CHECKINGv13.16.102026.08.24

Jyotish computation,
as infrastructure.

An ephemeris, a cited classical rule corpus, 5 dasha systems and 7 languages behind one MCP endpoint — the specialist work your product needs and your team should not have to build.

No Jyotish hire

The classical corpus is in the engine, cited rule by rule. Shipping a Jyotish feature does not mean staffing someone to check it.

No translation vendor

7 languages generated from one ontology and validated at build time — not a translation pass bolted on afterwards.

No PII liability

Never logged, never in an error message, never in our database. The computed chart may be cached — encrypted under a key derived from your own API key, so it is ciphertext even to us, and one parameter turns it off.

01Conversational surface

One call replaces your consumer pipeline.

One tool call runs the whole consumer pipeline — chart computation, classical grounding in BPHS, Phaladeepika and Saravali, generation, verification, localisation. The citations come from what the engine retrieved, not what the model claims it used. The rest of the product is yours to build.

Latency

Median turn ~3.7 s — chart computation, rule evaluation and validation included; 95% under 8.5 s. Opt-in streaming delivers grounding before prose.

Session memory

Per-session memory, namespaced per caller — no conversation store to build. For long threads, your compacted summary supersedes it; the engine stores nothing.

Your model

The generating model is configuration, not architecture — providers sit behind one registry. On the Custom tier: your key, your routing, your account.

Crisis gate

Crisis-tier messages never reach a model — classified and stopped in the pipeline, not the prompt. Your product simply receives the signal.

Verified claims

Placements and aspects asserted in the prose are checked against the computed chart; contradictions never ship. A guardrail that knows the answer.

Seven languages

English, Hindi, Sanskrit, Tamil, Telugu, Kannada, Bengali. The ontology is multilingual at the root — classical vocabulary native, not transliterated. Pinned per conversation.

Streaming is additive — the terminal frame is an ordinary JSON-RPC response, so a client that ignores it works unchanged.

Output your agent uses as-is.

04Classical depth

The parts everyone else hand-waves.

Every rule in the engine cites its classical source. 409 yogas. 1,264 natal insight rules. 183 evaluable classical predicates. Compiled from BPHS, Raman, Jaimini, Saravali, and Phaladipika — and checked against the texts, not against a metric.

Full-fidelity Shadbala

Six strength components computed in virupas per graha — Sthana, Dig, Kala, Cheshta, Naisargika, Drik — plus per-house Bhava Bala. Hand-calculating one chart takes a practitioner hours; most software approximates or skips components.

Reproduces the fully-worked Standard Horoscope example in Raman's Graha and Bhava Balas to within ~4 virupas per graha (max |Δ| 4.07) — pinned by a test you can run.

5 dasha systems

Vimshottari to 5 recursive levels (Maha → Prana), plus the Jaimini rasi-dasa stack — Chara, Sthira, Niryana Shoola, Maheswara — which almost no software implements at all.

All five period systems addressable from the rule corpus, not just displayed.

409 yogas with cancellation

Detection is the easy half. Each detected yoga runs a 6-stage qualification (detection → eligibility → strength → purity → timing → domain) and a defeasible cancellation pass.

16 bhanga (cancellation) rules, including the 8 BPHS Ch.10 arishtabhanga that form the Balarishta defeat-graph, plus neechabhanga/kemadruma/combustion cancellations — defeat chain in the response (suppressed_by on insights, cancelled/cancellation_reason on yogas).

The Jaimini toolkit

Chara karakas, Karakamsha, Arudha lagna + Upapada, and the special lagnas (Bhava, Hora, Ghatika, Indu) — computed, predicate-addressable, and used by the rule corpus, not just displayed.

Every construct reachable from rule predicates in the DSL registry.

50 Tajika Sahams

The complete Neelkanthi saham set, implemented from the published per-saham formula definitions — including four formula corrections to a widely-circulated shorter set.

Formulas from Nilakantha's Tajik Neelkanthi, cross-checked by internal day/night-reversal relationships.

life_events 133 timed life-event rules with weighted natal/dasha/transit triggers — every trigger cited to Raman or BPHS.
ephemeris Pure-Rust clean-room — VSOP87A (planets) + ELP/MPP02 (Moon), IAU 2006 · Moon within 0.015″ of JPL Horizons at J2000 · all grahas cross-checked against an independent ephemeris across 500 charts, 0 failures.

Sources: Brihat Parashara Hora Shastra · B. V. Raman · Jaimini Upadesha Sutras · Saravali · Phaladipika · Tajik Neelkanthi — every rule carries its citation.

05Full provenance

Defend every reading you ship.

Call pramaan on any claim in a chart result, addressed by the concept URI the response already gave you. KundaliMCP traces it from the VSOP87A sky position and the ayanamsha, through chart casting, to the classical verse. No black boxes. Ever.

BPHS Ch. 36 — Gajakesari Yoga

Every claim you can see, you can interrogate — yogas, cited natal rules, domains. Same chain every time.

06Anuvada — multilingual ontology

Seven languages, without a translation vendor.

Anuvada is not a translation layer bolted on top. Every Vedic concept — yoga, dosha, nakshatra, graha — is a JSON-LD entity with axes, grammar rules, and validated surfaces in all seven languages from compile time. Add a new language without touching the engine.

JSON-LD ontology

Every yoga, graha, rashi, nakshatra, and dosha is a structured entity with axes — quality, category, domain, timing, deity. Machine-readable definitions, not a word list.

Composition rules

Each language carries its own grammar templates and morphology rules. 'Gajakesari Yoga is active during Jupiter mahadasha' conjugates correctly in Hindi — not just transliterated.

SHACL validation

Shape constraints enforce completeness at build time. A concept with a missing Tamil surface fails the build — no silent gaps, no half-translated responses.

Extensible by design

Add a new language by contributing vocabulary, composition rules, and SHACL shapes. The engine picks it up automatically at the next snapshot compile.

Adding a new language means adding vocabulary, grammar templates, and SHACL shape files to the anuvada/ directory. The engine compiles it automatically — no code changes required.

07Vertically integrated

No third party in
your critical path.

No third-party ephemeris. No vendor lock. The entire stack from raw sky coordinates to MCP response is owned and auditable. A new primitive flows sky to screen in days.
