x402
Bateman 2015 RSE (Risk Score for Exacerbations) 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 Bateman 2015 Risk Score for Exacerbations (RSE) using Table II normalized points from BMI, ACQ-5, FEV1 % predicted, daily rescue occasions, and GINA step, returning a 0–100 integer score.

How this service works
Bateman 2015 Risk Score for Exacerbations (RSE): Table II normalized points from BMI >=30 (14), ACQ-5 (<1.5=0; 1.5 to <2.5=7; >=2.5=13), FEV1 % predicted (>=90=0; 80 to <90=13; <80=20), daily rescue occasions (<2=0; 2 to <4=11; >=4=26), and GINA step (3=0; 4=27). Total 0-100. Caller-assigned; magent does not administer ACQ-5 or spirometry. Not a diagnosis, GINA step change, or inhaler order.
Output
Returns an integer RSE total (0–100) assembled from Table II normalized points across five domains: BMI flag (0 or 14), ACQ-5 band (0, 7, or 13), FEV1 % predicted band (0, 13, or 20), daily rescue occasions band (0, 11, or 26), and GINA step (0 or 27). Higher scores indicate greater exacerbation risk. The endpoint does not administer questionnaires, perform spirometry, issue diagnoses, change GINA steps, or order medications.
Example use cases
Pre-visit exacerbation risk triage
“Before my clinic tomorrow I need the Bateman 2015 RSE score for a patient on GINA step 3 with an ACQ-5 of 1.8, FEV1 at 84% predicted, 1 rescue occasion per day, and a BMI under 30 — what's their risk score?”
High-risk asthma population flagging
“Flag patients likely to exacerbate: this one is on GINA step 4, ACQ-5 of 3.1, FEV1 at 72% predicted, uses rescue inhaler 5 times daily, and has a BMI of 34 — calculate the Bateman RSE score.”
Treatment response monitoring over time
“My patient was reassessed after 3 months of step-up therapy — now GINA step 4, ACQ-5 dropped to 1.3, FEV1 improved to 91% predicted, rescue occasions down to 1 per day, BMI still 29. What's their new RSE score compared to before?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rseWhen to prefer
Use this endpoint when you need an objective, validated 0–100 numerical risk score for asthma exacerbations derived from the Bateman 2015 publication, specifically for patients on GINA steps 3 or 4. It is appropriate for automating clinical risk stratification pipelines where ACQ-5, spirometry, and other inputs have already been gathered and need to be scored per the published Table II algorithm. Prefer this over generic asthma severity tools when the Bateman 2015 derivation methodology is required for research, quality metrics, or decision support.
Side effects
- Invalid GINA step (anything other than 3 or 4) returns an invalid_gina_step error
- FEV1 % predicted outside the valid range (10–150) is rejected
- rescue_occasions_per_day outside 0–30 is rejected
- Missing any required query parameter returns a 400-level error
- ACQ-5 outside 0–6 range may be rejected or produce unexpected scoring
