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

What it computes

Sum the ten Sullivan 1989 CIWA-Ar items (nine caller-assigned 0-7 plus orientation 0-4) and return the published total (max 67).

When to use

When an agent has already assigned Sullivan 1989 item integers and needs the published CIWA-Ar total, not a later benzodiazepine protocol cutoff.

When not to use

Not a diagnosis and not a benzodiazepine, symptom-triggered, or treatment order.
Items are caller-assigned Sullivan 1989 integers. magent does not observe the patient.
Nine items (nausea_vomiting, tremor, paroxysmal_sweats, anxiety, agitation, tactile, auditory, visual, headache) are 0-7. orientation is 0-4 and is not a 0-7 item.
Sullivan 1989 published the instrument and item ranges only. magent does not apply later protocol treatment cutoffs.

Formula

CIWA-Ar = nausea_vomiting + tremor + paroxysmal_sweats + anxiety + agitation + tactile + auditory + visual + headache + orientation; nine items 0-7, orientation 0-4; max 67

Parameters

Name	Type	Required	Description
`nausea_vomiting`	integer	required	Caller-assigned Sullivan 1989 nausea and vomiting points (integer 0-7). magent does not observe the patient.
`tremor`	integer	required	Caller-assigned Sullivan 1989 tremor points (integer 0-7). magent does not observe the patient.
`paroxysmal_sweats`	integer	required	Caller-assigned Sullivan 1989 paroxysmal sweats points (integer 0-7). magent does not observe the patient.
`anxiety`	integer	required	Caller-assigned Sullivan 1989 anxiety points (integer 0-7). magent does not observe the patient.
`agitation`	integer	required	Caller-assigned Sullivan 1989 agitation points (integer 0-7). magent does not observe the patient.
`tactile`	integer	required	Caller-assigned Sullivan 1989 tactile disturbances points (integer 0-7). magent does not observe the patient.
`auditory`	integer	required	Caller-assigned Sullivan 1989 auditory disturbances points (integer 0-7). magent does not observe the patient.
`visual`	integer	required	Caller-assigned Sullivan 1989 visual disturbances points (integer 0-7). magent does not observe the patient.
`headache`	integer	required	Caller-assigned Sullivan 1989 headache / fullness in head points (integer 0-7). 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/ciwa_ar 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.
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.
