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

What it computes

Count how many of the three Rogers 2011 ADD-RS high-risk categories have at least one marker and return the published 0 / 1 / 2-3 band.

When to use

When an agent needs the published ADD-RS category count (0–3) and must not invent an imaging order, treat the score as ADvISED D-dimer rule-out, or treat score 0 as exclusion of dissection.

When not to use

• Not a medical device.
• Not an imaging order and not a diagnosis of aortic dissection.
• Not the ADvISED D-dimer rule-out pathway. magent does not interpret D-dimer.
• Score 0 does not exclude dissection. Rogers 2011 operationalizes the 2010 ACCF/AHA high-risk markers as three categories; two markers in one category still add only 1.
• Flags are caller-assigned. magent does not examine the patient.

Formula

ADD-RS = 1 if any high-risk condition (Marfan/connective tissue, family aortic disease, known aortic valve disease, recent aortic manipulation, known thoracic aneurysm) + 1 if any high-risk pain feature of chest/back/abdominal pain (sudden, severe, ripping/tearing) + 1 if any high-risk exam feature (pulse deficit or SBP differential, focal neurologic deficit with pain, new AI murmur with pain, hypotension or shock); two markers in the same category still add only 1; max 3; Rogers 2011 bands 0 / 1 / 2-3 (2010 ACCF/AHA high-risk markers)

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/add_rs?marfan_or_connective_tissue=false&family_aortic_disease=false&known_aortic_valve_disease=false&recent_aortic_manipulation=false&known_thoracic_aneurysm=false&pain_sudden=false&pain_severe=false&pain_ripping_or_tearing=false&pulse_deficit_or_sbp_differential=false&focal_neuro_deficit_with_pain=false&new_ai_murmur_with_pain=false&hypotension_or_shock=false"

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/add_rs 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.

Client errors (HTTP 400)

Invalid params return 400 without charge. Shared HTTP 402 and 503 meanings: Payments.

Related tools

• HEART score — Compute the HEART score as age points plus caller-assigned history, ECG, risk factors, and troponin (each 0-2).

• Killip — Return the Killip and Kimball 1967 myocardial-infarction heart-failure class 1-4 from a caller-assigned integer, with the published class description and 1967 CCU hospital mortality.

Payment

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.
• 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.
