“Wired up the natal-chart endpoint in an afternoon. The synastry scoring is genuinely good — my compatibility app shipped in a weekend instead of three months.”
“The MCP server alone sold me. I pull horoscope data straight into Claude for my newsletter and it just works. Credit pricing is transparent — no surprise bills.”
“I needed moon-phase + numerology for a wellness tracker. One API key, typed responses, decent docs. Exactly what a solo dev wants instead of stitching three half-baked services.”
Free tier includes 100 requests/month. No credit card required.
