Tools
| Tool | Description | Behaviour |
|---|---|---|
| best_cities | The catalogue of major cities ranked for one chart, overall or by chosen life spheres, worldwide or in one region. (API Pro) | Read-only |
| best_days | Every day of a window of up to 62 days scored for one activity (general, business, romance, health, creative, travel, home, clarity): helping and hindering transits, Moon phase and sign, void of course. The five best days first. (API Pro) | Read-only |
| daily_transits | The calculated day: the sky at noon UTC, the Moon's phase, the sky events of the coming week and, with birth data, every transit to the natal chart with its orb. No generated text. | Read-only |
| location_score | One place against one chart: the relocated angles, the planets on them with orbs, a score for each life sphere and an overall score. (API Pro) | Read-only |
| natal_chart | A natal chart from birth data. "part" picks what to return: full (everything: bodies with sign, degree, speed, retrograde flag and house; the angles; twelve Placidus cusps; aspects with orbs; element and quality balance; fixed-star contacts), short (Sun, Moon and Ascendant, each body's sign, retrograde bodies, dominant element and quality), or one part: planets, angles, houses, aspects, elements, fixed-stars. Full by default. | Read-only |
| sky | Planetary positions, Moon phase and the coming week's sky events for a date (?date=YYYY-MM-DD, today by default). | Read-only |
| solar_return | The solar return chart for a year, cast for the birth place or another location. (API Pro) | Read-only |
| synastry | Two charts compared: inter-chart aspects with orbs, house overlays both ways and a score per life sphere. (API Pro) | Read-only |
| transits | Every transit event in a window of up to 92 days: exact transit-to-natal aspects by date, sign ingresses and stations. (API Pro) | Read-only |
| usage | Your plan, today's count and when the pool refills. Costs nothing. | Read-only |
