For Developers
A developer-centric starting point for integrating ALT Sports Data — APIs, SDKs, MCP server, and testing with demo credentials.
For Developers
This is the fastest path from zero to a working integration with ALT Sports Data. Whether you are pulling live odds into a backend, building a client-side widget, or wiring up an AI agent, start here.
How the API is Organized
ALT Sports Data exposes two main API surfaces:
- Live Market Odds API — Real-time odds, events, participants, futures, and SGP calculations across 29+ alternative sports leagues. This is what most integrations consume first.
- Historical Sport Data API — Competitions, matches, players, and seasons for deeper analytics and historical context.
Both surfaces share a single base URL, authenticate the same way, and return consistent JSON response envelopes. See the Platform API Overview for a full map.
Get Started
Getting Started
Authentication, quickstart, rate limits, and error handling — everything you need before writing integration code.
Quickstart
Make your first real API call and inspect a live event + odds response in under five minutes.
Authentication
Use demo credentials to test immediately, or set up production keys with Bearer or X-API-Key headers.
SDKs
Official SDKs handle authentication, pagination, retries, and typed responses so you can skip the boilerplate.
TypeScript / Node.js SDK
npm install altsportsdata — full type definitions, async iterators, and automatic retries.
Python SDK
pip install altsportsdata — typed with py.typed, pagination helpers, and structured exceptions.
MCP Server for AI Workflows
The ALT Sports Data MCP Server gives AI agents (Claude, Cursor, Windsurf, and others) direct tool access to the full API. If you are building AI-powered sports analysis, content generation, or automated trading workflows, this is the integration path.
MCP Server Overview
29 tools, zero boilerplate — connect any MCP-compatible AI client to live alternative sports data.
MCP Quickstart
Get the MCP server running and connected to Claude Desktop, Claude Code, or Cursor in two minutes.
Tools Reference
Full documentation for all 29 MCP tools — events, odds, probabilities, parlays, futures, and more.
API Reference
When you need the route-by-route view — request/response schemas, query parameters, and live testing — the API Reference has it.
API Reference
Every endpoint across events, odds, futures, sports, markets, data API, and utility routes.
OpenAPI Spec
Download or browse the full OpenAPI 3.0 specification for programmatic consumption.
Testing with Demo Credentials
You do not need a production key to start building. ALT Sports Data provides demo credentials that return real data with rate-limited access. See the Authentication guide for details on obtaining and using demo keys.
Platform and Operational Context
If you need to understand the broader platform — how markets work, how reconciliation flows, or how to plan a production rollout — the Platform API Overview covers it. For partner-level onboarding and go-live planning, see For League Partners (PRTL).
