Klaus Platform API is published by [Klaus AI](https://apis.io/providers/klaus-ai/) on the [APIs.io](https://apis.io/) network. Tagged areas include AI Agents, Instances, Integration, Models, and Sessions. The published artifact set on APIs.io includes authentication docs.

The Klaus platform API at api.klausai.com is a tRPC RPC surface used by the first-party @klausai/cli command-line client to manage OpenClaw instances, agents, integrations, models, and chat sessions, plus an OpenAI-compatible chat-completions proxy at /openclaw/v1/chat/completions for sending messages to an agent. Requests authenticate with an x-api-key API key created at klausai.com/account, or with a bearer session token obtained through the OAuth 2.0 Device Authorization Grant. The active instance is selected with an x-klaus-instance-id request header. Klaus publishes no OpenAPI description of this surface; the operations catalogued here were read from the provider's own published npm client bundle.
