Draconic Chart API
Re-anchor the whole zodiac to the Moon's North Node. Slide 0° Aries onto the natal North Node and every planet is re-read in nodal — 'draconic' — longitude. Pass a birth chart, get planets, houses, and aspects expressed in the draconic frame. Swiss Ephemeris precision, JSON out.
Draconic Chart API
The draconic endpoint computes the standard tropical chart from the birth data, then rotates the entire zodiac so that the Moon's North Node sits at 0° Aries. Every planetary longitude is shifted by that same amount — subtract the node's tropical position from each — re-expressing the whole chart in nodal, or draconic, coordinates while preserving all the relative angular relationships between bodies. The response returns the draconic planets with their new signs and house placements, the house cusps in the rotated frame, and the full aspect grid with applying and separating flags and exact orbs. Because the rotation is rigid, the aspects between planets stay intact; what changes is which signs and degrees they occupy. The draconic chart is traditionally read as a soul-level or karmic overlay, the inner pattern beneath the tropical personality chart.

When to use it
Use the draconic chart when you want the karmic or soul-purpose layer that astrologers read beneath the ordinary natal chart — a 'soul chart' feature, a depth-astrology report, or an AI narrative that contrasts the tropical self with the draconic essence. It is most revealing when compared against the tropical chart of the same person, or laid over a partner's chart in draconic synastry to surface soul-level contact. Because the transformation is a clean rotation, you can compute the tropical natal once and request the draconic version to place the two side by side. Reach for it in interpretive, reflective contexts rather than event-timing ones — it speaks to underlying pattern and intent, not to dates.
Notes
The rotation is anchored to the Moon's North Node, placing it at 0° Aries; all bodies shift by the node's tropical longitude, so inter-planet aspects are preserved and only sign and degree placements change. Read it as a karmic overlay to the tropical chart, not a replacement. Houses follow your chosen system in the rotated frame; tropical-derived and Swiss Ephemeris throughout.
