Questions
What does this actually cost me?
The free tier covers 10,000 actions a month — about 300 a day, which is more than most single agents use, and it does not expire. Past that it is $40 per million actions: an agent doing 1,000 actions a day costs about $1.20 a month. There is no subscription and no minimum, so an agent that does nothing costs nothing.
What counts as an action?
Every API call to /v1/* counts as one. Creating sessions, checking permissions, storing secrets, logging audit entries — each is one API call, and reads count too.
What happens if I exceed my limit?
On the free tier, calls return a 429 until the month rolls over — nothing is lost and no session is terminated. On the metered plan there is no ceiling to hit: calls keep working and cost $40 per million.
Can I change plans anytime?
There is nothing to cancel. The metered plan has no subscription and no minimum, so you stop paying by not making calls — an idle agent costs nothing. If you are on the free tier, there is nothing to downgrade from.
Do you offer annual billing?
