## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability care-score-calculator-dupuis-2001-5e9e2d5b
```

Example prompt: Look up the Dupuis 2001 CARE score for a class 3 cardiac surgery patient who needs emergency surgery — I want the CARE label and the in-hospital mortality and morbidity percentages from the Ottawa reference population.

## When to prefer this

Use this endpoint when you need to look up the standardized Dupuis 2001 CARE score label and associated Ottawa reference population mortality/morbidity statistics for a cardiac anesthesia patient. Prefer this over EuroSCORE, Parsonnet, or Gupta MICA lookups when the clinical context is specifically the CARE classification system (class 1-5 with optional emergency suffix for classes 3-5).

## Known failure modes

- care_class 1 or 2 with emergency=true is rejected as invalid (E suffix not applicable to classes 1-2)
- care_class outside the 1-5 integer range returns a validation error
- Missing required query parameters (care_class or emergency) returns a 400 error
- Payment failure (x402) if USDC payment of $0.005 is not provided

## How this service works

Cardiac Anesthesia Risk Evaluation (CARE) score (Dupuis 2001). Caller-assigned class 1-5; emergency suffix E only for classes 3-5 (labels 3E, 4E, 5E). Returns care_label plus Dupuis 2001 Table 4 in-hospital mortality and morbidity percents from the Ottawa reference population. Not an anesthetic plan or surgical booking. magent does not examine the patient. Not Parsonnet, EuroSCORE, or Gupta MICA.

## Output

Returns the CARE label string (e.g. '3E', '4', '5E') and the corresponding Dupuis 2001 Table 4 in-hospital mortality percentage and morbidity percentage from the Ottawa reference population. Does not provide an anesthetic plan, surgical booking, or patient examination.
