R231 is live: 77 standard calculations plus the Pro Nakshatra Timeline are available, with the 500-request Free allowance and globally serial durable jobs.
Billing controls your monthly API usage limits. All API access uses an API key.
Production includes 51 standard calculation endpoints on all plans, including the documented betas. Pro also unlocks the separate Nakshatra Timeline endpoint, for 52 endpoints in total. Paid plans increase allowances; existing prices and subscriptions are unchanged.
Calculate birth charts, houses, aspects, transits and synastry; use beta relocation charts, bounded astrocartography geometry, structured horoscope signals, chart SVGs, twenty-four Vargas from D1 through D150, Vimshottari with optional Pratyantardasha depth 3 and Sookshma depth 4, instant Panchang, Ashtakoota, Ashtakavarga with opt-in reductions and pindas, composites, uncorrected Davison charts, secondary progressions, solar arcs, lunar nodes and solar/lunar returns, and bounded planetary-event searches. Beta status and method-specific limits still apply.

Timeline calls use the separate Pro allowance: 1,000 units per UTC calendar month, one unit per admitted request, with a maximum interval of 180 days. Later errors or timeouts still consume reserved usage. Monthly quotas are separate from short-term rate/concurrency limits.
Opt-in mean Naibod solar arcs, Parashari graha drishti, eclipse observer snapshots, and text-only HTML report co-branding use the same route access and one-standard-unit accounting as their existing endpoints. They are included in every current plan; no new price or add-on applies.
Supported sidereal options are Lahiri, Raman, Krishnamurti, Fagan–Bradley, Yukteshwar, Sassanian, True Chitra, True Revati, True Pushya, Galactic Center at 0 Sagittarius, and Galactic Alignment/Mardyks. The six-star-only CC0 beta is included; asteroid and minor-body calculations are not offered. Natal analysis returns configured geometry without interpretation. Planetary hours use unequal sunrise-based intervals without electional advice. Relocation and astrocartography return bounded calculation data without interpretations, map tiles, rankings, or recommendations. The planetary-events beta searches bounded ingresses, stations and exact major aspects. The house-ingresses beta searches transit crossings of fixed Equal or Whole Sign reference cusps; it is not a moving-house calculation. The aspect-windows beta returns exact-hit-anchored orb intervals and optional iCalendar text. The separate Moon-phase beta provides phase sectors, illuminated fraction and bounded primary-phase calendars. Instant Panchang and lunar returns remain separate calculations. Eclipse shadows and crescent visibility are not modeled.
Plan, payment-method, and cancellation controls are securely hosted by Stripe. Subscriptions renew monthly until canceled, and cancellation takes effect at the end of the current billing period.
Note: The Nakshatra Timeline API currently supports intervals up to 180 days per request. Longer intervals are not currently offered. Quotas reset at the UTC calendar-month boundary, not the subscription renewal date.
