As recorded at collection: Free sharing of a StepFun(스텝펀) API authentication key

The StepFun(스텝펀) API access URL is https://api.stepfun.com/step_plan/v1. The authentication key published in the post is encoded in base64 (a way of representing a string in another form). The service is accessed with these credentials, without a separate signup process or review.

The shared base64 string is decoded back into its original string and set as the API key, and the URL above is configured as the request URL. The post contains only two lines, the URL and the key, and provides no separate instructions on setup or a list of available models.

It has not been disclosed whether the poster published their own key or how they obtained it. If the key owner or service operator discovers that it has been exposed, they may invalidate it immediately, interrupting access without notice. Usage limits, expiration date, and permission to use it need to be confirmed. Using publicly exposed authentication information without permission may violate the service terms.
