0xinsider Developer API and MCP
0xinsider is Polymarket analytics for sports and esports in real-time. The Developer API returns the same Polymarket sports and esports data, typed, for agents, bots, dashboards, and research tools. Start with API discovery. Then pick an operation and its schema from the OpenAPI specification. Data endpoints take an API key in an Authorization: Bearer header. Discovery and health endpoints are public.
When to use this
Use the API for current large trades, tracked-wallet analytics, market search, sharp-money flow, reports, or durable event replay. Use the npm package for a local stdio MCP client. Call the Streamable HTTP MCP endpoint when the client can send an Authorization header.
