Compatibility API for dating apps

Most dating apps show compatibility by Sun sign — and grown-up users see through that fast. You need a deeper model: a composite chart of two people, synastric aspects, midpoints.

AstroWay computes full synastry (Sun-Moon, Venus-Mars, Saturn aspects) + composite chart + Davison time-midpoint chart. One HTTP request — full compatibility analysis with a 0..100 weighted score.

• POST /v1/synastry — mutual aspects of 2 charts
• POST /v1/synastry/attraction-score — score 0..100
• POST /v1/composite — combined midpoint chart
• POST /v1/davison — Davison time-midpoint chart

// TS SDK in roadmap — native fetch today
const r = await fetch('https://api.astroway.info/v1/synastry/attraction-score', {
  method: 'POST',
  headers: { 'X-Api-Key': process.env.AW_KEY!, 'Content-Type': 'application/json' },
  body: JSON.stringify({
    partnerA: { date: '1991-08-24T16:30:00+03:00', latitude: 50.45, longitude: 30.52 },
    partnerB: { date: '1992-07-20T09:00:00+03:00', latitude: 49.84, longitude: 24.03 },
  }),
});
const { data: score } = await r.json();
console.log(score.compatibilityIndex); // 0..100
