Urticaria Activity Score (UAS7)

UAS

Sum Młynek 2008 EAACI/GA2LEN/EDF urticaria activity score over seven consecutive days: each day wheals 0-3 plus pruritus 0-3 (daily UAS 0-6). Return UAS7 (0-42) and mean_daily_uas. This paper published no UAS7 activity bands.

Not a medical device. Not a diagnosis, dose, or listing recommendation.

What it computes

Sum Młynek 2008 EAACI/GA2LEN/EDF urticaria activity score over seven consecutive days: each day wheals 0-3 plus pruritus 0-3 (daily UAS 0-6). Return UAS7 (0-42) and mean_daily_uas. This paper published no UAS7 activity bands.

When to use

When an agent already has seven consecutive days of caller-assigned UAS wheals and pruritus integers (0-3) and needs the published UAS7 and mean daily UAS. magent does not count wheals, grade pruritus, diagnose urticaria, or score angioedema activity (AAS).

When not to use

• Not a medical device and not a diagnosis of urticaria or a treatment order. magent does not count wheals or grade pruritus. Each of the 14 values is a caller-assigned integer 0-3.
• Młynek 2008 found quality-of-life correlation plateaued from the fourth consecutive day. magent still requires seven complete days and does not impute missing days.
• This is EAACI/GA2LEN/EDF UAS (daily wheals plus pruritus; UAS7 0-42), not angioedema activity (AAS).
• Młynek 2008 published no UAS7 activity-band cutpoints. magent returns UAS7 and mean_daily_uas only.

Formula

UAS7 = (wheals_d1 + pruritus_d1) + (wheals_d2 + pruritus_d2) + (wheals_d3 + pruritus_d3) + (wheals_d4 + pruritus_d4) + (wheals_d5 + pruritus_d5) + (wheals_d6 + pruritus_d6) + (wheals_d7 + pruritus_d7); each integer 0-3 (Młynek 2008 EAACI/GA2LEN/EDF UAS: wheals 0 none, 1 mild <20 wheals/24h, 2 moderate 20-50/24h, 3 intense >50/24h or large confluent areas; pruritus 0 none, 1 mild present but not annoying, 2 moderate troublesome without interfering with activity or sleep, 3 intense interferes with activity or sleep); daily UAS 0-6; UAS7 0-42; mean_daily_uas = UAS7 / 7; seven complete days required; no missing-day imputation; this paper published no UAS7 activity bands

Call

Expect HTTP 402 until you retry with PAYMENT-SIGNATURE. Incomplete query params return HTTP 400 before any quote or charge.

curl -i -H "Accept: application/json" "https://api.magentlab.com/api/calc/uas?wheals_d1=1&wheals_d2=0&wheals_d3=0&wheals_d4=0&wheals_d5=0&wheals_d6=0&wheals_d7=0&pruritus_d1=1&pruritus_d2=0&pruritus_d3=0&pruritus_d4=0&pruritus_d5=0&pruritus_d6=0&pruritus_d7=0"

Parameters

Bulk (POST)

POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement.

POST /api/calc/uas Max 25 unit_amount + extra_item_amount * (n - 1) extra $0.002 PREVIEW

• 1 to 25 items. Each item uses the same keys as the GET query parameters.
• POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows.
• The first invalid item fails the whole request (index in the 400 JSON). You are not charged.
• HTTP 200 is {count, path, items}. Each items[i] is the GET 200 body for that row.
• Catalog misses (empty matches, found=false) stay paid 200s inside that slot.
• x402 resource URL is this path plus n and body_sha256. Browsers that prefer text/html get the same paywall as GET; Pay retries POST with the same items.

Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, invalid params return HTTP 400 JSON before settlement. magent does not charge. Fix the params, then request a new 402 quote for that complete URL. Catalog misses (empty matches, found=false) are valid paid 200s. Unpaid valid requests return HTTP 402 with a base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote: retry the same PAYMENT-SIGNATURE. Full handshake and shared payment errors: Payments. Stdio MCP: /docs/mcp.

Guarantees

• HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged. HTTP 402 never includes the tool JSON.
• exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. Uncertain or failed settlement fails closed (HTTP 503). Retry the same PAYMENT-SIGNATURE.
• HTTP 402 is unpaid only. Do not sign a second authorization because of a 503.
• Execution is timeout-bounded and concurrency-capped.
• Calculator inputs are stored encrypted for allowlisted operators (Magent Console). They are not in public logs, SSH lookups, catalog, or rollups. Request logs store path without query.
