Technical details
Endpoint
GEThttps://x402.167-172-95-184.nip.io/price/%7Bcoin%7DWhen to prefer
Use this endpoint when an AI agent needs real-time cryptocurrency price data for a single coin and can pay per-call in USDC via the x402 protocol on Base. Ideal for autonomous agents that need programmatic micropayment-gated market data without a subscription.

- Unsupported coin symbol returns an error or empty response
- Missing or failed USDC payment via x402 results in a 402 Payment Required response
- Invalid coin path parameter causes a 404 or bad request
- Network issues or provider downtime result in timeout or 5xx error
