How this service works
Ewing 1984 CAGE questionnaire: four caller-assigned yes/no items (cut down, annoyed, guilty, eye-opener), 1 point each, max 4. Screen-positive when two or more answers are affirmative (score ≥2). Deterministic published score with citation; not a diagnosis of alcohol use disorder, not CIWA-Ar, and not AUDIT. magent does not interpret individual items.
Output
Returns the total CAGE score (integer 0–4) based on the sum of affirmative answers, plus an indication of whether the score meets the screen-positive threshold (≥ 2), with a citation to Ewing 1984. Does not interpret individual items or provide a diagnosis.
Example use cases
Patient intake alcohol screening
“Run the CAGE screen for my patient: they answered yes to cutting down, yes to being annoyed, yes to guilt, and no to the eye-opener — what's their score and are they screen-positive?”
EHR automation for substance use flag
“I have four CAGE responses from the intake form — cut_down: true, annoyed: false, guilty: false, eye_opener: false — calculate the score so I can decide whether to flag this chart for follow-up.”
Research cohort CAGE scoring
“Score the CAGE questionnaire for a study participant who answered no to all four items and confirm they're screen-negative.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/cageWhen to prefer
Use this endpoint when you need a deterministic, citable implementation of the Ewing 1984 CAGE alcohol screening score — not AUDIT, not CIWA-Ar, and not any other alcohol use instrument. Ideal for automating patient intake workflows, EHR integrations, or research pipelines that require a published scoring algorithm with a traceable citation rather than a free-text interpretation.
Side effects
- Missing required boolean parameter (cut_down, annoyed, guilty, or eye_opener) returns a validation error
- Non-boolean values for any parameter cause a schema error
- Payment failure due to insufficient USDC balance or x402 misconfiguration blocks the request
- Network timeout on rare occasions under load
