Each market counts once, however many leagues carry it. Other markets are the provider's own market labels that we have not matched to our market names yet. The extra book and league labels come straight from the provider and are not matched to our book and league names yet. These labels still count in the totals.
Live odds: yes, per the provider's docs.
What Odds-API.io Is
Odds-API.io is a sports odds API that aggregates 450+ 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. New free API keys are paused indefinitely, so Solo is the entry plan for new users.
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.
Coverage and Market Types
The numbers on paper are strong: 450+ bookmakers, 34 sports, 500+ 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.
- Sports: The site names the NFL, college football (NCAAF), the NBA, college basketball (NCAAB), MLB, the NHL, tennis (ATP and WTA), and soccer leagues such as the Premier League, La Liga, Serie A, Bundesliga, Champions League, and MLS.
- Market types: Pre-match and live odds across moneylines, spreads, totals, and the rest of its 500+ 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.
SDKs, MCP Server, and Developer Experience
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 stated 99.9% uptime target. 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 the apiKey query parameter.
Odds-API.io Pricing and the Paused Free Tier
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), REST only. New free API keys are paused indefinitely. Existing free keys keep working.
- Solo (£49/mo): 2 bookmakers of your choice, 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. Dedicated 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.
Getting an API Key
Odds-API.io has paused new free keys, so a key starts with a paid plan. Pick one on the Odds-API.io pricing page and pay by card, PayPal or, on a monthly plan, crypto. The key arrives by email straight after payment. The pricing page lists no trial. Our link carries the referral that takes 30% off the first 3 months of a monthly card plan, while annual plans get 2 months free instead (checked November 2026).
Every authenticated call takes the key as the apiKey query parameter. Three lookups need no key at all, /v3/sports, /v3/bookmakers and /v3/markets, so you can read the book list and the market names for your sport before you buy. Once the key works, choose your books with PUT /v3/bookmakers/selected/select. Solo takes 2 of your choice. Pick with care, because the API lets you clear that selection only once every 12 hours.
A First Request in Python
The docs quickstart makes this call as its third step: GET /v3/events on https://api.odds-api.io/v3 with sport=football (soccer), a limit of 10 and the key as apiKey. The sample comes from the docs, checked November 2026.
import os
import requests
resp = requests.get(
"https://api.odds-api.io/v3/events",
params={
"apiKey": os.environ["ODDS_API_IO_API_KEY"],
"sport": "football",
"limit": 10,
},
timeout=15,
)
resp.raise_for_status()
for ev in resp.json():
print(ev["id"], ev["league"]["name"], ev["home"], "v", ev["away"], ev["date"])Back comes a JSON array. Each event has a numeric id, a league object with name and slug, home, away, a date and a status. With no to parameter the list covers the next 14 days. Feed an id to GET /v3/odds as eventId, along with your bookmakers, to get prices, or send up to 10 IDs to /v3/odds/multi for the cost of one request.
Rate Limits, Docs and SDKs
Paid plans share one limit, 5,000 requests an hour, and existing free keys keep 100 an hour, capped at 500 a day (checked November 2026). Each response carries x-ratelimit-limit, x-ratelimit-remaining and x-ratelimit-reset, an ISO 8601 time. Go over and you get a 429 with an error message in the JSON; the docs say to back off until that reset time. The cheapest way to stretch the hour is /v3/odds/multi. The WebSocket allows two connections per key, and a third closes the oldest.
The official SDKs are odds-api-io on PyPI, with sync and async clients, and odds-api-io on npm, both with source on GitHub. The docs carry an OpenAPI spec at /api-reference/openapi.json, the whole reference in /llms-full.txt and a dated changelog; its newest entry, on October 29, 2026, added 30 Italian sportsbooks. The status page showed 99.99% uptime for the REST API. Support runs by email at hello@odds-api.io.
Who Odds-API.io Is For
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 can start on Solo at £49/mo and move up as the product proves out. New free keys are paused, so there is no £0 on-ramp for new users.
- 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.
If you need Pinnacle data, SGP pricing, or futures markets, it pairs well with a separate Pinnacle-focused feed or a general aggregator from the directory. 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.
Verdict
Odds-API.io fills the middle ground between thin budget APIs and heavyweight enterprise feeds. The 450+ bookmaker count, £49 entry plan, official SDKs, and MCP server make it a solid choice for developers who want broad coverage at a moderate entry price. 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 Solo, 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.
