Chart Engine as an API

Arcminute-verified Jyotish natal chart computation, exposed as a hosted JSON API.

Arcminute-accurate. Automated self-check matches an independent Swiss Ephemeris path across thousands of births; the only diffs are sub-arcminute Mercury/Venus light-time convention.
Published test vectors. A deterministic sandbox response you can curl before signing up — no auth required.
Sub-second responses. Full varga + Vimshottari dasha computation on a single request.

Returns the same deterministic natal chart every time — the “hello world” of the engine. If the response ever changes, the engine drifted; it’s a self-documenting canary.
