Common questions

What counts as a "request"? +
A request is any API call your agents make to OpenAI or Anthropic. Each message sent to a model counts as one request, regardless of token count. Token costs are tracked separately.
Can I change plans later? +
Yes. Upgrade anytime — changes take effect immediately. Downgrading takes effect at the end of your billing period. No contracts.
Do you store my API keys? +
Yes, but encrypted with AES-256-GCM. We need them to pull usage data from OpenAI and Anthropic on your behalf. You can revoke them at any time.
What happens if I exceed my plan limits? +
You'll see a notification in the dashboard. Your data won't be deleted, but syncing new usage may pause until you upgrade or the next billing cycle starts.
Is there an annual discount? +
Not yet, but it's on the roadmap. Email us at hello@costline.app if you want to discuss annual pricing for your team.
