# Rogers 2011 Aortic Dissection Detection Risk Score (ADD-RS) > Rogers 2011 Aortic Dissection Detection Risk Score (ADD-RS) 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). Calculates the Rogers 2011 ADD-RS for aortic dissection risk stratification by summing one point per high-risk category (conditions, pain features, exam features) with a maximum score of 3. ## Facts - Endpoint: GET https://api.magentlab.com/api/calc/add_rs - Price: $0.005/call - Payment: x402 - Status: unknown - Last checked: 2026-09-15 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/rogers-2011-aortic-dissection-detection-risk-score-add-rs-8921fdbe - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_sdaRHiIJb9HXEjn-UxJVV 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 rogers-2011-aortic-dissection-detection-risk-score-add-rs-8921fdbe ``` Example prompt: Score this patient for aortic dissection using the Rogers ADD-RS: they have known Marfan syndrome and a family history of aortic disease, the pain was sudden and severe with a ripping quality, and on exam they have a pulse deficit and new aortic insufficiency murmur — no hypotension, no recent aortic manipulation, no known thoracic aneurysm or aortic valve disease, no focal neuro deficit. ## When to prefer this Use this endpoint when you need a fast, deterministic calculation of the Rogers 2011 ADD-RS for aortic dissection risk stratification in an emergency or clinical decision-support context. Prefer it over manual scoring to avoid arithmetic errors and to get structured output with risk banding. Not a substitute for the ADvISED D-dimer rule-out protocol or clinical imaging decisions. ## Known failure modes - Missing required boolean query parameters returns a validation error - Non-boolean values for flag fields cause a 400 error - Payment failure (x402) if USDC not provided or insufficient - Network timeout if the API is temporarily unavailable ## How this service works Rogers 2011 aortic dissection detection risk score (ADD-RS). One point per high-risk category with any marker (conditions, pain features, exam features); two markers in the same category still add only 1; max 3. Bands 0 / 1 / 2-3. Deterministic published score with citation. Not an imaging order, not ADvISED D-dimer rule-out; score 0 does not exclude dissection. ## Output Returns the computed ADD-RS integer score (0–3), the corresponding risk band (0, 1, or 2–3), a breakdown of points assigned per clinical category (conditions, pain features, exam features), and a citation to Rogers 2011. Score 0 does not exclude dissection; the result is a published deterministic clinical score, not an imaging order or D-dimer rule-out. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET", "HEAD", "DELETE" ], "type": "string" }, "headers": { "type": "object", "additionalProperties": { "type": "string" } }, "queryParams": { "type": "object", "required": [ "marfan_or_connective_tissue", "family_aortic_disease", "known_aortic_valve_disease", "recent_aortic_manipulation", "known_thoracic_aneurysm", "pain_sudden", "pain_severe", "pain_ripping_or_tearing", "pulse_deficit_or_sbp_differential", "focal_neuro_deficit_with_pain", "new_ai_murmur_with_pain", "hypotension_or_shock" ], "properties": { "pain_severe": { "type": "boolean", "description": "Chest, back, or abdominal pain of severe intensity (Rogers 2011 high-risk pain feature). true or false." }, "pain_sudden": { "type": "boolean", "description": "Chest, back, or abdominal pain of abrupt onset (Rogers 2011 high-risk pain feature). true or false." }, "hypotension_or_shock": { "type": "boolean", "description": "Hypotension or shock state (Rogers 2011 high-risk exam feature). true or false." }, "family_aortic_disease": { "type": "boolean", "description": "Family history of aortic disease (Rogers 2011 high-risk condition). true or false." }, "known_thoracic_aneurysm": { "type": "boolean", "description": "Known thoracic aortic aneurysm (Rogers 2011 high-risk condition). true or false." }, "new_ai_murmur_with_pain": { "type": "boolean", "description": "New murmur of aortic insufficiency in conjunction with pain (Rogers 2011 high-risk exam feature). true or false.
