What it computes
Compute the Glasgow Coma Scale as the sum of caller-assigned eye, verbal, and motor integers. The 1974 or 1976 edition is required.
When to use
When an agent needs a published Teasdale-Jennett GCS total and must not silently pick the 1974 five-point motor scale or the 1976 six-point motor scale.
When not to use
- Not a diagnosis and not a trauma triage, intubation, or disposition order.
- Eye, verbal, and motor are caller-supplied integers. magent does not observe the three signs.
- edition is required. magent does not pick 1974 (motor 1-5, max 14) or 1976 (motor 1-6, max 15).
Formula
GCS = eye + verbal + motor; eye 1-4, verbal 1-5, motor 1-6; max 15

Worked example
1976 E4 V5 M6
Given:
edition=1976eye=4motor=6verbal=5
- eye 4 + verbal 5 + motor 6
- Score = 15 (max 15)
1974 E4 V5 M5
Given:
edition=1974eye=4motor=5verbal=5
- eye 4 + verbal 5 + motor 5
- Score = 14 (max 14)
1976 E1 V1 M1
Given:
edition=1976eye=1motor=1verbal=1
- eye 1 + verbal 1 + motor 1
- Score = 3

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. HTTP 503 after a signature: retry the same
PAYMENT-SIGNATURE
— that is not a new 402.

Parameters
| Name | Type | Required | Description |
|---|---|---|---|
eye |
integer | required | Eye opening (E). Integer 1-4 as assigned by the caller. |
verbal |
integer | required | Verbal response (V). Integer 1-5 as assigned by the caller. |
motor |
integer | required | Motor response (M). Integer 1-5 when edition=1974, or 1-6 when edition=1976, as assigned by the caller. |
edition |
string | required · 1974, 1976 | Published motor scale. Required; magent does not pick 1974 (motor 1-5) or 1976 (motor 1-6). |
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": [
{
"edition": "1976",
"eye": "4",
"motor": "6",
"verbal": "5"
},
{
"edition": "1976",
"eye": "4",
"motor": "6",
"verbal": "5"
}
]
}
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. HTTP 503 is not a new quote: retry the same PAYMENT-SIGNATURE. 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 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 not persisted. Request logs store path without query.
