svgRenderUrl

string<uri>

Bearer link to the rendered Visual Chart SVG. Carries a signed render token (HMAC-SHA256) encoding only center/gate activations — no birth data, no account id. Non-expiring; renders the caller's active template, or the default theme when none is set.

Example:

"https://render.appdebock.nl/default.svg?t=eyJ..."

Generate a chart with a rendered image from coordinatesGenerates a complete Human Design chart from birth date, time, and geographic coordinates, and returns a `svgRenderUrl` for the rendered Visual Chart image alongside the chart data. No geocoding key required — timezone is resolved from lat/lng directly. Requires the "advanced" access tier.
