# Can you evaluate it properly before paying, without a card?

> besttennisapi.com is operated by JSB Holdings LLC, which also operates Live Tennis API. This site is not independent.

A permanently free key with published limits that lets you run your real workload against real fixtures — not a countdown trial that expires mid-evaluation.

## Why it separates providers

A trial measures how fast you can integrate. A free tier measures whether the data is any good. Only one of those is the question you are actually asking.

## The test you can run

Sign up without a card, then run the calls your product would actually make and read the rate-limit headers. Check whether the limits are published as numbers or described as 'generous'.

## What Live Tennis API measures

**Not yet measured.** No figure is published for this criterion.
