How this service works

Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/crypto/top-coins?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a ranked market overview or sector screener across the top cryptocurrencies — especially when you want category filtering (layer-1, meme tokens, AI tokens, RWA) alongside standard market metrics like price change and volume. Prefer this over single-coin profile endpoints when comparing multiple assets or building dashboards.
Side effects
- Invalid category id returns empty results or error — must use valid CoinGecko category slug
- Limit out of range (below 1 or above 250) may return an error or be clamped
- Rate limiting or upstream CoinGecko API unavailability may cause 5xx errors
- Stale data if CoinGecko feed is delayed
