Pricing in practice
A daily-horoscope app doing ~1,000 natal charts a month fits inside AstroWay’s free tier (10,000 credits ≈ 500 full charts) before you pay anything. Astrology-API.io’s entry tier is roughly $11 for 1K credits, so the same workload pushes you onto a paid plan quickly. AstroWay’s first paid tier starts at $5/mo.
Decision matrix
Pick AstroWay if
If you build a Human Design app, a rectification tool, or a Telegram bot on a tight budget.
Pick Astrology-API.io if
If you need the widest pool of Western endpoints and per-call cost is not critical.
How to switch
Both speak JSON over HTTPS, so moving over is mostly remapping field names and swapping the base URL to api.astroway.info. The typed TypeScript and Python SDKs remove most of the manual mapping, and the OpenAPI 3.1 spec generates a client in any language.
