“Is there a tennis API?” is really three questions: what the tours publish, what the commercial market sells, and what is left for somebody who needs everything.
The tours publish pages, not APIs
The ATP, the WTA and the ITF all publish rankings, draws and results — as web pages for readers. They are authoritative for their own tour and they are not documented endpoints, and no one of them covers the others. A dataset spanning ATP, WTA, Challenger and ITF is a join across organisations that do not publish a joint product.
The commercial feeds
Comprehensive tennis data is sold. Those feeds are real, they are good, and they are licensed per use with prices set by negotiation rather than published on a pricing page. That makes adopting one a procurement decision with a contract at the end of it — which is the right answer for some projects and a non-starter for others.
Aggregators, and what robots.txt says
The remaining route is a results aggregator that already did the join. TennisExplorer is one, and its own machine-readable declaration is short. Checked on 9 September 2026, tennisexplorer.com/robots.txt declares a sitemap and disallows three paths: /redirect/, /terms-of-use/ and /contact/. The results, schedule, player and ranking pages are not among them.
Reading that file as a specification rather than a formality is the habit — robots.txt as a specification.
The line drawn inside the source
The same results table carries scorelines and bookmaker odds, and they are not the same kind of thing. A scoreline records an event that happened. The odds are supplied to the site by bookmakers as their commercial product, which is why this Actor ships with them off — the reasoning.
When to license a feed instead
When you need live in-play data, when you need a contractual guarantee of availability, or when you are redistributing the data as a product of your own. None of those is a scraping problem. Historical analysis, model training on finished matches and internal reporting generally are.
