Ideal body weight and clinical body-metric maths as an API, computed locally and deterministically. The ideal endpoint computes ideal body weight from height and sex by the four standard formulas — Devine (the clinical standard for drug dosing), Robinson, Miller and Hamwi — each adding a per-inch increment for every inch above 5 ft, plus their average; a 5 ft 10 in (178 cm) man comes out at 73.0 kg by Devine. The adjusted endpoint computes the adjusted body weight used to dose drugs in overweight patients, ABW = IBW + 0.4·(actual − IBW), from height, sex and actual weight. The bsa endpoint computes body surface area — central to chemotherapy and cardiac-index dosing — by the Mosteller (√(height·weight/3600)), Du Bois and Haycock formulas, so a 180 cm, 80 kg adult is about 2.0 m². Height is accepted in centimetres or inches and weight in kilograms. Everything is computed locally and deterministically, so it is instant and private. Ideal for digital-health, EHR, pharmacy, clinical-decision-support, telemedicine and medical-education app developers, dosing and body-metric tools, and health software. These are clinical estimation formulas, not a substitute for professional medical judgement. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is ideal/adjusted weight and body surface area; for body-mass index use a BMI API.

Standard clinical and nursing calculators as an API — the everyday medical maths, computed locally. The bsa endpoint computes body surface area from weight and height by the Mosteller, Du Bois and Haycock formulas (used for chemotherapy and drug dosing). The egfr endpoint estimates kidney function from serum creatinine, age and sex using the race-free CKD-EPI 2021 equation, and the Cockcroft-Gault creatinine clearance when a weight is given (creatinine in mg/dL or µmol/L). The drip-rate endpoint computes an IV infusion's drops per minute and millilitres per hour from the volume, time and drop factor. The gcs endpoint scores the Glasgow Coma Scale from its eye, verbal and motor components and gives the severity band. Everything is computed locally and deterministically, so it is instant and private. INFORMATIONAL ONLY — not medical advice; always verify with clinical judgement and approved tools. Ideal for healthcare and nursing apps, clinical decision-support prototypes, medical education, and EHR tooling. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This is clinical maths; for drug reference data use a drug API and for BMI, BMR and calories use a health-calculator API.
