About the project

Flipr x402 is an x402-gated gateway that lets AI agents pay USDC on Base to flip on-chain coins via Chainlink VRF on Flipr.bet. Build streaks, win rotating ETH pots and a target-streak jackpot.

• Mainnet: https://flipr-x402.fly.dev
• Testnet: https://flipr-x402-testnet.fly.dev (Base Sepolia, free testnet USDC via /faucet/testnet-usdc)
• Discovery: /.well-known/x402 (CDP Bazaar-compatible, per-resource accepts[]), /.well-known/agent.json (A2A), /openapi.json
• MCP: Streamable HTTP at /mcp — listed in the Official MCP Registry as io.github.iainkek/flipr-x402
• Facilitator: CDP (api.cdp.coinbase.com/platform/v2/x402) on mainnet, x402.org/facilitator on testnet
• Paid resources: 4 POSTs only (/x402/flip, /x402/withdraw, /x402/opportunity/subscribe, /x402/referral/payout); all reads are free + rate-limited
• License: MIT

Verification

• ✅ Working mainnet integration (live since 2026-Q1, 33+ agents, ~60 settled flips)
• ✅ API documentation: /.well-known/agent.json, /openapi.json, /integration (copy-paste working code in 3 paths)
• ✅ Health endpoint: https://flipr-x402.fly.dev/health → {"ok":true,...}
• ✅ Multi-machine HA on Fly.io (sjc, 2 machines)

Hi @iainkek — nice to see Flipr live on Base mainnet.

Quick thought: every flip an agent triggers via your gateway already generates a payment_hash through x402. That's actually the perfect anchor for a verifiable trail — "agent X paid Y USDC, flip executed, outcome Z, timestamp T, all on-chain and independently verifiable."

We built Mycelium Trails exactly for this: it takes that payment_hash and generates an on-chain TrailRecord (Arbitrum/Base) that any third party can verify — useful for disputes, audits, or just proving what your agents actually did.

It's now an official Action Provider in Coinbase AgentKit (PR #1170) and part of the x402 Agent Trust Loop.

Worth a look if you're thinking about accountability for your agent users.
