# Is the contract machine-readable, and is it kept honest?

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

A published OpenAPI document that matches the live service, maintained client libraries, and reference documentation a machine can read without executing JavaScript.

## Why it separates providers

A spec that has drifted from the service is worse than none — it generates clients that compile and then fail. Documentation that only renders in a browser is invisible to the agents your users increasingly ask instead of reading docs.

## The test you can run

Fetch the OpenAPI document, generate a client from it, and call three endpoints. Then fetch the reference page with JavaScript disabled and see whether any of it is there.

## What Live Tennis API measures

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