• 198+ calculators, each with its own endpoint
• Babu maɓallin API — anonymous access, rate-limited by IP
• CORS — Access-Control-Allow-Origin: * (mai amfani da sashin mai amfani da shi)
• QFileDialog: 60 requests/hour per IP (HTTP 429 when exceeded)
• QFileDialog — only a successful (2xx) response uses one call from your monthly quota. Every 400, 401, 404, 429 and 500 costs you nothing.

Parameters, defaults and errors

Send only the fields you care about. Anything you leave out is filled with that field's published default — the same value the calculator page pre-fills, so the API and the website always return the same numbers for the same inputs. Each response lists what it filled in under defaults_applied.

Anything the API cannot resolve honestly is an error, never a zero: a misspelled parameter, a value of the wrong type, an unknown dropdown option, or a missing field that has no default (the date fields — a birth date cannot be guessed). Every 400 names the offending parameter and echoes the full field spec so a client can correct itself.
