What developers say
Widely used for pulling bookmaker odds into fantasy tools, arbitrage scanners and betting models; many GitHub repos and tutorials build on it. Users like the free tier and breadth of markets and books. Complaints: modest refresh rate, historical odds limited to one day per call and gaps in snapshots, no prop results or match outcomes, some books paid-only.

2. nba_api (NBA Stats)
Free / open data
MIT-licensed Python package wrapping many unofficial NBA.com stats endpoints, returning data for games, players and teams; not an official or hosted API.
Free tierLive data80 discussions6.3k GitHub reposMixed
63Score
What developers say
Unofficial Python wrapper around NBA.com stats endpoints, widely used in Reddit data-viz posts, tutorials and many GitHub projects. Users like the clear docs and easy start, but report that NBA header changes break endpoints, timeouts occur, and 2025-26 pulls stopped working for some. Alternatives mentioned: balldontlie, API-Sports; commercial use raises legal questions.
Liked
- + Easy to use with good docs
- + Large community and many projects built on it
Watch out
- − Breaks when NBA changes headers or blocks requests
- − Bulk pulls are slow or time out

3. Riot Games API
Esports data
Official Riot Games developer API giving League of Legends player, match-history, ranked and live-game data, with free developer keys and a production approval path.
Free tier70 discussions2.9k GitHub repos
56Score
What developers say
Official Riot API for League of Legends, TFT and Legends of Runeterra data, with free dev keys. Mentions are mostly old announcements: launch, an early scraping ban pushing developers to the API, match-history deadlines, and API challenges. Libraries such as Cassiopeia show lasting use, but there is little recent user opinion on limits or quality.
Liked
- + Official API with free developer keys
- + Long-lived community libraries and contests
Watch out
- − Scraping not allowed, API-only policy

66Score
What developers say
Very widely used for football side projects, prediction models and live-score apps, praised for broad league coverage, decent docs and low price (about $19/month).

5. NBA Stats (stats.nba.com)
Free / open data
Undocumented public JSON endpoints behind the NBA's stats website, giving current and historical team and player statistics. Unofficial use, no key and no stability guarantee.
Free tier60 discussions152 GitHub reposMixed
45Score
What developers say
Undocumented stats.nba.com JSON endpoints, mostly reached through community wrappers like nba_api and py_ball. Popular for charts and models, but the NBA has restricted access over time (header requirements, removal complaints, users reporting being blocked or timing out). No official docs or support; people lean on wrappers or alternatives like Basketball Reference.
Liked
- + Rich historical player and team stats
- + Wrapper libraries make it easy to use
Watch out
- − Undocumented and unofficial
- − Access restricted or blocked over time

Betting exchange
Prediction market exchange whose public Gamma API lists markets and events, including sports, without credentials; separate trading APIs and SDKs exist.
Free tier52 discussions4.5k GitHub reposMostly positive
67Score
What developers say
Widely used as a free, no-key source of prediction-market prices (Gamma and CLOB APIs) for sports arbitrage bots, wallet trackers and odds aggregators, with many GitHub clients and MCP servers. Users note thin or missing historical data and the need to match events across Kalshi and sportsbooks; live-score speed is a concern.
Liked
- + Public market data without credentials
- + Large ecosystem of SDKs and bots
Watch out
- − Historical data hard to find, especially before 2024
- − Manual cross-venue event matching

39Score
What developers say
Used by hobbyists to pull their own fantasy league data for dashboards, bots and analytics, with community wrappers in Node, Go and Python. Developers struggle with OAuth setup, XML-only responses, thin docs and missing fields such as projections or stats. Access is limited to approved apps and rate-limited.
Liked
- + Access to own league, roster and transaction data
- + Community wrappers in several languages
Watch out
- − OAuth flow is confusing and poorly documented
- − Responses are XML by default

What developers say
Commercial provider widely used for US sports, especially NFL fantasy tools that pull projections and stats from it. A free trial key makes prototyping easy. Developers on a budget repeatedly call it and Sportradar too expensive, and one user reported inaccurate season stats. Hobbyists look at JsonOdds or MySportsFeeds instead.
Liked
- + Free trial key for prototyping
- + Strong US sports and fantasy projections coverage
Watch out
- − Too expensive for bootstrapped projects
- − Reported inaccurate player season stats

What developers say
Widely used paid football data API for side projects, dashboards and betting models, with many wrappers and GitHub repos. Users like the stats depth and reasonable price versus Opta or Sportradar, but call it pricey for hobby use, say premium odds lack player props, and report unreliable live data and sales or custom-plan frustrations.

- + Cheaper than Opta or Sportradar

What developers say
Seen as the benchmark enterprise sports data supplier, used via trial keys in hobby projects, wrappers and tutorials. Developers repeatedly call it too expensive (thousands per month), opaque on pricing, sometimes unwilling to sell to small buyers, and not fast enough for live use. Common cheaper alternatives mentioned: SportsDataIO, Genius, Opta, Sportmonks.
Liked
- + Broad sport coverage and depth
- + Regarded as the reference provider
Watch out

Betting exchange
Regulated prediction-market exchange whose API gives access to event-contract markets, order books and trading over REST, WebSocket and FIX; sports contracts are among its markets.

49Score
What developers say
Regulated prediction-market exchange with REST, WebSocket and FIX access; sports contracts are used by many arbitrage and trading bots, with clients in C++ and others. Users note the historical API lacks order-book depth, and live-score milestones can show goals later cancelled by VAR. Often paired with Polymarket aggregators.
Liked
- + REST, WebSocket and FIX access
- + Settled markets, trades and candlesticks available
Watch out
- − No historical order-book depth for backtesting
- − Live score milestones may reflect cancelled goals

What developers say
Popular free-tier choice for hobby football projects: World Cup predictors, score trackers, league tables, and a fallback when API-Football quota runs out. Developers like the free key and simple docs. Complaints: free tier gives fixtures and final scores but no shots, xG or lineups, history starts around 2019, and a low request rate.
Liked
- + Free API key good for fixtures and results
- + Frequently chosen for side projects
Watch out
- − No detailed match stats or xG on free tier

What developers say
Used for Bet365 live and prematch odds, with several community SDKs and crawlers on GitHub. Users call the site unpolished, cap event history at 20 games, lack live bet settlement, and charge steeply for Bet365 access. A 2026 complaint says a change in odds scraping broke years of historical continuity. Docs flagged as thin. Alternatives sought include Pinnacle-history providers.
Liked
- + Offers Bet365 odds feed
- + Community SDKs in Python and Laravel
Watch out
- − Pricey for Bet365 access
- − History limited to 20 games
