  title: GPU Cloud API Keys API
  description: 'REST API of GPUcloud.ca: GPU plans, GPU servers (deploy, power actions, metrics, firewall), SSH keys and API keys. All prices are in CAD. Authenticate with a REST API key: `Authorization: Bearer `. AI agents should use the MCP endpoint (https://gpucloud.ca/api/mcp) with an MCP key instead. REST keys (prefix gpu_) are created in the console, expire after 90 days and are either full access or read-only (GET only; a read-only key gets 401 on any other method). Write requests (POST, PUT, DELETE) must also send the header `Origin: https://gpucloud.ca`, otherwise they get 403. Developer guide: https://gpucloud.ca/en/developers'

A server is never deleted while the account has credit left. When the balance covers only about 24 hours of what the account spends per hour, a first notice is sent while the servers still run, then two more about 24 hours and 1 hour before the deletion; a server is deleted with its data only once it is out of service (stopped or hibernated for lack of credit, or hibernated by the user for at least 72 hours), once the credit is exhausted (the balance no longer pays the next hour of the account''s servers), after the three notices and at least 24 hours after the first. Adding credits cancels the deletion. For the restart of such a server, minimumCad is the balance that restarts it (threshold + 0.01).'
