How this service works
Knight 2002 CRAFFT: six caller-assigned yes/no flags (car, relax, alone, forget, friends, trouble), 1 point each, max 6. Screen-positive when score ≥2 (optimal cutoff in Knight 2002 for any problem / any disorder / dependence). Deterministic published score with citation; not a diagnosis of a substance use disorder and not a medical device. magent does not interview the patient. Not CAGE and not CRAFFT 2.1 / 2.0 quantity questions.
Output
Returns a deterministic integer CRAFFT score (0–6) based on the sum of the six boolean inputs (1 point each), a screen-positive flag indicating whether the score meets the Knight 2002 ≥2 cutoff, and a published citation. No diagnosis is rendered; this is a scored screening instrument only.
Example use cases
Pediatric ED substance use triage
“A 16-year-old in the ED answered yes to car, relax, and friends on the CRAFFT questions, and no to alone, forget, and trouble — calculate the CRAFFT score and tell me if they're screen-positive.”
EHR intake form auto-scoring
“We collected CRAFFT responses from a patient at intake: car=yes, relax=yes, alone=yes, forget=no, friends=no, trouble=no — compute the Knight 2002 CRAFFT score and the screen-positive result so I can document it.”
Population health screening workflow
“I'm processing CRAFFT results from an adolescent wellness visit — the patient answered true to forget and trouble, and false to all others. What's the CRAFFT score and is it above the ≥2 cutoff?”

Endpoint
GEThttps://api.magentlab.com/api/calc/crafftWhen to prefer
Use this endpoint when you need a fast, deterministic, citation-backed CRAFFT score derived from the original Knight 2002 six yes/no items with the validated ≥2 screen-positive cutoff. Prefer it over general-purpose calculators when you need the specific Knight 2002 formulation (not CRAFFT 2.1 quantity additions), need a stable API with a per-call pricing model, or are integrating into an automated adolescent screening workflow where reproducibility and citation traceability matter.
Side effects
- Missing any of the six required boolean query parameters returns a validation error
- Non-boolean values for flags (e.g. strings other than true/false) cause a schema rejection
- Network or payment authentication failure (x402) prevents score retrieval
- Misinterpretation: this is the Knight 2002 six-question CRAFFT only — not CRAFFT 2.0/2.1 with quantity questions, not CAGE
