What it computes
Return the Gill 2005 Simplified Motor Score (0-2) from a caller-assigned motor category: obeys commands (2), localizes pain (1), or withdrawal to pain or less (0).
When to use
When an agent needs the published Gill 2005 Simplified Motor Score and must not invent a GCS total, a simplified verbal score, or a triage or intubation order.
When not to use
- Not a GCS replacement protocol and not a triage or intubation order.
- Not a medical device and not a diagnosis. magent does not examine the patient.
- Motor is caller-assigned as obeys, localizes, or withdrawal_or_less. This is Gill 2005 Simplified Motor Score only, not the simplified verbal score and not full GCS.
Formula
SMS = 2 if motor=obeys (obeys commands), 1 if motor=localizes (localizes pain), 0 if motor=withdrawal_or_less (withdrawal to pain or less); Gill 2005 Simplified Motor Score; max 2

Worked example
Obeys commands
Given:
motor=obeys
- motor=obeys → 2 (obeys commands)
- Score = 2 (max 2)
Localizes pain
Given:
motor=localizes
- motor=localizes → 1 (localizes pain)
- Score = 1 (max 2)
Withdrawal to pain or less
Given:
motor=withdrawal_or_less
- motor=withdrawal_or_less → 0 (withdrawal to pain or less)
- Score = 0 (max 2)

return HTTP 400 before any quote or charge.

Parameters
| Name | Type | Required | Description |
|---|---|---|---|
motor |
string | required · obeys, localizes, withdrawal_or_less | Gill 2005 Simplified Motor Score motor category as assigned by the caller. obeys (2, obeys commands), localizes (1, localizes pain), or withdrawal_or_less (0, withdrawal to pain or less). magent does not examine the patient. |
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.
- 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.
Example request (fixture)
{
"items": [
{
"motor": "obeys"
},
{
"motor": "obeys"
}
]
}
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
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.
- 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.
