# UAS7 Urticaria Activity Score Calculator

> UAS7 Urticaria Activity Score Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Computes the 7-day Urticaria Activity Score (UAS7) and mean daily UAS from seven days of caller-supplied wheals and pruritus integer ratings using the Młynek 2008 EAACI/GA2LEN/EDF scale

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 uas7-urticaria-activity-score-calculator-8210224c
```

Example prompt: Calculate the UAS7 score for a patient whose wheals scores over the past 7 days were 2, 3, 1, 2, 2, 1, 0 and whose pruritus scores were 2, 2, 1, 2, 1, 1, 0.

## When to prefer this

Use this endpoint when you need a standardized, validated UAS7 computation per the Młynek 2008 EAACI/GA2LEN/EDF protocol. Prefer it over manual arithmetic when building clinical dashboards, trial data pipelines, or patient-facing urticaria tracking apps where reproducibility and protocol fidelity matter. Not suitable when you need wheal counting (caller must supply pre-counted integers), AAS (Angioedema Activity Score), or any diagnostic output.

## Known failure modes

- Missing any of the 14 required query parameters returns a validation error
- Values outside the 0-3 integer enum are rejected
- Floating-point or non-integer values are rejected
- Fewer than 7 days of data provided results in an error — no missing-day imputation is performed

## How this service works

Młynek 2008 EAACI/GA2LEN/EDF UAS: seven days of wheals and pruritus integers 0-3. Daily UAS is wheals plus pruritus (0-6). UAS7 is the seven-day sum (0-42). Returns mean_daily_uas. Wheals 0 none, 1 mild (<20/24h), 2 moderate (20-50/24h), 3 intense (>50/24h or confluent). Pruritus 0 none, 1 mild, 2 moderate, 3 intense (interferes with activity or sleep). Seven complete days; no missing-day imputation. Not a diagnosis, not AAS. magent does not count wheals. Not a medical device.

## Output

Returns the mean_daily_uas (average of the seven daily UAS values) and implicitly the UAS7 total (sum of daily scores over 7 days, range 0-42), computed from the 14 input integers (7 wheals + 7 pruritus, each 0-3). Does not diagnose, does not count wheals, and does not impute missing days.
