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
- Open the StepFun site: platform.stepfun.ai
- Create an account and generate an API key.
- Paste it into the Dracon BYOK provider keys, stored encrypted (AES-256-GCM), used browser-direct, works in every Dracon tool.
Use your key in every tab
Two free extensions take the key you just set up. Both read the page you are on and use your own provider key: free, no account, nothing stored on a server we run.

Gotchas
Browser-direct chat is not available for this provider: We haven't verified its chat endpoints yet.. Dracon provider keys still cover it for tools that run elsewhere (for example a LiteLLM chain from the Dracon Router builder).
