# WIfI Clinical Staging Calculator (Mills 2014)

> WIfI Clinical Staging Calculator (Mills 2014) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Computes and labels the Mills 2014 WIfI (Wound, Ischemia, foot Infection) clinical stage from three caller-assigned integer grades (0–3 each) and returns a formatted W#-I#-fI# label.

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 wifi-clinical-staging-calculator-mills-2014-8e8e2a87
```

Example prompt: Calculate the WIfI stage for my patient: wound grade 2 (deeper ulcer with exposed bone), ischemia grade 1 (mild), and foot infection grade 0 (no infection) — give me the W#-I#-fI# label.

## When to prefer this

Use this endpoint when you need to encode caller-assigned Mills 2014 WIfI grades into the standardized W#-I#-fI# label for vascular surgery documentation, EHR entry, or clinical staging workflows. This is not PEDIS scoring and does not interpret ABI or wound images — the caller must supply all three grades from clinical assessment. Prefer this over manual label construction to ensure correct formatting and consistent grade encoding.

## Known failure modes

- Grade values outside 0–3 integer range will result in a validation error
- Missing any of the three required query parameters (wound, ischemia, foot_infection) returns a 400 error
- Non-integer values for grade parameters cause schema validation failure
- Payment not included or insufficient USDC results in 402 Payment Required

## How this service works

Mills 2014 SVS WIfI: three independent caller-assigned grades, not a summed total. Wound 0-3 (no ulcer; small shallow distal ulcer; deeper ulcer or digital gangrene; extensive ulcer or gangrene). Ischemia 0-3 (none; mild; moderate; severe). Foot infection 0-3 (none; skin/subcutaneous; deeper without SIRS; with SIRS). Label like W0-I0-fI0. Caller assigns grades. Not a medical device, not PEDIS, and not an amputation or revascularization order; magent does not inspect wounds or measure ABI.

## Output

Returns a formatted WIfI label in W#-I#-fI# notation (e.g. W2-I1-fI0) representing the three independently assigned Mills 2014 grades for wound, ischemia, and foot infection. The response encodes the caller-supplied grades into the standardized SVS WIfI clinical staging format without performing any clinical inspection, measurement, or diagnosis.
