AstroWay
AstroWay is a large, actively maintained astrology-calculation API — natal charts, synastry, transits, Human Design, numerology and more — built on the Swiss Ephemeris, with 700+ documented endpoints. A live GET against the real gateway, api.astroway.info/v1/health, returned a genuine version/uptime payload with no Access-Control-Allow-Origin header, and an authenticated call to /v1/chart returned a genuine 401 MISSING_API_KEY error also lacking that header, resolving cors yes -> no and reconfirming API Key auth in the same probe. A $0 free tier precedes several paid usage tiers on its own pricing page — pricingModel freemium.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
