What you can compute

One generic endpoint exposes every calculator in the registry by name — natal, time-based and symbolic techniques. No hand-maintained endpoint list.

🕉️Vedic (sidereal)

Yogas, doshas, dashas, divisional charts, nakshatras, KP, Jaimini — from classical catalogs with citations.

Western & Hellenistic

Aspects, dignities, midpoints, fixed stars, Arabic parts, timelords, predictive timelines.

🃏Symbolic systems

Tarot and I Ching engines driven by declarative catalogs.

🔢Numerology

Life-path, expression and soul numbers, personal-year forecasts.

🌍Mundane & remedies

Country profiles, Lal Kitab remedies, heliacal phenomena.

🪐Ephemeris core

Swiss Ephemeris positions, houses, ingresses, eclipses and stations.

Two ways to integrate

REST HTTP for any stack

Send parameters, get structured JSON back. Universal and understood by any developer.

POST /v1/calc/western.core.natal_chart
X-API-Key: acx_…
{ "birth_date": "1990-06-15", "birth_time": "14:30",
  "latitude": 55.75, "longitude": 37.62,
  "timezone_offset": "+03:00" }

MCP Native for AI agents

Model Context Protocol lets AI assistants like Claude and ChatGPT discover and call our tools directly inside a conversation — no glue code.

POST /v1/mcp # JSON-RPC 2.0
{ "method": "tools/list" }
{ "method": "tools/call", … }

Connect AstroCodex to your own AI

  1. 1Subscribe to a plan that includes MCP and issue an API key in your profile.
  2. 2Add the AstroCodex MCP connector to your AI client (Claude, ChatGPT or any MCP-aware agent) with your key.
  3. 3Ask in plain language — "build my chart and analyze Venus". The agent calls our tools and interprets the result.

Indicative pricing — final tiers are confirmed at launch. Computation never leaves our servers; agents receive only the result.

Localized results

Catalog engines return every name in all four languages at once — name_en, name_ru, name_es, name_hi — and accept a "lang" parameter in the request body ("en", "ru", "es" or "hi"; default "en") for a localized primary name. The platform UI ships in 30+ languages.
