# Apgar score Status: WEDGE Price: $0.005 USDC `GET /api/calc/apgar` HTML: https://magentlab.com/docs/apgar Markdown: https://magentlab.com/docs/apgar.md Not a medical device. Not a diagnosis, dose, or listing recommendation. ## What it computes Compute the Apgar newborn evaluation score as the sum of five caller-assigned 0-2 signs. ## When to use When an agent needs the published Apgar total from five signs and must not invent the sum. ## When not to use - Not a diagnosis and not a resuscitation, prognosis, or discharge recommendation. - Each sign is a caller-supplied integer 0-2. magent does not observe color, heart rate, reflex, tone, or respiration. - Apgar 1953 defines the five signs and 0-2 points; it does not publish later 0-3 / 4-6 / 7-10 interpretation bands. ## Formula ``` APGAR = appearance + pulse + grimace + activity + respiration; each 0-2; max 10 ``` ## Citation A proposal for a new method of evaluation of the newborn infant Virginia Apgar Curr Res Anesth Analg. 1953;32(4):260-267 DOI: none ## Worked example ### Appearance 1, pulse 2, grimace 1, activity 2, respiration 2 Given: `activity=2, appearance=1, grimace=1, pulse=2, respiration=2` 1. appearance 1 + pulse 2 + grimace 1 + activity 2 + respiration 2 2. Score = 8 ## Parameters - `appearance` (integer, required): Color (A). Integer 0, 1, or 2 as assigned by the caller. - `pulse` (integer, required): Heart rate (P). Integer 0, 1, or 2 as assigned by the caller. - `grimace` (integer, required): Reflex irritability (G). Integer 0, 1, or 2 as assigned by the caller. - `activity` (integer, required): Muscle tone (A). Integer 0, 1, or 2 as assigned by the caller. - `respiration` (integer, required): Respiratory effort (R). Integer 0, 1, or 2 as assigned by the caller. ## Bulk (POST) POST the same path with a JSON items array. Price is n times the GET unit. Invalid items return HTTP 400 before settlement. Method: `POST /api/calc/apgar` Max items: 25 Price: unit_amount * n (unit 5000 atomic) Status: PREVIEW - 1 to 25 items. Each item uses the same keys as the GET query parameters. - 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. Example request: ```json { "items": [ { "activity": "2", "appearance": "1", "grimace": "1", "pulse": "2", "respiration": "2" }, { "activity": "2", "appearance": "1", "grimace": "1", "pulse": "2", "respiration": "2" } ] } ``` Human paywall (two-item fixture): https://api.magentlab.com/paywall/bulk/apgar Example 200: ```json { "count": 2, "path": "/api/calc/apgar", "items": [ { "components": [ { "value": 1, "factor": "appearance", "points": 1, "present": true }, { "value": 2, "factor": "pulse", "points": 2, "present": true }, { "value": 1, "factor": "grimace", "points": 1, "present": true }, { "value": 2, "factor": "activity", "points": 2, "present": true }, { "value": 2, "factor": "respiration", "points": 2, "present": true } ], "disclaimer": "Not a medical device.

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. ## Guarantees - Invalid query parameters return HTTP 400 before settlement. You are not charged. - Settlement finishes before the tool executes. Uncertain settlement fails closed (HTTP 503). - Execution is timeout-bounded and concurrency-capped. - Calculator inputs are not persisted. Request logs store path without query.
