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

What it computes

Return the Sessler 2002 Richmond Agitation-Sedation Scale term and description from a caller-assigned integer -5 to +4.

When to use

When an agent already has a RASS integer assigned as in Sessler 2002 and needs the published term and description. magent does not observe the patient, administer voice or physical stimulation, or titrate sedation. Not a CAM-ICU feature and not a sedation order.

When not to use

  • Not a medical device. magent does not examine the patient, administer voice or physical stimulation, or observe the ICU.
  • Not a CAM-ICU administration and not a CAM-ICU feature. Feature 4 of CAM-ICU is assigned separately.
  • Not a sedation order or dose. magent does not titrate sedation.
  • The caller assigns RASS -5 to +4. magent does not observe the patient.

Formula

RASS integer -5 to +4 as assigned by the caller; Sessler 2002 ten levels (Combative through Unarousable)

Call

Expect HTTP 402 until you retry with PAYMENT-SIGNATURE. Incomplete query params return HTTP 400 before any quote or charge.

Parameters

Name Type Required Description
rass integer required Sessler 2002 RASS integer -5 to +4 as assigned by the caller (+4 Combative; +3 Very agitated; +2 Agitated; +1 Restless; 0 Alert and calm; -1 Drowsy; -2 Light sedation; -3 Moderate sedation; -4 Deep sedation; -5 Unarousable). magent does not observe the patient, administer voice or physical stimulation, or titrate sedation.

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/rass 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.

Invalid params return 400 without charge. Shared HTTP 402 and 503 meanings: Payments.

HTTP Code When
400 invalid_rass rass must be an integer from -5 to 4 (Sessler 2002 Richmond Agitation-Sedation Scale). Returned before settlement; you are not charged.
400 invalid_items POST body must be a JSON object with only an items array Returned before settlement; you are not charged.
400 invalid_item_count items must be an array of 1 to 25 objects Returned before settlement; you are not charged.

Related tools

  • CAM-ICU — Apply the Ely 2001 CAM-ICU algorithm and return whether delirium is present from four caller-assigned features.
  • Glasgow Coma Scale — Compute the Glasgow Coma Scale as the sum of caller-assigned eye, verbal, and motor integers. The 1974 or 1976 edition is required.
  • FOUR score — Compute the FOUR score as the sum of caller-assigned eye, motor, brainstem, and respiration integers 0-4.

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.
