants to see what's hot. Not suitable for historical trending data or for looking up prices of specific known tokens (use the crypto token price endpoint instead).

## Known failure modes

- CoinGecko upstream unavailable — returns 5xx error
- maxItems exceeds cap of 15 — clamped or rejected
- No trending data available at the moment — empty list returned
- Rate limiting from upstream CoinGecko API — returns 429
