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

What it computes

Apply the Maldonado 2014 PAWSS Part A threshold and ten yes/no items and return the published 0–10 total with the ≥4 high-risk band.

When to use

When an agent has already assigned the PAWSS threshold and ten item flags and needs the published score and high-risk cutoff, not a later prophylaxis protocol.

When not to use

Not a medical device and not a diagnosis of alcohol withdrawal syndrome (AWS) or a prophylaxis order.
Not CIWA-Ar.
The Part A threshold (any alcohol in the last 30 days or positive BAL on admission) is required. If it is false, magent returns score 0 and pawss_band outside_window and does not add the ten item points.
magent does not interview the patient or measure BAL. Each flag is caller-assigned.
Published cutoff is ≥4 high risk for complicated AWS. Scores 0–3 with a true threshold are low. magent does not invent a moderate class.

Formula

PAWSS = if alcohol_last_30d_or_positive_bal then recently_intoxicated_30d + alcohol_rehab + previous_withdrawal + blackouts + withdrawal_seizures + delirium_tremens + combined_downers_90d + combined_other_substances_90d + bal_ge_200 + increased_autonomic_activity else 0; each item 1 if true; Part A threshold 0 points; max 10; threshold false → outside_window; 0-3 low; >=4 high; Maldonado 2014

Parameters

Name	Type	Required	Description
`alcohol_last_30d_or_positive_bal`	boolean	required	Part A threshold (0 points). Caller-assigned: consumed any alcohol in the last 30 days or a positive BAL on admission (Maldonado 2014). If false, score is 0 and pawss_band is outside_window; the ten items are not added. magent does not interview the patient or measure BAL.
`recently_intoxicated_30d`	boolean	required	Recently intoxicated or drunk within the last 30 days as assigned by the caller (Maldonado 2014). true scores 1 when the Part A threshold is true. magent does not interview the patient.

`withdrawal_seizures`	boolean	required	Ever alcohol withdrawal seizures as assigned by the caller (Maldonado 2014). true scores 1 when the Part A threshold is true. magent does not interview the patient.
`delirium_tremens`	boolean	required	Ever delirium tremens as assigned by the caller (Maldonado 2014). true scores 1 when the Part A threshold is true. magent does not interview the patient.
`combined_downers_90d`	boolean	required	Combined alcohol with benzodiazepines or barbiturates in the last 90 days as assigned by the caller (Maldonado 2014). true scores 1 when the Part A threshold is true. magent does not interview the patient.
`combined_other_substances_90d`	boolean	required	Combined alcohol with any other substance of abuse in the last 90 days as assigned by the caller (Maldonado 2014). true scores 1 when the Part A threshold is true. magent does not interview the patient.
`bal_ge_200`	boolean	required	BAL on presentation ≥200 as assigned by the caller (Maldonado 2014). true scores 1 when the Part A threshold is true. magent does not measure BAL.
`increased_autonomic_activity`	boolean	required	Increased autonomic activity as assigned by the caller (Maldonado 2014), for example HR>120, tremor, sweating, agitation, or nausea. true scores 1 when the Part A threshold is true. 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/pawss 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.
