Not a medical device. Not a diagnosis, dose, or listing recommendation.

What it computes

Sum five caller-assigned McPherson 2012 GMAWS integers (0-2) and return the published total (max 10) and Figure 1 score-group band.

When to use

When an agent has already assigned McPherson 2012 Figure 1 item integers (tremor, sweating, hallucination, orientation, agitation) and needs the published GMAWS total and score-group band, not a benzodiazepine or treatment order.

When not to use

  • Not a medical device and not a benzodiazepine, symptom-triggered, or treatment order.
  • Each of the five items is a caller-assigned integer 0, 1, or 2 from McPherson 2012 Figure 1. magent does not observe the patient.
  • Temperature is not an item. McPherson 2012 studied temperature then removed it from the post-temperature GMAWS used here.
  • Returned bands are McPherson 2012 Figure 1 score groups (zero, 1_to_3, 4_to_8, 9_to_10), not diazepam or chlordiazepoxide treatment orders.

Formula

GMAWS = tremor + sweating + hallucination + orientation + agitation; each caller-assigned 0-2; max 10

Given: agitation=0hallucination=0orientation=0sweating=0tremor=0

  1. tremor 0 + sweating 0 + hallucination 0 + orientation 0 + agitation 0
  2. Score = 0 (max 10); gmaws_band zero

All items 2

Given: agitation=2hallucination=2orientation=2sweating=2tremor=2

  1. tremor 2 + sweating 2 + hallucination 2 + orientation 2 + agitation 2
  2. Score = 10 (max 10); gmaws_band 9_to_10

Parameters

Name Type Required Description
tremor integer required Caller-assigned McPherson 2012 Figure 1 tremor (integer 0-2): 0 no tremor; 1 on movement; 2 at rest. magent does not observe the patient.
sweating integer required Caller-assigned McPherson 2012 Figure 1 sweating (integer 0-2): 0 no sweat visible; 1 moist; 2 drenching sweats. magent does not observe the patient.
hallucination integer required Caller-assigned McPherson 2012 Figure 1 hallucination (integer 0-2): 0 not present; 1 dissuadable; 2 not dissuadable. magent does not observe the patient.
orientation integer required Caller-assigned McPherson 2012 Figure 1 orientation (integer 0-2): 0 orientated; 1 vague/detached; 2 disorientated, no contact. magent does not observe the patient.
agitation integer required Caller-assigned McPherson 2012 Figure 1 agitation (integer 0-2): 0 calm; 1 anxious; 2 panicky. magent does not observe 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.

POST /api/calc/gmaws 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.

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.
