Key introspection
GET /v1/key - what the routing key in the Authorization header can do, without dashboard access.
Read as MarkdownGET /v1/key
Auth: routing key (pllm_…) - the key introspects itself. Built for automated agents that need to confirm what a key routes to (a Codex subscription or plain API keys), which models it can reach, and how much budget is left. Never returns credential secrets.
