## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability even-steven-bet-quote-5f86f90c -d '<json body>'
```

Example prompt: Give me an Even Steven quote for game ID 'nfl-2024-kc-buf' — I want to bet 50 USDC on the home side and see the current line I'd lock, the gross payout at liquidity, and the total cost including the 2% fee.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
