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
- appearance 1 + pulse 2 + grimace 1 + activity 2 + respiration 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.
- 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",
"respiration": "2"
},
{
"activity": "2",
"appearance": "1",
"grimace": "1",
"pulse": "2",
"respiration": "2"
}
]
}
Opens a two-item fixture on the API host. Unpaid browsers get the same MetaMask paywall as GET; Pay retries POST with those items.

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.
