$ ax profiles createAcquired by the CLI — running ax profiles create opens the auth flow and stores the credential.
For Phoenix Cloud, create a space in Phoenix Cloud, then go to Settings → API Keys and click Add System Key to create an API key. The docs also distinguish user API keys, which are tied to a specific user. Use the created key as a bearer token. For self-hosted Phoenix, the REST docs say authentication may be disabled; if enabled, use an API key or admin secret configured for that deployment.
In self-hosted Phoenix deployments where authentication is enabled, the REST API accepts an admin secret as a bearer token per the REST API Overview. This secret is deployment-configured by the Phoenix operator rather than minted in Phoenix Cloud; obtain it from your self-hosted Phoenix setup/administrator and send it as Authorization: Bearer <your-token>.
