x402
HOPE Score Calculator (Pasquier 2018) for Hypothermic Cardiac Arrest 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 HOPE survival probability score for patients with hypothermic cardiac arrest undergoing ECLS, returning logit, estimated survival percent, and HOPE ≥10% flag per Pasquier 2018 Table 2.

How this service works
Pasquier 2018 HOPE survival probability after ECLS for hypothermic cardiac arrest from sex (published male coefficient, not race), asphyxia, age, potassium, CPR duration, and temperature. Returns logit, estimated_survival_percent from the unrounded logit, and Table 2 HOPE >= 10% flag. Not an ECLS or rewarming order. magent does not cannulate.
Output
Returns a JSON object containing the raw logit value derived from the Pasquier 2018 model, the estimated survival probability as a percentage (computed from the unrounded logit), and a boolean flag indicating whether HOPE ≥10% (Table 2 threshold). Does not issue clinical orders or cannulation instructions.
Example use cases
ECLS candidacy triage in the ED
“I have a 35-year-old female hypothermic arrest patient — non-asphyxia mechanism, core temp 19°C, potassium 5.8 mmol/L, and she's been on CPR for 60 minutes. Run the HOPE score and tell me if her estimated survival is at or above 10%.”
Post-resuscitation outcome documentation
“For our case report, calculate the Pasquier 2018 HOPE logit and survival probability for a 58-year-old male, asphyxia present (head submerged with arrest at extrication), temperature 22°C, potassium 8.1 mmol/L, CPR for 90 minutes.”
Comparing scenarios with different potassium levels
“Run the HOPE score twice for a 50-year-old male, no asphyxia, 30°C core temp, 30 minutes CPR — first with potassium 4.0 mmol/L and then with potassium 9.5 mmol/L, so I can see how potassium shifts the estimated survival percent.”

Endpoint
GEThttps://api.magentlab.com/api/calc/hopeWhen to prefer
Use this endpoint when you need to apply the published Pasquier 2018 HOPE model exactly — including the correct sex coefficient, log2 transformations for CPR duration and potassium, and both linear and squared temperature terms — and need the raw logit alongside the survival percent and HOPE ≥10% flag. Prefer this over manual calculation or generic survival models when working with accidental hypothermic cardiac arrest patients being evaluated for ECLS candidacy.
Side effects
- Missing required parameters (age, sex, asphyxia, cpr_duration_min, potassium_mmol_l, temperature_c) returns 400 validation error
- cpr_duration_min ≤ 0 is invalid (log2 undefined), returns error
- potassium_mmol_l ≤ 0 is invalid, returns error
- temperature_c outside 10-37°C range may produce out-of-range or error response
- Age outside 0-100 may be rejected
- Invalid sex enum value (not 'male' or 'female') returns validation error
- Payment failure (x402 unpaid) returns 402
