## When to prefer this

Use this endpoint when you need a real-time, crowd-sourced signal of which cryptocurrencies are capturing retail attention and search interest on CoinGecko, particularly for detecting narrative shifts or emerging hype before price movements. Prefer this over price-based endpoints when you want a leading indicator of retail interest rather than lagging price data.

## Known failure modes

- CoinGecko upstream API unavailable — may return 502 or empty result
- Rate limiting or payment failure (x402) — returns 402 Payment Required
- Network timeout if CoinGecko data source is slow to respond
- Stale data if CoinGecko feed has not refreshed recently
