Questions
Does an xAI API key cost extra?
Yes, a key bills per request. Threadlines keeps a stray XAI_API_KEY in your environment away from your subscription sign-in, so you don't pay by accident.
Which access levels does Grok support?
Approval required, Auto and Full access. Grok has no accept-edits-only mode.
What does it cost?
Threadlines is free and MIT-licensed. You pay xAI for your Grok plan, or per request with an API key.
Other agents
Grok is made by xAI. Threadlines is an independent open-source project and isn't affiliated with or endorsed by xAI.
