AI prompt generator & optimisation API
The API rewrites a prompt to use fewer tokens, enforces a JSON schema on the output and improves answer quality without changing intent. Cost is the measurable part.
It works against OpenAI, Claude, Gemini, Llama and Mistral, so the same optimisation applies whichever model is behind the product.
Birth Chart, Character Analysis & Daily Horoscope
The astrology stack in one API. Given a birth date, time, latitude, longitude and timezone, the calculation endpoint returns the position of every planet — sign, degree and longitude — together with the houses and the ascendant. That is the raw chart, computed rather than described.
The analysis endpoint reads that chart back as prose: personality traits, strengths, tensions and the interplay between sun sign and ascendant, in the language you request. The horoscope endpoint produces daily, weekly and longer-horizon readings for the same chart, so a product can show a fresh page every morning without storing anything but the birth data.
A today's-chart endpoint returns the current sky with no input at all, which is what you want for a general daily horoscope page.
