Pricing FAQ

Common questions.

One governed action: a wrapped model completion, an MCP tool call, or an action your backend submits through the SDK or API. Policy checks, MAST classification, and the audit write are all included in that one event; you are never billed separately for the governance work around it.

Yes. Upgrades take effect immediately. Downgrades to Free and switches between monthly and annual billing are self-serve from the billing page, with no call required. Your audit data is retained according to the plan you move to.

There is no time-boxed trial because the Free tier is permanent. You can run a real agent on Free with 50,000 events a month, then upgrade to Pro when you need more agents, longer retention, or compliance reports. Cancel anytime.

Annual billing saves 17% versus monthly. If you are an early-stage startup or a nonprofit deploying agents in a regulated space, contact us; we would rather have you governed than priced out.

On Free, ingestion pauses at the 50,000-event hard cap until the next month; nothing is silently dropped without telling you. On Pro, events past 2,000,000 are metered as overage on your next invoice. RedScan and ProvenanceGuard beyond your monthly quota run on prepaid credit packs (5 for $249, 10 for $449, 25 for $999) that roll over and never expire.
