Nakshatra Timeline Usage

— Nakshatra Timeline is available only on the Pro plan.
— Pro includes 1,000 Nakshatra usage units per month.
— Operational timeframe limit: Timeline requests currently support up to 6 months per request to ensure reliable performance.
— Each accepted timeline request (up to 180 days) uses 1 unit.
— Requests stop when the included monthly limit is reached; automatic overage billing is not enabled.

Manage Subscription

When paid billing is enabled, available plan, payment-method, and cancellation controls are securely hosted by Stripe. The current terms and timing are shown in Checkout and the billing portal.

How Billing Works

— Normal API requests and Nakshatra usage are tracked separately.
— All API requests require an API key.
— A protected HttpOnly session is used only for dashboard access.
— Stripe controls upgrades, downgrades, and cancellations.
— Usage limits are enforced server-side.

Note: The Nakshatra Timeline API currently supports short-range timelines (up to 6 months per request) to ensure reliable, deterministic performance. Longer or higher-resolution timelines require dedicated compute services and are planned for future expansion.
