- For births above the polar circle, it switches from Placidus to Porphyry and indicates that change in the response.
Field notes
The documented workflow sends UTC moments and geographic coordinates to a single endpoint and returns positions in JSON, with examples in three programming languages. The page says requests can include up to ten charts and lists four house systems; for locations above the polar circle, it says the service substitutes Porphyry for Placidus and reports that choice. Its benchmark section reports comparisons on 565 charts, but those figures are presented by the service itself.
