# CIRS-G Score Calculator (Miller 1992)

> CIRS-G Score Calculator (Miller 1992) 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 Cumulative Illness Rating Scale for Geriatrics (CIRS-G) total score and count of severely-rated categories from 14 caller-assigned organ-system severity integers (0–4).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 cirs-g-score-calculator-miller-1992-6e1bacdd
```

Example prompt: Calculate the CIRS-G score for a patient with heart rated 2, vascular 1, hematopoietic 0, respiratory 3, EENT 1, upper GI 0, lower GI 2, liver 0, renal 2, genitourinary 1, musculoskeletal 3, neurologic 2, endocrine-metabolic 1, and psychiatric 0 — give me the total score and how many categories are rated 3 or above.

## When to prefer this

Use this endpoint when you need to compute the validated Miller 1992 CIRS-G comorbidity burden score from 14 organ-system severity ratings. Prefer this over Charlson Comorbidity Index endpoints when the scoring instrument specifically required is CIRS-G (e.g., geriatric oncology studies, frailty research, or clinical contexts that use the 14-system organ-severity framework). This is a pure arithmetic computation — not a diagnosis or clinical recommendation.

## Known failure modes

- Missing any of the 14 required organ-system query parameters returns a validation error
- Any parameter value outside the integer range 0–4 is rejected
- Non-integer values for organ-system fields are rejected
- Network or payment (x402) failure returns an error without a score

## How this service works

Miller 1992 CIRS-G from 14 caller-assigned organ-system integers 0-4 (heart, vascular, hematopoietic, respiratory, EENT, upper GI, lower GI, liver, renal, genitourinary, musculoskeletal, neurologic, endocrine-metabolic, psychiatric). magent does not examine the patient. Total 0-56 plus count of categories rated ≥3. No total-score class. Not Charlson. Not a diagnosis.

## Output

Returns the CIRS-G total score (sum of all 14 organ-system ratings, range 0–56) and the count of categories assigned a severity of 3 or 4 (indicating severe or extremely severe conditions). No overall severity class is returned; this is purely arithmetic aggregation of caller-supplied values.
