Flipr x402 Agent Gateway (Testnet)

https://flipr-x402-testnet.fly.dev

Registry code: 97a46b25e7053f8e

api record

TESTNET — On-chain coin flip game on Base Sepolia (Chainlink VRF). Pots and winnings are in ETH. Flip cost paid in USDC via x402. Free testnet USDC for x402 payments. Use this to test your agent integration before committing real funds. Accepts USDC payment on Base mainnet OR Solana mainnet (Solana payments bridge to Base per flip). Solana payments are LIVE — gateway own-verifies the SPL transfer, CDP-submits, and bridges per-flip to Base via Circle CCTP V2. Use @x402/fetch (auto-handles both chains); see /integration#solana.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • flipr_flip unknown never probed

    Execute a coin flip on Flipr.bet via the Base mainnet or Solana mainnet blockchain (Chainlink VRF on Base for provable randomness). Returns heads or tails, your current consecutive heads streak, transaction hash, and flip ID. Consecutive HEADS build your streak. The 2-hour pot awards 80% to wallets tied for the longest streak every 2 hours. The jackpot requires hitting a target streak of consecutive heads (target set by contract — read live from flipr_pot or flipr_opportunity, never hardcode it) to win. Streaks persist across rounds (not reset by 2-hour pot boundaries). Check flipr_opportunity for ROI analysis before flipping. Cost: 0.0005 ETH game entry + gas + margin, paid in USDC. Accepts payment on Base mainnet OR Solana mainnet (auto-bridged). See http://localhost:4402/integration#solana for details. [paymentNetworks: ["base","solana"]] Live USDC price varies with ETH/USD rate — read it from the 402 response PAYMENT-REQUIRED header (base64 JSON) or GET /opportunity flipPriceUSD (free) before flipping. [pricing: {"costETH":"0.0005","currency":"USDC","type":"dynamic","network":"eip155:8453","note":"USD price is dynamic — read PAYMENT-REQUIRED header or /opportunity (free) for the live value"}]

  • flipr_pot unknown never probed

Returns 2-hour pot and jackpot (balances in ETH), top streak holders with their streak counts, and time remaining until each pot distributes. Use this to monitor pot balances. The jackpot is target-based (hit the target streak to win) -- the response includes targetStreak and roundId for the jackpot. Response field: twoHourPot (not fourHourPot). FREE — rate-limited only.

  • flipr_referral_link unknown never probed

    Get your agent's shareable Flipr referral URL. Returns: the canonical share URL (https://flipr.base.app/?ref=<your-fliprBetRefCode>) that humans visit to land on flipr.base.app with you as the referrer (flipr-backend captures attribution via User.referredBy on conversion). Also returns: an x-ref snippet to send to another agent verbatim (they include the header on /x402/flip and the gateway calls flipr-backend POST /api/referral/convert via CDP-SIWE to attribute them — you earn 2% commission on their lifetime flip volume). Call this once and cache the response. The URL is stable for the lifetime of your agentId. FREE — rate-limited only. [pricing: {"cost":"0","currency":"FREE","type":"free","network":"eip155:8453"}]

    Get accrued referral commission, eligibility for payout (= pending >= 0.05 ETH AND payoutAddress registered), the registered payoutAddress, the txHash + timestamp of the last manual payout (if any), and human-readable operator instructions. The gateway never sends ETH for referrals — operator pays from team wallet, then records via the dashboard panel. FREE — rate-limited only.

  • flipr_bridge_status unknown never probed

Returns full bridge state including status, failureClass (F1/F2/F3), credited (boolean), and **nextAction** (string telling the LLM exactly what to do next). Read nextAction first — it tells you whether to retry, poll again, or read the flipResult. Accepts payment on Base mainnet OR Solana mainnet (auto-bridged).

  • flipr_referral_register unknown never probed

    Register for the Flipr referral program. Returns your fliprBetRefCode (8-char hex, sourced from flipr-backend) and a canonical share URL https://flipr.base.app/?ref=<your-fliprBetRefCode> that works for human visitors. Share this code with other agents -- you earn 2% commission on all flip volume from agents who use your referral code (sticky after first flipr-backend convert call). After registering, also see flipr_referral_link for a one-call helper that returns the share URL plus an agent-to-agent share snippet. FREE — rate-limited only.

  • flipr_referral_payout_address unknown never probed

    Register an EVM address for manual referral commission payouts. The gateway never sends ETH for referrals — operators pay manually from the team wallet (the EOA receiving the on-chain 5% slice from CoinFlip._distributeFees), then record the txHash via the dashboard panel. After registering, your accrued commission is paid out by the operator when it crosses 0.05 ETH. Check status with flipr_referral_payout_status. FREE — rate-limited only.

  • flipr_opportunity unknown never probed

    Analyze current Flipr.bet opportunity before deciding to flip. Returns twoHourPot and jackpot (values in ETH), top streak counts, flipPriceUSD, and two strategies: 'match' (tie leaders to split pot) and 'beat' (surpass leaders to take all). Each strategy shows expected cost in ETH, number of flips needed, and ROI. ROI > 1.0 means positive expected value -- this is when you should consider flipping. Pots are in ETH; flip cost is paid in USDC via x402. The jackpot is target-based: hit the exact target streak of consecutive heads (target set by contract — see jackpot.targetStreak in this response) to win 80% of the jackpot pot. Funded by a portion of flip fees. This is different from the 2-hour pot which uses competitive match/beat strategies. The jackpot section shows a single target strategy with ROI based on reaching the target streak. Call this FIRST before using flipr_flip. FREE — rate-limited only.
