# ASA Physical Status Classification

> ASA Physical Status Classification 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).

Returns the official ASA Physical Status class label and its published definition for a caller-assigned class (1–6) with optional emergency suffix E

## Facts

- Endpoint: GET https://api.magentlab.com/api/calc/asa_physical_status
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 asa-physical-status-classification-8e279ecc
```

Example prompt: Look up the official ASA Physical Status class label and definition for a class 3 patient undergoing emergency surgery — so the emergency suffix E should be appended.

## When to prefer this

Use this endpoint when you need the canonical, standards-body-published ASA Physical Status label and definition for anesthesia documentation, preoperative records, or clinical data encoding. Prefer it over free-text generation when accuracy to the official ASA 2014/2020 wording is required. Not a substitute for Gupta MICA risk scoring, Mallampati airway assessment, or any anesthetic planning tool.

## Known failure modes

- asa_class outside 1–6 range returns a validation error
- missing required emergency boolean returns a 400/422 error
- payment failure (x402) blocks the call entirely
- network timeout results in no response

## How this service works

ASA Physical Status Classification System (ASA House of Delegates 2014, last amended 2020). Caller-assigned class 1-6 plus optional emergency suffix E. Returns asa_label (e.g. 1 or 2E) and the published class definition. Classification alone does not predict perioperative risk. Not an anesthetic plan, not Gupta MICA, not Mallampati. magent does not examine the patient.

## Output

Returns an asa_label string combining the numeric class and optional E suffix (e.g. '3E'), plus the official published ASA Physical Status class definition text as adopted by the ASA House of Delegates (2014, amended 2020).
