How this service works
Pay-per-call fortune API on x402 and MPP, deployed in one click to Vercel.
Output
A short fortune or prediction text returned after the $0.005 USDC micropayment is processed via x402. The response is a premium fortune message, distinct from any free tier, delivered as a JSON payload or plain text string.
Example use cases
Demo x402 micropayment flow
“I want to test the x402 pay-per-call protocol end to end — call the premium fortune endpoint and pay the $0.005 USDC fee automatically so I can see a real micropayment transaction go through.”
Agent daily fortune ritual
“Every morning, fetch me a premium fortune from the AgentCash fortune API and pay the micro-fee in USDC — just give me today's fortune as part of my daily briefing.”
Developer testing paid API integration
“I'm building an agent that uses machine-payable APIs — can you call the premium fortune endpoint right now to verify that my x402 payment middleware is working correctly?”
Technical details
Endpoint
POSThttps://fortune.fulinlabs.com/api/fortune/premiumWhen to prefer
Choose this endpoint when you want to demonstrate or test the x402 machine-payable API protocol with a real USDC micropayment, or when you need a lightweight, deployable example of a pay-per-call AI agent API. It is ideal for developers exploring agent-native payment flows, not for production fortune or prediction use cases at scale.
Side effects
- Payment rejected — insufficient USDC balance or malformed x402 payment header returns a 402 Payment Required error
- Invalid or missing payment header results in access denial
- Network timeout on Vercel cold start may cause delayed or failed response
- Incorrect USDC amount tendered returns payment validation failure
