How Usage Is Counted

— Normal API requests include birth charts, transits, aspects, houses, synastry, and other standard endpoints.
— Pro includes up to 100,000 normal API requests per month.
— The Nakshatra Timeline API is computationally intensive and tracked separately.
— Pro includes 1,000 Nakshatra usage units per month.
— Each timeline request of up to 180 days uses 1 unit.
— Requests stop at the included monthly limit; automatic overage billing is not enabled.
— All 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.
