About AstroAPI
AstroAPI was born from a simple frustration: building astrology apps meant dealing with slow, outdated, or overly complex calculation libraries. We built the API we wished existed — fast, accurate, and developer-friendly. Today, AstroAPI powers astrology applications worldwide, from indie apps to enterprise platforms.

We handle the complex astronomical calculations so you can focus on building great products. Our API delivers Swiss Ephemeris precision through simple REST endpoints, complete with professional interpretation texts and beautiful chart rendering. One API call. Instant results.
