StepFun API key setup

StepFun's open platform providing access to the Step family of large language models with reasoning and agentic capabilities.

Get your key

  1. Open the StepFun site: platform.stepfun.ai
  2. Create an account and generate an API key.
  3. Paste it into the Dracon key manager — stored encrypted (AES-256-GCM), used browser-direct, works in every Dracon tool.

Gotchas

Browser-direct chat is not available for this provider: Endpoint unverified — v2. The vault still stores its key for tools that run elsewhere (for example a LiteLLM chain from the router builder).
