Technical details
Endpoint
GEThttps://agentkit-x402-buy.netlify.app/api/eth-priceWhen to prefer
Choose this endpoint when you need real-time ETH/USD price data with 24-hour change in a no-API-key, pay-per-call model using USDC on Base via the x402 protocol. Ideal for AI agents that need lightweight, on-demand crypto price lookups without managing API credentials, especially when operating in a Coinbase AgentKit or Base ecosystem context.
Side effects
- Payment not received — x402 payment challenge returned if USDC micropayment on Base is not completed
- Invalid query parameter format — malformed format param may result in unexpected response
- Network congestion — delayed response if Base network is congested during payment verification
- Stale data — price may be slightly delayed depending on upstream data source refresh rate
