What it computes

Compute the Reilly 1988 paediatric Glasgow Coma Scale as the sum of caller-assigned eye (1-4), verbal (1-5), and motor (1-6) integers. Max 15.

When to use

When an agent already has paediatric eye, verbal, and motor integers after applying age-appropriate descriptors and needs the published PGCS total. magent does not observe the child, take age, or pick wording.

When not to use

  • Not a medical device. Not a diagnosis, trauma triage, or intubation order.
  • Not adult GCS 1974 five-point motor (Teasdale-Jennett 1974 motor 1-5, max 14). This is Reilly 1988 paediatric GCS with 1976-style motor 1-6 (max 15).
  • magent does not observe the patient and does not pick age-specific wording. The caller assigns eye, verbal, and motor after applying age-appropriate paediatric descriptors.
  • magent does not take age and does not implement an age-max expected-normal table.

Formula

PGCS = eye + verbal + motor; eye 1-4, verbal 1-5, motor 1-6; max 15

Call

Expect HTTP 402 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/pgcs?eye=4&verbal=5&motor=6"

Parameters

Name Type Required Description
eye integer required Eye opening (E). Integer 1-4 as assigned by the caller after age-appropriate paediatric descriptors. magent does not observe the child.
verbal integer required Verbal response (V). Integer 1-5 as assigned by the caller after age-appropriate paediatric descriptors. magent does not observe the child.
motor integer required Motor response (M). Integer 1-6 as assigned by the caller after age-appropriate paediatric descriptors. magent does not observe the child.

Bulk (POST)

POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement.

POST /api/calc/pgcs Max 25 unit_amount + extra_item_amount * (n - 1) extra $0.002 PREVIEW

  • 1 to 25 items. Each item uses the same keys as the GET query parameters.
  • POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows.
  • 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.

Related tools

Payment

Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, 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. Stdio MCP: /docs/mcp.

Guarantees

  • HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged. HTTP 402 never includes the tool JSON.
  • exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. 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 stored encrypted for allowlisted operators (Magent Console). They are not in public logs, SSH lookups, catalog, or rollups. Request logs store path without query.
