Legal
Terms of service
These terms govern your use of the Charter API, dashboard and the environment instances you lease through them.
Effective November 2, 2026.
1. Who these terms cover
"Charter", "we" and "us" mean the operator of the Charter service. "You" means the organization that holds the account and every person who uses it on the organization's behalf. By creating an account or calling the API, you accept these terms. If you sign a separate contract with us, that contract governs where it differs from these terms.
2. The service
Charter provides resettable instances of business software ("environments"), graded tasks and verifiers, through an HTTP API and a web dashboard. Each episode leases one instance for a limited time. When an episode ends or expires, the instance is destroyed and recreated from its seeded image, and anything done inside it is gone.
3. Accounts and API keys
- You sign in with a work email address. You are responsible for activity under your organization.
- API keys belong to your organization. Keep them secret. Revoke a key in the dashboard as soon as you suspect it has leaked. Calls made with your key before revocation are your calls.
- We may suspend a key that is being used in a way that threatens the service or other customers.
4. Acceptable use
You may use environments to train, evaluate and test software agents. You may not:
- Enter personal data about any real person into an instance. Environments hold synthetic tenant data only.
- Use an instance to send email, messages or payments to real people or systems outside the instance.
- Extract, copy or redistribute the environment software, its images or its seed data outside an episode.
- Attempt to reach other customers' instances, our infrastructure or the vendor's systems.
- Load-test the service beyond the slots you lease, or try to defeat lease limits or expiry.
5. Vendor software
Some environments are licensed to us by the companies that make them. Others are open-source software used under its own license. Your right to use an environment is limited to episodes through Charter. The software remains the property of its owner, and the owner's name and marks are used only to identify the environment.
6. Your data and outputs
Your agents, prompts, trajectories and results are yours. We record episode metadata (timings, status, task and verifier result) to run the service, meter usage and bill you. We do not use your agents or trajectories to train models. Our privacy policy describes what we collect.
7. Fees
Environment-hours are billed at the rate on our pricing page or in your contract, metered per minute from the moment an episode is ready to the moment it ends, with a one-minute minimum. Task-suite licenses are billed per environment per year. In v1 we invoice by hand under contract. Invoices are due within 30 days.
8. Availability and changes
We work to keep the service available, but we do not promise that a slot will always be free; when none is, the API says so and tells you when to retry. Environments may move between building, live and planned. We may change the API with notice in the docs; breaking changes to v1 come with at least 30 days notice to account owners.
9. Warranty and liability
The service is provided as is. To the extent the law allows, we disclaim implied warranties of merchantability, fitness for a particular purpose and non-infringement. Neither party is liable for indirect, incidental or consequential damages, or for lost profits. Our total liability for any claim is limited to the fees you paid us in the twelve months before the claim.
10. Termination
You can stop using the service at any time. We may suspend or end your access for a material breach of these terms, with notice where we can give it. Fees for usage before termination remain due.
11. Governing law
These terms are governed by the laws of the State of California. Disputes are resolved in the state or federal courts in San Francisco County, California.
