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

What it computes

Count Kessler 2005 clinically significant ASRS v1.1 Part A items (six caller-assigned 0-4 frequencies) and return whether four or more are in the published range.

When to use

When an agent has already assigned Kessler 2005 0-4 integers for each of the six ASRS v1.1 Part A items and needs the published 4-of-6 screen, not an ADHD diagnosis or the 18-item ASRS.

When not to use

Not a medical device and not an ADHD diagnosis or treatment order.
Each of the six Part A items is a caller-assigned integer 0-4 (0 never, 1 rarely, 2 sometimes, 3 often, 4 very often). magent does not interpret the items and does not interview the patient.
This is Kessler 2005 ASRS v1.1 6-item screener (Part A) only. magent does not score the 18-item ASRS or later 0-24 sum cutoffs.
wrap_up, organization, and remembering are clinically significant at sometimes or more (≥2). avoid_delay, fidget, and motor are clinically significant at often or more (≥3) (Kessler 2005 Table 1 footnotes). Screen-positive at ≥4 of 6 (Table 4 highest stratum). It is a screen, not a diagnosis.

Formula

ASRS Part A = count of Kessler 2005 clinically significant items among wrap_up, organization, remembering, avoid_delay, fidget, motor; wrap_up/organization/remembering ≥2 (sometimes); avoid_delay/fidget/motor ≥3 (often); screen-positive at ≥4; max 6

Worked example

All items never

Given: avoid_delay=0fidget=0motor=0organization=0remembering=0wrap_up=0

wrap_up 0, organization 0, remembering 0, avoid_delay 0, fidget 0, motor 0: none clinically significant
Score = 0 (max 6); screen_positive false (threshold is ≥4)

Four clinically significant items at published floors

Given: avoid_delay=3fidget=0motor=0organization=2remembering=2wrap_up=2

wrap_up 2, organization 2, and remembering 2 count (≥ sometimes); avoid_delay 3 counts (≥ often); fidget 0 and motor 0 do not
Score = 4; screen_positive true

Parameters

Name	Type	Required	Description
`wrap_up`	integer	required	Caller-assigned Kessler 2005 ASRS v1.1 Part A item 1 (integer 0-4): how often do you have trouble wrapping up the fine details of a project, once the challenging parts have been done? (0 never, 1 rarely, 2 sometimes, 3 often, 4 very often). Clinically significant at sometimes or more. magent does not interpret the item.
`organization`	integer	required	Caller-assigned Kessler 2005 ASRS v1.1 Part A item 2 (integer 0-4): how often do you have difficulty getting things in order when you have to do a task that requires organization? Clinically significant at sometimes or more. magent does not interpret the item.
`remembering`	integer	required	Caller-assigned Kessler 2005 ASRS v1.1 Part A item 3 (integer 0-4): how often do you have problems remembering appointments or obligations? Clinically significant at sometimes or more. magent does not interpret the item.
`avoid_delay`	integer	required	Caller-assigned Kessler 2005 ASRS v1.1 Part A item 4 (integer 0-4): when you have a task that requires a lot of thought, how often do you avoid or delay getting started? Clinically significant at often or more. magent does not interpret the item.
`fidget`	integer	required	Caller-assigned Kessler 2005 ASRS v1.1 Part A item 5 (integer 0-4): how often do you fidget or squirm with your hands or your feet when you have to sit down for a long time? Clinically significant at often or more. magent does not interpret the item.
`motor`	integer	required	Caller-assigned Kessler 2005 ASRS v1.1 Part A item 6 (integer 0-4): how often do you feel overly active and compelled to do things, like you were driven by a motor? Clinically significant at often or more. magent does not interpret the item.

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/asrs 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.

Client errors (HTTP 400)

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

HTTP	Code	When
400	`invalid_asrs`	Each ASRS v1.1 Part A item must be an integer 0–4 (Kessler 2005 never to very often). 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.
400	`invalid_item`	each items entry must be a JSON object Returned before settlement; you are not charged.

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.
