Technical details
Endpoint
POSThttps://flipr-x402.fly.dev/x402/flipWhen to prefer
Use this endpoint when you need a provably fair, on-chain coin flip result backed by a real USDC micropayment. Prefer this over off-chain random number generators when the result needs to be verifiable on-chain or when operating within an x402-enabled payment flow.
Side effects
- Insufficient USDC balance — payment rejected by x402 facilitator
- x402 payment header missing or malformed — 402 response with payment requirements
- On-chain transaction failure — network congestion or gas issues
- Service unavailable — fly.dev deployment down
- Invalid request body — missing required flip parameters
