x402
PRECISE-DAPT Bleeding Risk Score Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Computes the Costa 2017 PRECISE-DAPT integer score (0–100) for predicting bleeding risk after coronary stenting, flagging high bleeding risk when score ≥25

How this service works
Costa 2017 PRECISE-DAPT nomogram after coronary stenting. Truncated linear points: age (0 at <=50, 19 at >=90), caller CrCl mL/min (0 at >=100, 25 at 0), hemoglobin g/dL (0 at >=12, 15 at <=10), WBC x10^3/uL (0 at <=5, 15 at >=20), plus 26 for previous spontaneous bleeding. Integer score 0-100; high_bleeding_risk if score >=25. Not a DAPT duration order. magent does not compute Cockcroft-Gault.
Output
Returns a PRECISE-DAPT integer score from 0 to 100 computed from the truncated linear nomogram (age, CrCl, hemoglobin, WBC, prior spontaneous bleeding), along with a high_bleeding_risk boolean flag that is true when the score is 25 or above. Does not provide DAPT duration recommendations.
Example use cases
Post-PCI bleeding risk stratification
“My patient just had a coronary stent placed — they're 67 years old, CrCl is 58 mL/min, hemoglobin is 11.2 g/dL, WBC is 9.0 ×10³/µL, and they've had a spontaneous bleed before. What's their PRECISE-DAPT score and are they high bleeding risk?”
DAPT decision support for cardiologist
“I need to assess bleeding risk before deciding on DAPT duration. Patient is 81 years old, CrCl 32 mL/min, hemoglobin 10.1 g/dL, WBC 12.5 ×10³/µL, no prior spontaneous bleeding. Run the Costa 2017 PRECISE-DAPT calculator and give me the score.”
Automated pre-discharge cardiology checklist
“For the discharge summary workflow, calculate the PRECISE-DAPT score for this post-stenting patient: age 55, creatinine clearance 95 mL/min, hemoglobin 13.0 g/dL, WBC 6.8 ×10³/µL, previous spontaneous bleeding false. Is this patient at high bleeding risk?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/precise_daptWhen to prefer
Use this endpoint when an AI agent or clinical workflow needs a validated, point-of-care bleeding risk integer score specifically for post-coronary-stenting patients following the Costa 2017 PRECISE-DAPT nomogram. Prefer this over generic risk calculators when the clinical question is bleeding risk (not ischemic risk) in a DAPT context. Note: the caller must supply pre-computed CrCl (Cockcroft-Gault) — use a separate renal function endpoint if CrCl is not already available. Not intended for DAPT duration ordering or as a standalone clinical decision.
Side effects
- Missing required query parameters (age, crcl_ml_min, hemoglobin_g_dl, wbc_k_ul, previous_spontaneous_bleeding) returns a 400-level error
- Out-of-range values (e.g. age <18 or >120, WBC outside 0.1–100) may be rejected or clamped
- Caller must pre-compute Cockcroft-Gault CrCl — this endpoint does not derive CrCl from serum creatinine
- Payment failure or missing x402 payment header returns 402 Payment Required
- Non-GET HTTP method returns method-not-allowed error
