The Sports vertical on apis.io has 233 member providers, and every one of them has a profile file behind it. Only 3 of them score strong on the Kin Score, and nobody reaches exemplar. All three of the strong ones sell odds. The leagues that own the games sit at the bottom of the table. The National Basketball Association and the National Football League each score 3.4, minimal.
One caveat before the numbers. The industry page header claims 938 APIs. Add up the published api_count across the 233 provider files and you get 255. The header counts every API page, and it is a known mismatch (roadmap#796). Everything below comes from the member rows.
Who holds the vertical
| Band | Providers | Examples (Kin Score) |
|---|---|---|
| Odds and betting data | strong | Odds API 58.9, ParlayAPI 58.9, 5DollarFootballAPI 58.0 |
| Fan and media platforms | developing | LiveLike 50.0, StubHub 49.3, WSC Sports 42.9 |
| Official data distributors | thin | Sportradar 36.0, Stats Perform 33.5, Genius Sports 26.6 |
| Leagues and governing bodies | minimal to emerging | MLB 18.1, NHL 15.3, Formula 1 7.9, FIFA 3.1 |
Across all 233 rows the band counts are 114 minimal, 55 emerging, 40 thin, 19 developing, 3 strong, and 2 unscored. On Agent Readiness, 149 are human-only and only 5 are agent-native. Odds API is one of those five.
What the record says
The leagues are rich in data and absent from APIs. The industry’s demand signal ranks the NBA at 60 and the NFL at 54 for technology adoption. Both score 3.4 on the Kin Score and publish no API the catalog can count. That is not a contradiction. Leagues sell their data through rights deals, and a public developer surface is not what those deals are built to produce. But it means an agent asking for official league data finds nothing first-party to call.
The official distributors are the thin middle. Sportradar, Stats Perform and Genius Sports hold the rights the leagues license out. They score between 26.6 and 36.0, all in the thin band. Their surfaces sit behind sales-led access, and the rubric measures what is public.
The betting startups built for developers, and for agents. The vertical’s highest scores belong to small, OpenAPI-first odds providers. Odds API describes itself as OpenAPI-first, with SSE and WebSocket streaming, an MCP server, llms.txt and agent instruction files. It also scores 44.0 on Agent Readiness. These companies have no rights to protect. They compete on being easy to integrate, and the score shows it.
Where to start
If you are building on sports data today, start with the odds providers for live markets, The Racing API (40.2, agent-native) for racing, and Sportmonks (50.2) for football fixtures and statistics. Then expect a commercial conversation with a licensed distributor once you need official data.
Takeaway
What would move this vertical is one league publishing even a read-only schedule and results API, with an OpenAPI contract behind it. Until one does, the best-scored sports data on the network belongs to the companies betting on the games, not the leagues that play them.
