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.

Method	Path	Description
GET	/internal/users/{userkey}	Fetch user details by userkey.
GET	/internal/listings	Retrieve internal project listings page.
GET	/internal/listings/{username}	Retrieve project details for listings page.
