# Short Michigan Alcoholism Screening Test (SMAST) SMAST Status: LIVE Price: $0.005 USDC `GET /api/calc/smast` HTML: https://magentlab.com/docs/smast Markdown: https://magentlab.com/docs/smast.md Not a medical device. Not a diagnosis, dose, or listing recommendation. ## What it computes Count Selzer 1975 SMAST alcoholic-direction answers and return the published 0-1 nonalcoholic, 2 possible, and ≥3 alcoholic bands. ## When to use When an agent has already assigned the 13 SMAST yes/no items and needs that paper's scored total and cutoffs, not the 25-item MAST, Brief MAST, SMAST-G, or later clinic 0-2 / 3 / ≥4 tables. ## When not to use - Not a medical device. - Not a diagnosis of alcoholism or alcohol use disorder. - magent does not interview the patient. Each item is caller-assigned yes/no. - Scoring uses the Selzer 1975 alcoholic-direction key. feel_normal_drinker, friends_think_normal_drinker, and able_to_stop score 1 if false. magent does not award 1 point for every yes. - This is the 13-item SMAST only. Not the 25-item MAST, not Pokorny 1972 Brief MAST, and not SMAST-G. - Cutoffs are this paper's 0-1 nonalcoholic, 2 possible, and ≥3 alcoholic. magent does not apply later clinic 0-2 / 3 borderline / ≥4 tables. ## Formula ``` SMAST = (1 if not feel_normal_drinker) + relative_worry_or_complain + feel_guilty + (1 if not friends_think_normal_drinker) + (1 if not able_to_stop) + attended_aa + drinking_created_problems + trouble_at_work + neglected_obligations + gone_for_help + hospital_because_of_drinking + arrested_drunk_driving + arrested_drunken_behavior; each 1 in the Selzer 1975 alcoholic direction; max 13 ``` ## Citation [A self-administered Short Michigan Alcoholism Screening Test (SMAST)](https://doi.org/10.15288/jsa.1975.36.117) Selzer ML, Vinokur A, van Rooijen L J Stud Alcohol. 1975;36(1):117-126 DOI: [10.15288/jsa.1975.36.117](https://doi.org/10.15288/jsa.1975.36.117) ## Worked example ### All non-alcoholic answers Given: `able_to_stop=true, arrested_drunk_driving=false, arrested_drunken_behavior=false, attended_aa=false, drinking_created_problems=false, feel_guilty=false, feel_normal_drinker=true, friends_think_normal_drinker=true, gone_for_help=false, hospital_because_of_drinking=false, neglected_obligations=false, relative_worry_or_complain=false, trouble_at_work=false` 1. feel_normal_drinker, friends_think_normal_drinker, and able_to_stop are true (not scored) 2. the other ten items are false (not scored) 3. score = 0; band nonalcoholic ### Two alcoholic-direction answers Given: `able_to_stop=true, arrested_drunk_driving=false, arrested_drunken_behavior=false, attended_aa=true, drinking_created_problems=false, feel_guilty=true, feel_normal_drinker=true, friends_think_normal_drinker=true, gone_for_help=false, hospital_because_of_drinking=false, neglected_obligations=false, relative_worry_or_complain=false, trouble_at_work=false` 1. feel_guilty and attended_aa true 2. score = 2; band possible ### Three alcoholic-direction answers Given: `able_to_stop=true, arrested_drunk_driving=false, arrested_drunken_behavior=false, attended_aa=true, drinking_created_problems=false, feel_guilty=true, feel_normal_drinker=true, friends_think_normal_drinker=true, gone_for_help=false, hospital_because_of_drinking=false, neglected_obligations=false, relative_worry_or_complain=false, trouble_at_work=true` 1. feel_guilty, attended_aa, and trouble_at_work true 2. score = 3; band alcoholic ## Also searched as - Short Michigan Alcoholism Screening Test - SMAST - SMAST-13 - Selzer SMAST - short MAST - SMAST score - Michigan alcoholism short test - Selzer 1975 SMAST ## Parameters - `feel_normal_drinker` (boolean, required): Do you feel you are a normal drinker?

The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement. Method: `POST /api/calc/smast` Max items: 25 Price: unit_amount + extra_item_amount * (n - 1) (unit 5000 atomic, extra 2000 atomic) Status: 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.

Returned before settlement; you are not charged. - HTTP 400 `invalid_items`: POST body must be a JSON object with only an items array Returned before settlement; you are not charged. - HTTP 400 `invalid_item_count`: items must be an array of 1 to 25 objects Returned before settlement; you are not charged. - HTTP 400 `invalid_item`: each items entry must be a JSON object Returned before settlement; you are not charged. Shared HTTP 402 and 503: https://magentlab.com/docs/payments ## Related tools - [CAGE](https://magentlab.com/docs/cage) — Sum the four Ewing 1984 CAGE items and return whether two or more answers are affirmative. - [AUDIT-C](https://magentlab.com/docs/audit-c) — Sum three caller-assigned Bush 1998 AUDIT-C integers (0-4) and return this paper's ≥3 and ≥4 screens. - [CRAFFT](https://magentlab.com/docs/crafft) — Sum the six Knight 2002 CRAFFT items and return whether two or more answers are affirmative. ## 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. - GET the tool with Accept: application/json (do not send Accept: text/html unless you want the human paywall). - HTTP 402 means you have not paid. Decode the base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote. - Sign accepts[0] (exact, EIP-3009) with validBefore = now + maxTimeoutSeconds (600 seconds), or accepts[1] (batch-settlement deposit/voucher) on product GET. Ping and POST {items} stay exact. Magent retries transient facilitator 429/5xx before answering. - Retry the same URL with PAYMENT-SIGNATURE (base64 JSON of accepted and payload). Magent attaches canonical extensions.bazaar on CDP verify/settle; echoing 402 bazaar is optional. - Success is HTTP 200 JSON plus PAYMENT-RESPONSE. exact settles before the tool. batch-settlement verifies (and deposit-settles) before the tool and commits the charge after HTTP 2xx. HTTP 503: retry the same PAYMENT-SIGNATURE. Mint a new exact nonce only after a new HTTP 402. - offered `exact` on eip155:8453: Fixed-price USDC on Base. The buyer authorizes the advertised amount (EIP-3009). magent settles before the tool runs (paymentFlow upfront). extra.assetTransferMethod=eip3009 extra.paymentFlow=upfront. - offered `batch-settlement` on eip155:8453: Payment-channel vouchers claimed later in batches. Exact stays accepts[0]. Same-path POST {items} is still exact. extra.assetTransferMethod=eip3009 extra.paymentFlow=authorization. - not offered `upto`: Not offered. Usage-based: buyer authorizes a ceiling, seller settles the actual amount after work. Reserved for a future metered tool. Not for current calculators or code search. Same-path POST {items} is still scheme exact: one EIP-3009 authorization for GET unit plus $0.002 per extra item. That is not x402 batch-settlement (payment channels / vouchers). Shared HTTP 402 and 503 table: https://magentlab.com/docs/payments Stdio MCP (one process per host): https://magentlab.com/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.
