# API Keys

Manage project-scoped API keys (`vilna_api_...`) used to authenticate the public Vilna API (`api.vilna.io`). A project must exist before a key can be created. The raw secret is returned only in the create response.

 - [GET /workspaces/{workspace_id}/projects/{project_id}/keys](https://docs.vilna.io/ru/apis/mgmt/api/api_key/list-workspace-project-keys.md): Return project API keys.
 - [POST /workspaces/{workspace_id}/projects/{project_id}/keys](https://docs.vilna.io/ru/apis/mgmt/api/api_key/create-workspace-project-key.md): Create a new project API key. The raw secret is returned once and cannot be retrieved again.
 - [GET /workspaces/{workspace_id}/projects/{project_id}/keys/{key_id}](https://docs.vilna.io/ru/apis/mgmt/api/api_key/get-workspace-project-key.md): Return a project API key by ID.
 - [POST /workspaces/{workspace_id}/projects/{project_id}/keys/{key_id}/actions/revoke](https://docs.vilna.io/ru/apis/mgmt/api/api_key/revoke-workspace-project-key.md): Revoke a project API key. Once revoked, the key can no longer be used for authentication.
