dappgrade score — pre-transaction health/safety verdict for an onchain app, by contract address. Returns ok / caution / avoid / unknown with the coverage the verdict rests on.

Gill 2005 Simplified Motor Score (SMS) from one caller-assigned motor category: obeys (2, obeys commands), localizes (1, localizes pain), or withdrawal_or_less (0, withdrawal to pain or less). Companion to GCS, not a replacement protocol and not a triage or intubation order. magent does not examine the patient. Deterministic published score with citation.

Samuel 2002 pediatric appendicitis score from eight caller-assigned findings, ages 4-15, max 10. Cough/percussion/hopping RLQ and RIF tenderness score 2; anorexia, pyrexia, nausea/emesis, leukocytosis, neutrophilia, and migration score 1. Fever and labs are flags, not unpublished cutoffs. Not Alvarado (MANTRELS). Not a diagnosis or operating-room protocol. magent does not examine the abdomen.

Bendapudi 2017 PLASMIC: seven 1-point items (platelets <30×10^9/L, caller-assigned hemolysis, no active cancer, no solid-organ or stem-cell transplant, MCV <90 fL, INR <1.5, creatinine <2.0 mg/dL), max 7. Bands 0-4 / 5 / 6-7 are pretest groups for severe ADAMTS13 deficiency, not percents or a plasma-exchange order. magent does not assay hemolysis. Cutoffs 30, 90, 1.5, and 2.0 do not score.

Would-you-rather question generator: 120 curated dilemmas across categories including an agents-and-ai set written for AI audiences (infinite context vs zero latency), plus tech, philosophy, silly, food, adventure, and superpowers. Returns 1-5 random questions, optionally filtered by category. Clean content, no duplicates.

Calculates the great-circle distance between two GPS coordinates in kilometers, miles, and nautical miles, plus the initial compass bearing from point A to point B. For delivery routing, flight-distance estimates, and logistics agents that need an exact figure rather than an eyeballed map distance.

Distance calculator API: great-circle (haversine) distance between two coordinates in km, miles, and nautical miles, plus initial compass bearing. Deterministic and auditable — cheaper than burning reasoning tokens, zero arithmetic-hallucination risk, and the result can be cited. For logistics, travel, delivery, and geo agents. Pairs with /geocode-city for name inputs.

Unit converter API: length, mass, volume, temperature, area, speed, pressure, energy, power, and digital storage — 100+ units, exact factors. Deterministic and auditable — cheaper than burning reasoning tokens, zero arithmetic-hallucination risk, and the result can be cited.

Convert a value between units of measure: mass (g, kg, mg, lb, oz, t, st), length (m, km, cm, mm, in, ft, yd, mi), volume (l, ml, m3, gal, gal-imp, qt, pt, cup, floz, tbsp, tsp), area (m2, km2, ft2, acre, ha), and temperature (C, F, K). Units are matched case-insensitively with common aliases (kg/kilogram/kgs). Returns {value, from, to, dimension, result}. Exact factors — the ground-truth answer a CPG/ETL pipeline needs instead of an LLM approximating conversions. Cross-dimension conversions (kg→m) return 400.
