    Running AI is easy. Defending it later is the hard part.

    Your AI will eventually be questioned. A partner, an auditor, a regulator, or your own team will ask: what did the system actually do? The difference is whether you have independently verifiable evidence or just logs.

    NexArt does not charge for execution. You pay for independent certification: the part that turns a run into something you can stand behind later.

    What changes when a run is independently certified

    Without independent certification

    • Evidence depends on internal logs you control
    • Auditors and partners must take your word for it
    • Incident reviews start with "what do we have?"
    • Governance conversations rely on process claims, not proof

    With NexArt certification

    • Every run produces a tamper-evident, signed record
    • Anyone can verify independently. No account needed
    • Incident reviews start with cryptographic evidence
    • Governance conversations reference verifiable artifacts

    What you are paying for

    Execution is always free. Generate Certified Execution Records locally using the SDK and CLI at no cost.

    Paid plans add independent certification via the NexArt attestation node: the infrastructure layer that transforms a local record into something a third party can verify without trusting you.

    A certified run is one Certified Execution Record processed by the NexArt attestation node and returned with a verifiable proof. It includes canonical execution proof (CER), a verifiable certificate hash, an independent attestation signature, and tamper-evident integrity that can support later audit review.

    What becomes easier

    Once your AI executions are independently certified, several things that used to require effort become straightforward.

    • Responding to audit requests with verifiable artifacts instead of exported logs
    • Defending AI-driven decisions when challenged by partners or regulators
    • Onboarding compliance teams without building custom evidence pipelines
    • Reducing time spent on incident review and root cause analysis
    • Earning trust from customers and stakeholders who need more than your word

    Account-level enforcement

    Quotas are enforced at the account level by the NexArt attestation node.

    • Limits are shared across all API keys in an account
    • API keys do not increase usage limits
    • Explicit caps for Free / Pro / Team
    • No surprise bills
    • Enterprise usage governed by contract

    Note: API keys are used for authentication and environment separation only. They do not carry quota. Creating additional API keys does not increase your monthly limit.

    What we never charge for

    You are not paying to use NexArt locally. You are paying for the independent certification layer that makes your evidence verifiable by others.

    • SDK
    • CLI
    • Local execution
    • Local CER generation
    • Independent verification

    Upgrade philosophy

    Same SDK. Same CLI. Same code.

    Paid plans unlock assurance, not features. No refactor required.
