   1. Live Tennis API

   Sports data API

   Tennis API for ATP, WTA, Challenger and ITF with live point-by-point scores, match history, market odds, rankings and an AI win-probability field, over REST and WebSocket.

   56Score

   What developers say

   Tennis feed (REST and WebSocket) with point-by-point scores, odds and win probability. Most mentions are vendor-authored issues and promotions. A few independent users say they use it for tennis models or a match-simulation app and find the data detailed, but there is no real feedback on price, reliability or latency.

   53Score

   What developers say

   Tennis API with livescores, fixtures, odds and WebSocket, used in around thirty small GitHub projects and tutorial apps. Users describe it as pricey compared with RapidAPI options, and one developer found it only a results feed, with no draw sheet, seeds or bracket positions. Compared with Matchstat; little other direct feedback.

   Long-popular free NBA stats API, now covering NBA, NFL, MLB and EPL with a free tier and paid keys.

   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.

   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.

   Little real discussion exists. Nearly all hits are the generic phrase 'all sports' or Indian resellers' promo videos. Only a couple of directory listings and a few small GitHub apps for live scores reference allsportsapi.com. Nothing is known about pricing, quality or reliability from users.

    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.

    What developers say

    Odds and scores API with a free tier, offered directly and via RapidAPI. Very little real discussion: one old Stack Overflow question about a 404 and a few repos, including a sportsbook ingestion service and an odds API benchmark that lists it among rivals. No user opinion on quality or price is available.

    What developers say

    Aggregated odds API with broad bookmaker claims, used in side projects and sportsbook prototypes, and listed in MCP/agent tool collections. User feedback leans negative: live odds delayed by roughly 10 seconds or more, many UK bookmakers shown inactive, and Pinnacle support dropped in January 2026. Seen as an alternative to The Odds API and OpticOdds.

    Cricket-first provider used in a number of hobby cricket and IPL score sites, with a community SDK on GitHub. The one user opinion says it covers part of what a developer wanted for deep cricket stats but not all. Other hits are vendor-style posts; nothing on pricing, reliability or support.

    Crowd-sourced sports database popular for hobby apps, tutorials, student projects and Plex metadata agents, with many wrappers in several languages. Praised as free and good for artwork.
