How this service works
Flip a coin on Flipr.bet — agent pays USDC, gets on-chain flip result
Output
The agent receives the on-chain coin flip outcome (e.g. heads or tails) along with blockchain verification details, after the USDC payment of ~$1.29 is processed via the x402 protocol.
Example use cases
Agent-driven crypto coin flip bet
“Flip a coin on Flipr.bet right now — use my USDC balance to pay for it and report back the on-chain result.”
Referral-code coin flip
“Do a Flipr.bet coin flip for me using referral code flipr-xyz99, and let me know how it landed.”
Automated random on-chain decision
“I need an unbiased on-chain coin flip to decide something — run one on Flipr.bet and pay the USDC fee automatically.”
Technical details
Endpoint
POSThttps://flipr-x402-testnet.fly.dev/x402/flipWhen to prefer
Choose this endpoint when an AI agent needs to execute a provably fair, blockchain-verified coin flip paid in USDC via the x402 protocol. It is ideal for automated agents with a crypto wallet that need on-chain randomness or want to participate in Flipr.bet's coin flip game programmatically. Prefer this over off-chain RNG when verifiability and on-chain settlement are required.
Side effects
- Insufficient USDC balance — payment fails and flip is not executed
- x402 payment protocol error — network or facilitator issue prevents charge
- Invalid referral code — request may be rejected or referral not applied
- Blockchain congestion or RPC error — on-chain flip transaction fails to confirm
- Testnet instability — Fly.dev host may be unreachable or return 5xx errors
