## Deprecated Endpoints

These endpoints will be removed after the advertised date. We will do our best to notify consumers (by their advertised `X-Ethos-Client` header) in advance of removal.

## Beta Endpoints

Beta endpoints are recent additions and are still subject to rapid change without further notification to consumers. We will remove the 'beta' tag once they are stable.

***

## Internal Endpoints

Internal endpoints are used by Ethos frontend and are not intended for public consumption. They may change without notice. We intend to 'publish' them to beta status.
