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

  1. eye 4 + verbal 5 + motor 6
  2. Score = 15 (max 15)

1974 E4 V5 M5

Given: edition=1974eye=4motor=5verbal=5

  1. eye 4 + verbal 5 + motor 5
  2. Score = 14 (max 14)

1976 E1 V1 M1

Given: edition=1976eye=1motor=1verbal=1

  1. eye 1 + verbal 1 + motor 1
  2. 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.

POST /api/calc/gcs 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": [
    {
      "edition": "1976",
      "eye": "4",

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.
