How this service works
Stewart 1999 MIDAS from five caller-assigned 3-month day counts: missed paid work/school, work/school ≥50% reduced, missed household work, household ≥50% reduced, missed family/social/leisure. Each 0-90; total 0-450. magent does not include questions A or B and does not assign or de-duplicate days. Grades I 0-5 little/minimal, II 6-10 mild, III 11-20 moderate, IV ≥21 severe. Not a migraine diagnosis, not a triptan/prophylaxis order, not GAD-7 or PHQ-9.
Output
Returns the MIDAS total score (integer, 0–450, sum of the five input day counts) and the corresponding disability grade: Grade I (0–5, little/minimal), Grade II (6–10, mild), Grade III (11–20, moderate), or Grade IV (≥21, severe). Does not diagnose migraine or recommend treatment.
Example use cases
Migraine clinic intake assessment
“My patient with migraines reported the following over the last 3 months: 12 days of missed work, 6 days where work productivity was cut in half, 4 days of missed household work, 3 days of reduced household productivity, and 5 days of missed social or leisure activities. What is their MIDAS score and grade?”
Telehealth headache triage
“A patient on our telehealth platform said they missed 0 days of work but had 3 days of reduced work output, missed 1 day of housework, had 2 days of reduced household productivity, and missed 4 days of social activities over the past 3 months. Can you compute their MIDAS total and tell me whether that's grade I, II, III, or IV?”
Research cohort disability grading
“For a migraine research participant I have these 3-month counts: 21 missed work days, 10 reduced work days, 18 missed household days, 12 reduced household days, and 9 missed social days. What's their MIDAS total score and which disability grade does that put them in?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/midasWhen to prefer
Use this endpoint when you need a standardized, validated MIDAS disability score and grade from five pre-collected 3-month activity-impact day counts. Prefer it over manual calculation to avoid arithmetic errors, and when you need a structured grade label (I–IV) for clinical documentation, research, or triage workflows. Not appropriate for diagnosing migraine, prescribing triptans or prophylaxis, or computing psychiatric screening scores like GAD-7 or PHQ-9.
Side effects
- Missing any of the five required query parameters returns a validation error
- Values outside the 0–90 integer range per item may be rejected or produce unexpected scores
- Double-counted days between missed and reduced categories are not de-duplicated by the API — caller must handle this
- Non-integer inputs will fail schema validation
- Payment failure (x402) if USDC balance is insufficient
