Terms of Service
Last updated May 14, 2026
These terms govern your use of the hosted Arbiter platform at arbiter.run. By creating an account or using the service, you agree to them. Please read them — they cover how the beta works, how credits are billed, and the limits of what we promise while the platform is still stabilising.
The service
Arbiter is a hosted workspace and runtime for supervised, multi-agent workflows. Access is currently invite-only while the platform is in closed beta. Usage is metered and paid for with prepaid credits.
The Arbiter runtime itself is open source and may be self-hosted under its own licence; these terms govern the hosted service at arbiter.run, not your own deployments of the runtime.
Accounts
You are responsible for activity under your account and for keeping your credentials and API tokens secure. Tell us promptly if you believe your account has been compromised. You must provide accurate sign-up information and be old enough to form a binding contract in your jurisdiction.
Acceptable use
You agree not to use Arbiter to:
- break the law, infringe others’ rights, or generate content that does;
- attack, overload, or probe the platform or its infrastructure outside our disclosure process;
- resell or sublicense raw access to the hosted runtime as your own undifferentiated product;
- circumvent usage metering, rate limits, or access controls.
We may suspend or terminate accounts that violate these rules, and we may decline to process requests that put the platform or other tenants at risk.
Credits and billing
The hosted service runs on prepaid credits. Credits are consumed as you run requests, metered against token usage at the rates shown in your account. Purchased credits are non-refundable except where required by law. Unused credits do not constitute a cash balance and have no value outside the service.
Because the platform is in beta, pricing, rate cards, and included limits may change. Material changes will be communicated before they take effect.
Beta disclaimer
Arbiter is provided “as is” during the beta period. Features may change, break, or be removed; availability is not guaranteed; and data, while handled carefully, should not be treated as your only copy of anything irreplaceable. We disclaim warranties to the fullest extent permitted by law.
Limitation of liability
To the maximum extent permitted by law, Arbiter and its operators are not liable for indirect, incidental, or consequential damages, or for lost profits or data, arising from your use of the service. Our total liability for any claim is limited to the amount you paid for the service in the three months preceding the claim.
Termination
You can close your account at any time. We may suspend or terminate access for violations of these terms, for legal or security reasons, or if continuing to provide the service becomes impractical. On termination, your right to use the hosted service ends; data handling on termination is described in the Privacy Policy.
Changes to these terms
We may update these terms as the platform evolves out of beta. The “last updated” date above always reflects the current version; continued use after a change constitutes acceptance of the revised terms.
