Technical details
Endpoint
GEThttps://206-81-14-131.sslip.io/svc/crypto-prices/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost spot price for a cryptocurrency without setting up API keys or accounts. Ideal for AI agents that already support x402 micropayments on Base and need on-demand crypto pricing for calculations, portfolio tracking, or trade signal evaluation. Best for single-asset, real-time lookups rather than bulk historical data.
Side effects
- Unsupported or unrecognized ticker symbol returns an error or empty result
- Network issues with the sslip.io host may cause timeouts
- x402 payment failure if insufficient USDC balance on Base
- Rate limiting or transient server errors may return 5xx responses
- Price data may be delayed or stale if upstream market data provider is unavailable
