Live now
Astrology APIs, open for builders.
Generate charts, Panchang data, Dashas, transits, matching inputs, and structured astrological outputs through a developer-friendly API layer.
POST/v1/chart
Birth chart calculations
Rasi, Navamsa, and divisional charts with deterministic planetary positions.
GET/v1/panchang
Panchang and lunar data
Tithi, vara, nakshatra, yoga, karana, and sunrise/sunset for any location.
POST/v1/positions
Nakshatra and planetary positions
Sidereal positions, retrogrades, declinations, and nakshatra padas.
POST/v1/dasha
Vimshottari Dasha

POST/v1/transits
Transit calculations
Current and forward planetary transits relative to a natal chart.
POST/v1/match
Compatibility inputs
Structured inputs for Ashtakoot, Dashakoot, and other matching frameworks.
In training
A practitioner-guided intelligence system.
We are training and evaluating a domain-adapted model on a large historical prediction corpus, supported by review from senior traditional practitioners. The system is being designed for structured reasoning, empathetic language, and tradition-consistent interpretation.
Corpus
Anonymized historical predictions with practitioner annotations.
Review
Sampling-based human review for tradition consistency.
Evaluation
Chart consistency, specificity, empathy, contradiction rate, safety.
Method
Built as a measurable system.
Our work separates deterministic chart computation from interpretive generation. Outputs are evaluated for chart consistency, specificity, empathy, contradiction rate, and safety boundaries.
- 01Deterministic chart contextCalculation layer is the source of truth. All interpretive output is grounded in structured chart facts.
- 02Anonymized training corpusHistorical predictions reviewed for traditional consistency, with personal identifiers removed.
- 03Practitioner review loopsSenior traditional practitioners review samples for tradition-consistent interpretation.
- 04Model evaluationOutputs scored on chart consistency, specificity, empathy, contradiction rate, and refusal behavior.
- 05Safety and refusal boundariesDefined boundaries for medical, legal, financial, and emergency-adjacent topics.
Quickstart
First API call in minutes.
Generate a token, send a single request, receive structured chart output. The same endpoints power our internal evaluation harness.
