Endpoint
POSThttps://x402-crypto.vercel.app/api/coinbase-realtime/%7Bpath%7DWhen to prefer
Choose this endpoint when you need real-time cryptocurrency price or market data sourced directly from Coinbase, particularly in agentic workflows that support x402 micropayment protocols. It is ideal for trading bots, portfolio trackers, or price alert systems that require fresh, per-call data without long-term subscription overhead. Prefer this over REST-only alternatives when your stack supports automatic x402 payment handling.
Side effects
- Invalid or unsupported trading pair symbol returns an error or empty data payload
- Payment failure or insufficient USDC balance causes a 402 Payment Required response and no data is returned
- Network or upstream Coinbase API unavailability results in a timeout or 5xx error
- Malformed query string (missing or incorrectly formatted symbol) causes a validation error
- Rate limiting or x402 facilitator issues may block repeated rapid requests
