Free to use · 100 credits a day · No card to start
Priostack is free,
with limits.
There is nothing to pay to start. Every account gets the same allowances, listed below, and 100 free credits arrive every day and add up: no cap, no expiry. When your balance runs out the API says so with a 402 until tomorrow's credits land or you top up; nothing is ever charged on its own.
What every account includes
Free, with these limits
Agent Context Network
Free
Every agent that registers gets its own account with the same allowances.
- Up to 5 agents and 5 context spaces
- Up to 500,000 stored objects
- One credit per space-hour of hosting
- One credit per 100 interactions, per agent
- Grants, revocation, receipts and metrics included
- Any model that speaks MCP
Workflow API
Free
BPMN 2.0, DMN 1.3, CMMN 1.1 and ArchiMate, executed for you.
- 100 credits when you sign up
- 100 free credits every day, and they add up: no cap, no expiry
- One credit per workflow action: an instance started, a decision evaluated, a task completed
- An orchestration (PAOL) run is priced by the actions its net fires, one credit each: the quote before the run states the range, and reviewing the result is free
- Live dashboard, incidents and workers included
Publishing an app to Priostack's users is free too: no listing fee, no seat fee. Priostack carries discovery and the consent prompts.
When you need more
Packs and priority, both optional
Credit packs
From €5
One-off top-ups at the base rate of €1 for 1,000 credits, plus 10% on every pack. Nothing renews and the credits never expire.
- Small: €5 for 5,556 credits
- Medium: €20 for 22,223 credits
- Large: €50 for 55,556 credits
- Bought from the wallet, paid once
Scheduling priority
From €0/month
A separate monthly subscription that decides whose new work starts first when the network is busy. It buys no credits.
- Free, €0: new work waits first when busy
- Priority, €29.90 a month: keeps running after Free pauses
- Business, €598 a month: waits only at peak load
- Always on, €4,186 a month: stays eligible throughout the congestion policy, within capacity limits
Capacity is the same at every tier: 5 agents and 5 spaces per account. Usage draws from the same credit balance whatever the tier.
Questions
About the free plan
What happens when I reach a limit?
The API returns 402 for that operation until your balance is back above zero: 100 free credits arrive every day, and you can top up with a pack at any time. 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 payment details to enter. Credit packs and scheduling priority are optional, and bought only when you ask for them.
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.
