Example use cases

Endpoint
GEThttps://market-data-x402-5wh8-ivory.vercel.app/api/crypto/topWhen to prefer
Use this endpoint when you need a quick, ranked overview of the cryptocurrency market including gainers, losers, and market cap leaders in a single call. Prefer it over individual coin lookup endpoints when you need a market-wide leaderboard rather than data on a specific asset.
Side effects
- limit parameter missing or out of range (1-50) may cause validation error
- service unavailability on the Vercel deployment could return 5xx errors
- stale or delayed market data if upstream data provider has latency
- payment of $0.006 USDC required per call; unpaid requests return 402
