RoxyAPI does clean computation well. Vedika adds a built-in AI query layer, three systems in one, and an open-source engine.
RoxyAPI is a genuinely good computation API. It exposes a clean, modern REST interface over Swiss-Ephemeris calculations, with strong Western-astrology coverage — natal charts, transits, synastry — and predictable JSON. If your application needs accurate planetary positions, house cusps and aspects, and you plan to build your own interpretation logic on top, RoxyAPI is a capable, no-frills choice that does exactly what it sets out to do.
Vedika solves a different problem. Instead of returning only data, Vedika can return answers. Its built-in natural-language LLM lets a user ask "Will this year be good for my career?" and get a plain-language reply grounded in the chart Vedika has already computed. It also unifies Vedic, Western and KP in one API and runs on an open-source engine you can audit. The two products overlap on raw computation but diverge sharply on everything above it.

Choose RoxyAPI if you need a focused, reliable computation API with strong Western coverage and you are comfortable writing your own interpretation and language layers. Its clean REST design and Swiss-Ephemeris foundation make it a dependable building block for chart-rendering and data-driven features.
Choose Vedika if you want answers rather than raw data, need Vedic, Western and KP in one integration, want an ephemeris you can independently audit (open-source XALEN, validated against JPL DE440), or are building an AI agent that should call astrology natively through an MCP server. The free sandbox lets you evaluate every endpoint — including the AI query path — before committing, and the entry plan is $12/month.
