# Magent Myxedema Coma Score (Popoveniuc 2014)

> Magent Myxedema Coma Score (Popoveniuc 2014) 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).

Calculates the Popoveniuc 2014 myxedema coma diagnostic score from caller-supplied clinical bands across thermoregulatory, CNS, GI, cardiovascular, and metabolic domains (max 230 points).

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 magent-myxedema-coma-score-popoveniuc-2014-1043ff73
```

Example prompt: Score this patient for myxedema coma using the Popoveniuc 2014 criteria: temperature band is thermoregulatory 20 points (hypothermia present), CNS is obtunded, GI effects are absent, there was a precipitating event, bradycardia is in the 40-to-49 range, no other EKG changes, no effusion, no pulmonary edema, no cardiomegaly, hypotension is present, hyponatremia is true, hypoglycemia is false, hypoxemia is true, hypercarbia is false, and GFR is decreased.

## When to prefer this

Use this endpoint when you need a structured, reproducible computation of the Popoveniuc 2014 myxedema coma score and all required clinical bands and flags have already been determined by a clinician or upstream system. It is the right choice for clinical decision-support pipelines in emergency, ICU, or endocrine settings where the scoring arithmetic needs to be automated. Do not use it to measure vital signs, interpret labs, or diagnose — those inputs must come from the caller.

## Known failure modes

- Missing required query parameters returns a validation error
- Invalid enum values for banded fields (e.g. unrecognized bradycardia band) return an error
- Boolean fields supplied as non-boolean strings may cause schema rejection
- Payment failure (x402) if USDC balance is insufficient — call not processed
- Score returned is only as accurate as caller-supplied inputs; no measurement or validation of clinical values is performed

## How this service works

Popoveniuc 2014 myxedema coma points from caller-assigned bands: thermoregulatory 0/10/20; CNS 0/10/15/20/30; GI 0/5/15/20; precipitant 10; bradycardia 0/10/20/30 plus other EKG 10, effusion 10, pulmonary edema 15, cardiomegaly 15, hypotension 20; five metabolic flags 10 each. Max 230. ≥60 potentially diagnostic; 45–59 at risk. Not a diagnosis or thyroid-hormone order. magent does not measure temperature, GCS, or labs.

## Output

Returns a numeric myxedema coma score (0–230) computed from the caller-supplied clinical bands and boolean flags. The score is interpreted as: ≥60 potentially diagnostic for myxedema coma, 45–59 at risk. The endpoint does not perform any measurement, lab interpretation, or imaging analysis — all inputs must be pre-assigned by the caller. The result is a decision-support value only and does not constitute a diagnosis.
