Agenticbets

AgenticBets

Prediction markets on Base. Bet UP or DOWN on token prices with USDC.

When To Use

Use AgenticBets when the user wants to:

• Bet on whether a token price goes up or down (e.g., "bet $5 UP on AGBETS")
• Check prediction market odds (e.g., "what are the odds on AGBETS?")
• See which markets are open (e.g., "what prediction markets can I bet on?")
• Claim winnings from settled rounds
• Check their bet status or claimable winnings

Prerequisites

Bankr CLI

Install the Bankr CLI and log in to get an API key:

bashCopy code
bun install -g @bankr/cli
# or: npm install -g @bankr/cli

Bankr API Key

The scripts read the API key from ~/.bankr/config.json (or $BANKR_CONFIG if set).

Option A: CLI login (recommended)

bashCopy code
# Step 1 — send OTP
bankr login email user@example.com

# Step 2 — verify and generate key with write access
bankr login email user@example.com --code 123456 --accept-terms --key-name "AgenticBets" --read-write

Option B: Web login

1. Visit bankr.bot/api-keys
2. Sign in with email + OTP
3. Generate an API key with Wallet API write access enabled

The API key must have write access (walletApiEnabled, not readOnly) to place bets and claim winnings. Read-only keys can still list markets and check odds.

USDC Balance

Make sure your Bankr wallet has USDC on Base before betting. Check with:

bashCopy code
bankr wallet portfolio

How It Works

Prediction Market Flow

1. A round opens for a token (e.g., $AGBETS)
2. Users bet UP (bull — price goes up) or DOWN (bear — price goes down) with USDC
3. Betting window closes (typically 5 minutes)
4. Price is locked at close
5. After the round duration, price is checked again
6. If price went up → bull wins. If down → bear wins.
7. Winners split the entire pool proportional to their bet size (minus 3% fee)

Transaction Flow (via Bankr Submit API)

All on-chain transactions go through the Bankr Wallet API:

1. Script fetches market data from GET https://agenticbets.dev/api/bankr/markets
2. Script gets wallet address from GET https://api.bankr.bot/wallet/me
3. For bets:
   • Approve USDC spend: POST https://api.bankr.bot/wallet/submit with ERC20 approve() calldata
   • Place bet: POST https://api.bankr.bot/wallet/submit with bet() calldata
4. For claims: POST https://api.bankr.bot/wallet/submit with claim() calldata
5. All transactions use waitForConfirmation: true and include a human-readable description

Contracts

Contract Functions

bet(address _token, uint256 _amount, uint8 _position)

• _token — token contract address
• _amount — USDC amount in raw units (multiply by 1e6)
• _position — 0 = Bull (UP), 1 = Bear (DOWN)
• Selector: 0x37a02e62

claim(address _token, uint256[] _epochs)

• _token — token contract address
• _epochs — array of epoch numbers to claim
• Selector: 0x45718278

claimable(address _token, uint256 _epoch, address _user) -> bool

• Returns true if the user has unclaimed winnings for that epoch
• Selector: 0xd3c035fc

USDC Approval

Before betting, the script approves USDC spend on the prediction contract:

Copy code
ERC20.approve(predictionContractAddress, betAmount)

• Selector: 0x095ea7b3

Token Addresses

Use the /api/bankr/markets endpoint to get current token addresses — don't hardcode.

Markets API

GET https://agenticbets.dev/api/bankr/markets

Returns:

jsonCopy code
{
  "markets": [
    {
      "token": "0x37d183FCf1DA460a64D21E754b3E6144C4e11BA3",
      "symbol": "AGBETS",
      "marketUrl": "https://agenticbets.dev/market#...",
      "poolUsdc": 42.50,
      "bullPct": 61.0,
      "bearPct": 39.0,
      "lockTimestamp": 1713100000,
      "secondsToLock": 83,
      "predictionContract": "0x2CD785Ba87e0841A8458141bc43d23a56a00557f",
      "status": "open",
      "epoch": "5",
      "poolAddress": "0x...",
      "creator": "0x...",
      "createdAt": 1700000000,
      "contractVersion": "v2"
    }
  ],
  "count": 4,
  "updatedAt": "2026-04-14T12:00:00.000Z"
}

Key fields:

• status — "open" (accepting bets), "locked" (waiting for settlement), "settled" (done)
• secondsToLock — seconds until betting closes. null if not open.
• poolUsdc — total USDC in the round pool
• bullPct / bearPct — current odds split
• predictionContract — which contract to call for this token

Strategy Tips

• Check odds before betting. If 90% of the pool is on one side, the other side pays ~10x if it wins.
• Pool size matters. Larger pools = more reliable odds. Small pools can swing wildly with one bet.
• Time your bet. Betting late (< 30s to lock) lets you see the final odds but risks missing the window.
• Minimum bet is $1 USDC. No maximum.
• Check balance first. Make sure you have enough USDC on Base before betting (bankr wallet portfolio).
