Odds-API.io Review 2026

Odds-API.io is a sports odds API that aggregates 265+ bookmakers across 34 sports and 12,000+ leagues. It sits in the mid-range of the market: broader than the budget APIs that cover 20-40 books, more affordable than the enterprise feeds that start at $1,000+ per month. Paid plans begin at £49/mo, and there is a free tier with no card required.

Two things stand out in a crowded field. First, the bookmaker list includes hard-to-find sources like Bet365 and SBOBET alongside the usual US operators. Second, Odds-API.io ships an official MCP (Model Context Protocol) server, which means AI coding assistants and agent frameworks can query odds data directly. If you are building AI-powered betting tools, that integration is ready out of the box. The full landscape of options is in the sports odds API directory.

The numbers on paper are strong: 265+ bookmakers, 34 sports, 100+ market types, and 12,000+ leagues. The practical question is which books and markets actually matter to your use case.

• US books: DraftKings, FanDuel, BetMGM, and others are covered.
• International books: Bet365, Betfair, William Hill, and SBOBET. Bet365 in particular is difficult to source from many providers.
• Market types: Pre-match and live odds across moneylines, spreads, totals, and 100+ additional market types. The site does not publish a breakdown of which market types apply to which sports, so verify your specific needs against the API.

Historical odds are included (the site mentions pre-match and live with historical), and the API has dedicated endpoints for value bet detection and arbitrage identification. Closing odds are available. Futures and SGP (same game parlay) odds are not listed as supported.

One gap to note: Pinnacle is not covered. If your model prices against Pinnacle as a sharp anchor, you will need a separate feed for that. The Pinnacle API guide covers the alternatives.

Odds-API.io invests more in developer tooling than most competitors at this price point:

• Python SDK with async support, so you can run concurrent requests without blocking.
• Node.js/TypeScript SDK for JavaScript projects.
• MCP server installable via npx odds-api-mcp-server. This lets AI assistants (Claude, GPT-based agents, or custom agent frameworks) query live odds through the Model Context Protocol. If you are building an AI agent that needs to read the market, this is a plug-and-play integration. See the sports MCP servers page for the broader landscape.

The REST API returns JSON with sub-150ms average response times and a claimed 99.9% uptime SLA. WebSocket streaming is available as a paid add-on (it doubles your plan cost), delivering push updates with sub-100ms latency. Authentication uses an API key passed as a query parameter or header.

Pricing is in GBP and scales by bookmaker count rather than request volume (all paid plans share a 5,000 requests/hour base):

• Free (£0): 2 recreational bookmakers, 100 requests/hour (500/day). No card required. REST only.
• Solo (£49/mo): 2 bookmakers including a sharp and an exchange, 5,000 requests/hour. Email support.
• Starter (£99/mo): 5 bookmakers, 5,000/hour.
• Growth (£179/mo): 10 bookmakers, 5,000/hour. Priority support.
• Pro (£229/mo): 15 bookmakers, 5,000/hour. Priority plus phone support.
• Enterprise (custom): Unlimited bookmakers, unlimited requests, dedicated infrastructure.

WebSocket add-on: doubles the plan price (Solo + WebSocket = £98/mo, Pro + WebSocket = £458/mo). Capacity add-ons: £139/mo for 10K/hour, £229/mo for 20K/hour, £309/mo for 30K/hour.

The bookmaker-gated model means you choose which books you need. That works well if you only care about 2-5 sources, but costs add up fast if you need 15+ books with WebSocket. Compare the total cost against flat-rate providers that include all books in every plan.

The pricing and feature set point toward a few natural fits:

• Developers building AI betting agents who want an MCP-ready odds feed without writing custom integrations.
• Small projects and prototypes that start on the free tier and upgrade as the product proves out. The £0 entry point with no card is a genuine on-ramp.
• International coverage needs where Bet365, SBOBET, Betfair, and William Hill matter as much as the US books.
• Value bet and arbitrage detection using the built-in endpoints rather than computing edges yourself.

Skip it if you need Pinnacle data, SGP pricing, or futures markets. The bookmaker-per-plan pricing also becomes expensive at scale compared to providers that include all books on every tier. If you need 15 books with WebSocket, the Pro + WebSocket total (£458/mo, roughly $580) is competitive but not cheap.

Odds-API.io fills the middle ground between thin budget APIs and heavyweight enterprise feeds. The 265+ bookmaker count, free tier, official SDKs, and MCP server make it a solid choice for developers who want broad coverage with a low barrier to entry. The built-in value bet and arbitrage endpoints save you from writing that logic yourself.

The gaps are Pinnacle (not covered), futures, and SGP data. The per-bookmaker pricing model rewards focused use cases and penalizes broad ones. Start on the free tier, validate that the bookmakers and markets you need are actually present, and scale up from there. The 30% discount for SportsAPIs.dev readers (3 months) lowers the cost of finding out.
