# magent PEDIS Diabetic Foot Ulcer Classifier

> magent PEDIS Diabetic Foot Ulcer Classifier 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 IWGDF PEDIS classification for a diabetic foot ulcer from five caller-assigned integer grades (Perfusion, Extent, Depth, Infection, Sensation)

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-pedis-diabetic-foot-ulcer-classifier-47222a88
```

Example prompt: Using the PEDIS system, classify a diabetic foot ulcer where the patient has PAD without critical limb ischemia (perfusion 2), the wound is about 2 cm² (extent 2), it extends to the fascia (depth 2), there's a skin-only infection (infection 2), and protective sensation is lost (sensation 2).

## When to prefer this

Use this endpoint when you need to programmatically generate or validate a Schaper 2004 IWGDF PEDIS classification label from five pre-assigned clinical grades. It is ideal for clinical documentation pipelines, research cohort encoding, or any workflow where a clinician has already assessed the five PEDIS domains and needs a formatted, standards-aligned label. It does not perform clinical assessment — all grades must be assigned by the caller.

## Known failure modes

- Missing required grade parameter returns validation error
- Out-of-range integer (e.g. perfusion=4, sensation=3) returns error
- Non-integer values for grade parameters cause schema rejection
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Schaper 2004 IWGDF PEDIS: five independent grades, not a summed total. Perfusion 1-3 (no PAD; PAD without CLI; CLI). Extent 1-3 (<1; 1-3; >3 cm2). Depth 1-3 (superficial; fascia/muscle/tendon; bone/joint). Infection 1-4 (none; skin; deeper without SIRS; with SIRS). Sensation 1-2 (protective sensation present or lost). Label like 1-1-1-1-1. Caller assigns grades. Not a medical device or IWGDF treatment; magent does not measure the ulcer, diagnose PAD, or probe bone.

## Output

Returns a formatted PEDIS label string (e.g. '2-2-2-2-2') representing the five independent grades — Perfusion, Extent, Depth, Infection, Sensation — as defined in the Schaper 2004 IWGDF PEDIS classification system, along with the individual grade values.
