# Versions

> Versioning Policy for the Axiom Proving API

The Axiom Proving API is versioned and available at `api.axiom.xyz/{version}`.
For any given API version, we will preserve:

* Existing input parameters
* Existing output parameters

However, we may do the following:

* Add additional optional inputs
* Add additional values to the output
* Change conditions for specific error types

Generally speaking, updates to a given API version will be backwards compatible.

## Version History

We always recommend using the latest API version whenever possible. Previous versions
are considered deprecated and may be unavailable for new users. At present, `v1` is the
only API version.
