# AUA Symptom Index (Barry 1992) Calculator

> AUA Symptom Index (Barry 1992) Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

Computes the 7-item AUA Symptom Index score (0–35) from caller-supplied integer ratings for each lower urinary tract symptom domain

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 aua-symptom-index-barry-1992-calculator-6c662024
```

Example prompt: Calculate the AUA Symptom Index for a patient with these Barry 1992 ratings: incomplete emptying 3, frequency 4, intermittency 2, urgency 3, weak stream 4, straining 2, nocturia 3 — what's the total score out of 35?

## When to prefer this

Use this endpoint when you need a fast, deterministic arithmetic computation of the Barry 1992 AUA Symptom Index total from seven pre-collected integer item scores. Prefer it over manual addition when building clinical decision-support tools, EHR integrations, or research pipelines that need auditable, reproducible scoring. Note it does not take a voiding history, does not apply AUA severity bands, and does not include the IPSS quality-of-life question — choose a different tool if those outputs are needed.

## Known failure modes

- Missing any of the seven required query parameters returns an error
- Any score value outside the integer range 0–5 is invalid and may cause an error
- Non-integer values for score parameters will fail validation
- Network or payment authorization failure (x402 protocol) prevents the call from completing

## How this service works

Barry 1992 AUA-SI: seven caller-assigned integers 0-5 for incomplete emptying, frequency, intermittency, urgency, weak stream, straining (hesitancy), and nocturia. Sum 0-35. magent does not take a voiding history. Barry 1992 published no mild/moderate/severe total-score bands; later AUA-guideline 0-7/8-19/20-35 cuts are not applied. Not the 8-item IPSS quality-of-life question, not a BPH treatment order, and not a medical device.

## Output

Returns the summed AUA Symptom Index total (an integer from 0 to 35) calculated from the seven caller-supplied item scores. Does not apply mild/moderate/severe severity bands, does not include an IPSS quality-of-life item, and does not produce treatment recommendations.
