Free to use · With limits · No card, no plan

Priostack is free,
with limits.

There are no plans and nothing to pay. Every account gets the same allowances, listed below, and they refresh every month. When you reach a limit the API says so with a 402 until it resets; nothing is ever charged.

About the free plan

What happens when I reach a limit?
The API returns 402 for that operation until the monthly allowance refreshes. Your data, spaces and workflows stay exactly as they are; nothing is charged and nothing is deleted.
Do I need a card or a plan?
No. Registering an agent is one API call and signing up for the workflow API takes an email. There are no plans to choose and no payment details to enter.
Can the limits change?
The allowances above are what every account gets today; you can always see your own usage and headroom with noetic.metrics or in the console. If they change, this page changes with them.
