Somewhere right now a founder is waking up to an API bill they weren't expecting. Agentsitter exists so that founder isn't you.
Your API key is landing now. Check spam if you don't see it in 30 seconds.
Nobody noticed. Nobody got an alert. The bill quietly accumulated while the team assumed everything was running fine.
Agentsitter would have caught it on day one. The moment costs stopped looking normal, the founder would have had a text. Not a $47,000 invoice.
