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

Worked example

Appearance 1, pulse 2, grimace 1, activity 2, respiration 2

Given: activity=2appearance=1grimace=1pulse=2respiration=2

  1. appearance 1 + pulse 2 + grimace 1 + activity 2 + respiration 2
  2. Score = 8

Try

Opens the live endpoint. Unpaid browser requests show the paywall; agents should send Accept: application/json.

/api/calc/apgar?appearance=1&pulse=2&grimace=1&activity=2&respiration=2

Full URL: https://api.magentlab.com/api/calc/apgar?appearance=1&pulse=2&grimace=1&activity=2&respiration=2

x402 V2 curl

Expect HTTP 402 and a PAYMENT-REQUIRED header 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/apgar?appearance=1&pulse=2&grimace=1&activity=2&respiration=2"

Cursor mcp.json

Intended config for @magent/mcp. This is not npm @x402/fetch (a payment fetch wrapper).

Parameters

Name Type Required Description
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.

POST /api/calc/apgar Max 25 unit_amount * n 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 (fixture)

{
  "items": [
    {
      "activity": "2",
      "appearance": "1",
      "grimace": "1",
      "pulse": "2",

Payment

Required query parameters must be present and valid. 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. Retry the same URL with PAYMENT-SIGNATURE. Settlement completes before the tool runs. Full handshake and shared payment errors: Payments.

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.
