# PAINAD Score Calculator (Warden 2003)

> PAINAD Score Calculator (Warden 2003) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

Computes the Pain Assessment in Advanced Dementia (PAINAD) score by summing five caller-assigned behavioral items, each rated 0–2, yielding a total 0–10.

## Facts

- Price: $0.005/call
- Payment: x402

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 painad-score-calculator-warden-2003-1d2cf400
```

Example prompt: Calculate the PAINAD score for my patient: breathing is 1 (occasional labored breathing), negative vocalization is 2 (repeated troubled calling out), facial expression is 2 (grimacing), body language is 1 (tense), and consolability is 1 (distracted by voice).

## When to prefer this

Use this endpoint when you need a fast, reliable arithmetic implementation of the Warden 2003 PAINAD scale for patients who cannot self-report pain (e.g., advanced dementia), and you have already assigned the five behavioral item scores yourself. Prefer this over manual calculation to avoid arithmetic errors in clinical documentation workflows. Do not use this endpoint if you need clinical interpretation, automatic patient observation, pain diagnosis, or intensity cutoff thresholds beyond what the original 2003 Warden paper specifies.

## Known failure modes

- Missing required query parameter returns an error (all five items are required)
- Integer values outside 0–2 for any item may be rejected or produce unexpected results
- API does not validate clinical accuracy of caller-assigned item scores — garbage in, garbage out
- Network or payment failure (x402 micropayment not fulfilled) returns a 402 or connection error

## How this service works

Warden 2003 PAINAD from five caller-assigned 0-2 items (breathing, negative_vocalization, facial_expression, body_language, consolability) using that paper's 0/1/2 descriptors. magent sums only (max 10) and does not observe the patient. No later intensity cutoffs. Not a pain diagnosis or analgesic order.

## Output

Returns the summed PAINAD total score as an integer from 0 to 10, reflecting the arithmetic sum of the five caller-supplied item scores (breathing, negative_vocalization, facial_expression, body_language, consolability). No clinical interpretation, pain diagnosis, or treatment recommendation is provided.
