asterwise-python

The official Python library for Asterwise — Vedic + Western astrology, numerology, tarot, crystals, and dreams. 117 endpoints, generated from the API's OpenAPI document so the types match what the server sends. Every position is checked against NASA JPL Horizons, median 0.046 arcseconds over 80 positions from 1950 to 2050. Compared row by row with seven other astrology APIs, every claim sourced, at asterwise.com/compare.

What you can build

122 typed SDK methods across 13 API classes covering 117 REST endpoints (5 endpoints keep a deprecated GET method next to the POST one).

What makes Asterwise different

• Classical interpretation text alongside the calculations on chart endpoints (natal chart, dasha, yogas, doshas)
• 5-level Vimshottari Dasha (Maha → Antar → Pratyantar → Sookshma → Prana) — most APIs return two
• Rajju and Vedha as hard vetoes in matchmaking — not just point scores
• HMAC-signed responses for auditability
• Panchanga as printed panchangs show it: every tithi, nakshatra, yoga and karana of the day with start and end times, the festival and vrat calendar, and muhurta search with exact ISO times
• Typed responses: every method returns a model generated from the OpenAPI document (.to_dict() gives a plain dict)
• MCP server with 104 tools for Claude and Cursor integration

bash scripts/generate.sh

Releasing: bump version in pyproject.toml (the only place it is set) → bash scripts/generate.sh (writes that version into __version__ and the User-Agent) → update CHANGELOG.md → pytest → commit → push a python-v<version> tag. The publish workflow checks the tag against pyproject.toml, runs the tests, builds, runs twine check and uploads to PyPI.
