> Advanced tools for sports and esports markets on Polymarket: both sides of every game, wallet grades on settled P&L, and daily picks on a public record.

Market briefing: GET /api/v1/market/{condition_id}/context.md. Games include soccer 1X2 and EuroLeague (sport=Basketball&league=euroleague): GET /api/v1/games; list_games/get_game MCP tools. Max: get_edge_hunter (GET /api/v1/edge-hunter: board/signals/observations; kind/sport/league/type/market/event/series selectors, discovery, pagination, conditional reads). In-play source age stays within 30s across cache reuse. Board quotes use verified caches; misses are null.

## What 0xinsider does

0xinsider builds Polymarket analytics & infrastructure for sports and esports markets. The tools read public Polymarket activity on sports and esports markets: live boards with both sides of every game, wallet grades on settled P&L, large trades, positions, daily picks on a public record, market context, reports, and suspicious-trade flags.
Every feed trade gets a normalized 0.0-1.0 significance score. It ranks attention, not outcomes, and is separate from a flag's 0-100 suspicion score.
Market flow is outcome-aware: BUY YES and SELL NO add exposure; BUY NO and SELL YES subtract it. A zero-flow YES tie-break does not mean the money leans YES.
Position timelines expose outcome-specific running fill totals across pages, not complete holdings: split, merge, redemption and neg-risk activity are excluded.
Positions and holders: /llms-full.txt.

## When to use 0xinsider

Use 0xinsider for current Polymarket sports or esports market context, bounded candle history, wallet grades, side holdings, published research, or read-only alerts and dashboards.
Use REST for typed server calls, remote MCP for MCP clients, and WebMCP only with an open browser tab. Unavailable, partial, or stale provider fields are neither zeros nor predictions.

Wallet dollar volume uses verified Polymarket full-history both-sides cash volume. Missing coverage stays unavailable; leaderboard shares are never dollars.
