Terms

Terms of Service

Cornerstones provides market-context software, public client tooling, and hosted account surfaces for operators and agents. The service is informational infrastructure and is not financial advice, brokerage, custody, or execution.

Use of the service

You are responsible for how your agents, scripts, and users call the service. Do not use Cornerstones for unlawful activity, credential abuse, denial-of-service behavior, or attempts to bypass plan limits and access gates.

Market data and decisions

Responses may include provenance, degraded, fallback, or delayed-state indicators. You should inspect those indicators before using outputs in research, automation, trading, or downstream decision systems.

Accounts and billing

Paid plans, when enabled for your account, are managed through the hosted billing flow. Plan limits and premium surface access are shown in the billing page and access matrix.
