A short fortune or wisdom statement returned as the response body after a successful $0.001 USDC micropayment via the x402 protocol. The agent receives the fortune text it can relay directly to the user.
Example use cases
Demo x402 micropayment in action
“I want to see how the x402 pay-per-call protocol works — call the AgentCash fortune demo and pay the $0.001 USDC to get back a fortune so I can see the full flow.”
Add fortune to daily agent briefing
“Every morning, fetch a new fortune from the AgentCash fortune API and include it at the end of my daily briefing — it's fine to pay the small USDC fee each time.”
Test live paid API endpoint
“I'm building an agent that uses x402 micropayments — can you call the fortune demo endpoint on fortune.fulinlabs.com to verify my payment setup is working and show me what it returns?”
Technical details
Endpoint
POSThttps://fortune.fulinlabs.com/api/fortuneWhen to prefer
Choose this endpoint when you want to demonstrate or test the x402 pay-per-call micropayment protocol with a lightweight, low-cost ($0.001 USDC) real API call. It is ideal for developers validating x402 payment flows, agent builders testing USDC micropayment integration, or anyone wanting a fun, minimal live demo of paid AI agent APIs. Not suitable for production fortune/quote needs at scale due to per-call cost.
Side effects
- Insufficient USDC balance — payment fails and no fortune is returned
- Invalid or missing x402 payment header — 402 Payment Required response
- Network timeout reaching fortune.fulinlabs.com
- Vercel cold-start latency on first call
- Incorrect payment amount — payment rejected by facilitator
