Technical details
Endpoint
GEThttps://x402-crypto-apis.onrender.com/api/crypto/topWhen to prefer
Choose this endpoint when you need a quick, ranked snapshot of the top cryptocurrency market — prices, market cap, and 24h change — without needing deep historical data or order book information. It is ideal for market overviews, dashboards, or agent workflows that need current macro crypto context. Prefer it over exchange-specific APIs when broad market ranking (CoinGecko-sourced) matters more than trading depth.
Side effects
- Payment not included or rejected (402) — x402 payment header missing or insufficient USDC
- Invalid limit parameter (400) — non-integer or out-of-range value
- CoinGecko upstream unavailable (503) — data provider outage causing empty or stale response
- Rate limit exceeded — too many calls in a short window
- Network timeout on render.com cold start — first request may be slow if service is sleeping
