# MACOCHA Score Calculator

> MACOCHA 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 2026-09-14).

Computes the De Jong 2013 MACOCHA score (0–12) for predicting difficult intubation risk from seven caller-assigned clinical flags

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 macocha-score-calculator-675ae876
```

Example prompt: Calculate the MACOCHA score for a patient who has Mallampati III, known obstructive sleep apnea, no reduced cervical mobility, no limited mouth opening, is in a coma, no severe hypoxemia, and the operator is not an anesthesiologist.

## When to prefer this

Use this endpoint when you have all seven MACOCHA clinical flags pre-assessed by a clinician and need a validated, evidence-based numeric score for difficult intubation prediction per De Jong 2013; prefer it over manual calculation to avoid arithmetic errors and to get a structured high_risk classification automatically. Not suitable if raw clinical measurements (GCS, SpO2 values, Mallampati class integer) need to be interpreted first — the caller must pre-classify those flags.

## Known failure modes

- Missing any of the seven required boolean query parameters returns a 400 validation error
- Passing non-boolean values (e.g. strings or integers) for flag fields causes schema rejection
- Payment failure or missing x402 payment header results in 402 Payment Required
- Network timeout if the API host is unreachable

## How this service works

De Jong 2013 MACOCHA from seven caller-assigned flags: Mallampati III or IV (5), OSA (2), reduced cervical mobility (1), mouth opening <3 cm (1), coma (1), SpO2 <80% (1), non-anesthesiologist (1). Total 0-12 (0 easy, 12 very difficult); high_risk at >=3. Not an intubation order. magent does not examine the airway, compute GCS, or measure SpO2.

## Output

Returns a MACOCHA total score from 0 to 12, a boolean high_risk flag (true when score >= 3), and a textual difficulty interpretation; higher scores indicate greater predicted difficulty of intubation.
