How this service works
Quote one Even Steven bet: the even-money payout at liquidity, the early line you would lock right now, and the flat 2% fee on stake paid upfront.
Output
Returns a JSON object with: the locked line (currentZ and display), gross payout at liquidity (2x stake), gross payout at current pools, net profit after total cost, the fee amount in USDC (2% of stake), total cost to authorize (stake + fee), the side and gameId echoed back, and the on-chain market address on Base.
Example use cases
Pre-bet payout preview
“Before I commit anything, quote me the Even Steven odds on game 'nba-2024-gsw-lal' — I'm thinking 100 USDC on the away side. Show me what I'd gross at liquidity, the line I'd lock now, and exactly how much I'd owe with the fee.”
Fee calculation for bankroll planning
“I want to know the total cost including the 2% upfront fee if I stake 250 USDC on the home team for game 'mlb-2024-nyy-bos' on Even Steven — what's my break-even and net profit at full liquidity?”
Line shopping before market moves
“What's the current line I can lock right now on Even Steven for game 'nfl-2024-sf-phi' if I bet 75 USDC on the away team? I want to see the currentZ before it shifts.”
Technical details
Endpoint
POSThttps://evensteven.bet/api/bet/quote?utm_source=zero.xyzWhen to prefer
Use this endpoint when a user wants to preview the exact cost and payout of an even-money sports bet on Even Steven before committing funds. It is a read-only quote with no side effects, making it ideal for comparison, bankroll planning, or line-checking workflows. Prefer this over placing a bet directly when user confirmation or fee transparency is needed first.
Side effects
- Invalid or unknown gameId returns an error or empty market
- Stake below minimum threshold may be rejected
- Malformed side value (not 'home' or 'away') causes validation error
- Insufficient liquidity in the pool may produce degraded currentPayout
- x402 payment failure if USDC balance or authorization is insufficient
- Network or Base RPC issues may cause timeout
