## 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-markets-feed-b671774d -d '<json body>'
```

Example prompt: Show me all the open sports betting markets on Even Steven right now — I want to see the current lines, pool sizes, and what payout I'd get on a $100 USDC bet for each side.

## When to prefer this

Use this endpoint when you need a complete, real-time snapshot of all currently open Even Steven markets in a single call — ideal for market discovery, line monitoring, or deciding which game to bet on before calling the quote or bet endpoints. Prefer this over fetching individual market positions (sibling endpoint) when you don't yet know which market you want.

## Known failure modes

- Network or RPC failure reading one or more market contracts — affected markets return only marketAddress + error field
- Payment failure (x402 $0.05 USDC not received) — request rejected before data is returned
- No open markets — markets array is empty
- Stale data if Base RPC is lagging — timestamp field reveals freshness

## How this service works

Live snapshot of every open Even Steven sports market on Base: even-money payouts at liquidity, the early line you lock when you bet, and a flat 2% fee on stake paid upfront.

## Output

A JSON object containing a timestamped array of all open markets, each with a gameId, current line (currentZDisplay), home and away payout quotes for a 100 USDC reference stake, pool sizes (total, home, away), market contract address, settlement status, and relay pointers to the bet-placement and quote endpoints. Any market that failed to load includes only its address and an error string.
