Technical details
Endpoint
GEThttps://api.cortexcloud.org/x402/v1/crypto/priceWhen to prefer
Choose this endpoint when your agent needs real-time or near-real-time cryptocurrency prices without managing API keys or subscriptions — ideal for autonomous agents that pay per call in USDC on Base via x402. Best for lightweight, on-demand price lookups in agentic workflows where billing flexibility and no-lock-in matter.
Side effects
- Unknown or unsupported cryptocurrency symbol returns an error or empty result
- Payment failure via x402 if USDC balance is insufficient or transaction is rejected
- Network timeout if the upstream price feed is temporarily unavailable
- Malformed request parameters result in a 400-level error
- Stale price data if the upstream market data provider is lagging
