x402
AUDIT-C Alcohol Screening Score Calculator (Bush 1998) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Computes the AUDIT-C total score (0–12) from three caller-assigned item scores and returns binary flags for the Bush 1998 cutoffs of ≥3 and ≥4.

How this service works
Bush 1998 AUDIT-C from three caller-assigned integers 0-4 (frequency, typical drinks, binge frequency); magent does not map drink-count categories. Total 0-12. This paper reported ≥3 as sensitive and ≥4 as more specific for heavy drinking / active abuse or dependence in VA outpatients (mostly men). Returns screen_ge_3 and screen_ge_4. Not later sex-specific VA primary-care cutoffs, not the full 10-item AUDIT, and not CIWA-Ar. Not a diagnosis.
Output
Returns the AUDIT-C total score (sum of the three item scores, range 0–12) along with two boolean flags: screen_ge_3 (true if total ≥ 3, the more sensitive Bush 1998 cutoff for heavy drinking) and screen_ge_4 (true if total ≥ 4, the more specific cutoff for active alcohol abuse or dependence in VA outpatients).
Example use cases
Primary care alcohol risk flagging
“I have a VA outpatient who answered the first three AUDIT questions: frequency score 3, typical drinks score 2, binge frequency score 2 — can you compute their AUDIT-C total and tell me if they screen positive at the ≥3 or ≥4 threshold?”
EHR workflow clinical decision support
“We're building an alert for our EHR: a patient has AUDIT item 1 = 1, item 2 = 2, item 3 = 0 — calculate the Bush 1998 AUDIT-C score and return the screen_ge_3 and screen_ge_4 flags.”
Population health screening audit
“For a quality review, I need to score 50 patients — starting with one who has drinking frequency 4, typical drinks 4, binge frequency 3. Give me their AUDIT-C total and whether they cross the ≥3 and ≥4 cutoffs.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/audit_cWhen to prefer
Choose this endpoint when you need a fast, deterministic computation of the Bush 1998 three-item AUDIT-C score from pre-assigned integer item scores and want the standard ≥3/≥4 VA outpatient cutoffs. Do not use it if you need the full 10-item AUDIT, sex-specific primary care cutoffs, CIWA-Ar severity scoring, or if you need the endpoint to map free-text drink-count categories to scores — the caller must supply pre-scored integers.
Side effects
- Integer values outside 0–4 may cause a validation error or unexpected results
- Missing required query parameters (frequency, typical_drinks, binge_frequency) will return an error
- Non-integer inputs will fail schema validation
- This endpoint does not apply sex-specific cutoffs or full 10-item AUDIT logic — misuse if those are intended
