Proof, with the method beside it
What we measured, how to rerun it, and what it does not show. The evaluation of how AI systems answer astrology questions, the Vedika Bench, is coming soon and has no results yet.

Coverage
Three systems, kept separate
Each system is computed on its own, so a value from one never leaks into another. The full endpoint list is in the API reference.
Show the systems table
| System | Zodiac | What it covers |
|---|---|---|
| Vedic | Sidereal | Divisional charts from D1 to D60, several dasha systems, dosha analysis, Panchang and Muhurta. |
| Western | Tropical | Natal and transit charts, aspects, house systems and sign placements. |
| KP | Krishnamurti Paddhati | Sub-lord and cuspal analysis, significators, ruling planets and horary (Prashna). |
The endpoint catalogue also covers numerology, tarot, matrimony, Chinese astrology, Human Design, I Ching, daily content and more.

Planet positions against NASA JPL DE440
XALEN Ephemeris is our own engine for planet positions, house cusps and divisional charts. The table is its measured agreement with NASA's DE440 reference ephemeris over a 1900 to 2050 grid of 3,653 epochs per body, in arcseconds of ecliptic longitude.

| Body | Mean (″) | RMS (″) | Max (″) |
|---|---|---|---|
| Sun | 0.08 | 0.10 | 0.19 |
| Mercury | 0.08 | 0.10 | 0.26 |
| Venus | 0.09 | 0.11 | 0.40 |

Rerun it yourself
The benchmark source is in the public xalen-ephemeris repository, which also carries the instructions to run it. Start by fetching NASA's public DE440 kernel:
curl -L -o /tmp/de440s.bsp https://naif.jpl.nasa.gov/pub/naif/generic_kernels/spk/planets/de440s.bspWhat this does not show: it compares positions only, in ecliptic longitude. It says nothing about the quality of any interpretation, and it does not test houses, dashas or the AI answers.
Interpretation
Interpretation is grounded in classical texts
Astronomy is computed. Interpretation cites the sources below, and where a source is silent the answer says so.
- BPHS Brihat Parashara Hora Shastra
- Phaladeepika Mantreswara
- Saravali Kalyana Varma
- Jaimini Jaimini Sutras
Performance
Speed and service status
~50 ms median server time
Measured on calculation endpoints in Oct 2026. AI answers take longer. Live service status is published at vedika.io/status. Vedika runs on multi-region cloud infrastructure and routes each request automatically. Customers agree any data-residency needs at signup, as part of enterprise terms. Uptime and support terms for enterprise plans are agreed in a signed order form.
