# 0xinsider

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, large trades, open positions, market context, daily picks on a public record, reports, and suspicious-trade flags. Every tracked wallet with enough history gets a grade, S to F, from its settled P&L. An answer can name which side the profitable wallets took and how much they put on it. A missing, stale, partial, or unavailable field means the provider did not report that value. A gap is not evidence that the activity did not happen.

## When to use 0xinsider

Use 0xinsider for current Polymarket sports or esports market context, to check the grade of a tracked wallet, to read which side the profitable wallets hold on a game, to search published research, or to build a read-only alert, dashboard, or research tool. Use the REST API for typed access, the remote MCP endpoint for MCP clients, and the in-page WebMCP tools when a browser tab is already open.
