Sign In to Agent Relay Cloud

Use the existing OAuth device flow. No API key, invitation, dashboard wizard, or pre-existing Agent Relay account is required. Only the human approves the sign-in; never approve access on their behalf, ask for their password, or operate the approval page yourself.

Paths below are relative to the Cloud API base, https://agentrelay.com/cloud, including its /cloud prefix. When a guide names a different Cloud base (for example a local development stack), use that exact base throughout and never fall back to production.
