x402
magent HIRI-MSM HIV Incidence Risk Index Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Computes the Smith 2012 seven-item HIV Incidence Risk Index for Men who have Sex with Men (HIRI-MSM), returning a total score (0–47) and a binary high-risk flag (at_or_above_10) based on caller-supplied behavioral and demographic inputs.

How this service works
Smith 2012 seven-item HIV incidence risk index for MSM. Age 18-28=8, 29-40=5, 41-48=2, >=49=0; male partners 0-5=0, 6-10=4, >=11=7; HIV-positive partners 0=0, 1=4, >=2=8; unprotected receptive anal 0=0, >=1=10; insertive anal with HIV-positive partner 0-4=0, >=5=6; poppers 3; amphetamines 5. Range 0-47; at_or_above_10 when score >=10. Caller-assigned. Not a diagnosis or PrEP order.
Output
Returns the numeric HIRI-MSM total score (integer 0–47), a boolean or flag indicating whether the score is at or above 10 (the high-risk cutoff per Smith 2012), and optionally the per-item component scores contributing to the total. This is not a diagnosis and does not constitute a PrEP prescription or clinical recommendation.
Example use cases
PrEP eligibility risk stratification
“I need to run the HIRI-MSM score for a 25-year-old patient who had 12 male sex partners in the past 6 months, 2 of whom were HIV-positive, he had unprotected receptive anal sex 5 times, insertive anal with an HIV-positive partner twice, he uses poppers but not amphetamines — tell me his total score and whether he's at or above 10.”
Research cohort risk classification
“For our study, score a 45-year-old participant using the Smith 2012 HIV incidence risk index: 4 male partners in the last 6 months, 0 HIV-positive partners, 0 unprotected receptive anal acts, 0 insertive anal acts with HIV-positive partners, no poppers, no amphetamines — what's his HIRI-MSM total?”
Clinical decision support alert
“Run the seven-item HIRI-MSM on a 38-year-old man — 7 male sex partners last 6 months, 1 HIV-positive partner, 1 unprotected receptive anal encounter, 6 insertive anal acts with an HIV-positive partner, poppers user, no amphetamines — does he hit the high-risk threshold?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/hiri_msmWhen to prefer
Use this endpoint when you need a validated, published clinical risk score (Smith 2012 HIRI-MSM) for MSM HIV incidence risk stratification, especially in digital health, PrEP decision-support, or research pipelines. Prefer this over generic risk calculators when the specific seven-item Smith 2012 instrument is required and all behavioral inputs are available from a structured intake form or EHR.
Side effects
- Missing any of the seven required query parameters returns a validation error
- Age below 18 or non-integer values rejected
- Negative integers for partner counts or act counts are invalid
- Boolean parameters passed as strings may fail parsing
- Network or payment (x402) errors return non-200 status codes
