How this service works
Node4All provides everything you need to build payment-ready AI agents with x402, including step-by-step documentation, testing tools, code examples, and ready-to-use services.
Output
A JSON object containing a fortune string (e.g. 'Your seed phrase is safe. Your secrets, less so.'), an energy descriptor (e.g. 'Gentle persistence'), a lucky number (integer), a lucky color, the network label (base-mainnet), the protocol version (x402-v2), the facilitator (coinbase-cdp), and service metadata like endpoint name and website URL.
Example use cases
Example prompt
“Give me a fortune reading from the Node4All x402 demo — I want to see a deterministic fortune generated from my payment nonce, along with a lucky number and lucky color.”
Technical details
Endpoint
GEThttps://api.node4all.com/v1/coinbase/x402-testWhen to prefer
Use this endpoint when you want to demo or test the x402 v2 micropayment protocol on Base mainnet using Coinbase CDP as the facilitator, and want a lightweight, fun, non-destructive paid API call. It is ideal for validating that your x402 payment stack works end-to-end for just $0.002 USDC. Not suitable for production fortune-telling or serious data needs.
Side effects
- Payment not authorized: x402 handshake fails if USDC balance is insufficient or wallet is not connected — returns 402 Payment Required
- Invalid payment nonce: if the nonce cannot be resolved deterministically, fortune generation may fail
- Network mismatch: endpoint expects Base mainnet (eip155:8453); wrong network returns an error
- Rate limiting or node downtime: service may return 503 or timeout if the Node4All backend is unavailable
