GET /v1/modelsInstall in three steps
- Create a free account at 0n3.app and connect Cohere: paste a key or sign in through a door. It lands in your vault, encrypted.
- Open 0n3.app/install, pick your AI. A key is made for that AI alone; copy the line it gives you.
- Ask your AI: whoami. It answers with your connected services. Then ask it to generate in Cohere.
