# The best tennis API for what you are building

> There is no single best tennis API — there is the one that fits your job. Which plan covers live scores, point-by-point history, market prices or win-probability, what a first call returns, and how to verify any of it yourself.

## Which plan fits what you are building

- **A live scoreboard or a bot that reacts to scores** → Free ($0, no card). Live matches with sets, games, points, server and tiebreak state; fixtures; players. Enough to build and ship the read side before you pay anything.
- **Backtesting, research, or anything that needs what already happened** → Basic ($9.99/mo). Adds completed results, the point-by-point record, the 1968–2022 results archive, head-to-head and career aggregates.
- **Pricing models and anything that needs the market’s view** → Pro ($29.99/mo). Adds match events, match-winner prices with history, and rank-ordered ranking tables.
- **In-play trading, model serving, or a feed you subscribe to rather than poll** → Ultra ($99.99/mo). Adds AI win-probability, in-play statistics, per-player as-of rankings, rally construction and the push feed.

## Questions people ask

**What is the best tennis API?**

It depends on what you are building, and anyone who answers without asking that is guessing on your behalf. If you need live in-play data over REST or a push feed with a free tier that needs no card, Live Tennis API fits. If you only need finished results for offline research, you may not need a live API at all. The honest way to decide is to run your own workload against a free key before you pay.

**Is there a genuinely free tennis API?**

Live Tennis API has a permanent free tier, not a countdown trial: live matches and scores, fixtures, tournaments and players, with published limits and no card. A trial measures how fast you can integrate. A free tier measures whether the data is any good, which is the question you are actually asking.

**Which tours does it cover?**

ATP, WTA, Challenger and ITF, singles and doubles. The live feed is identical on every plan — no tier sees more matches than another. What the paid tiers add is depth: history, market prices, per-point events and the model, not extra matches.

**How do I check the latency claims myself?**

Ask for two timestamps on every push frame. Live Tennis API carries the event timestamp and a publication stamp, so the gap between them is our processing time and your own receive clock minus the publication stamp is transport. A feed with a single timestamp cannot be checked from outside, whatever number it advertises. The method and our own measured figures are published at besttennisapi.com.

**Can I start without talking to sales?**

Yes. Every plan is self-serve with an instant key, prices are published, and you can cancel from the portal. There is no call to book and no quote to wait for.
