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

What it computes

Sum five caller-assigned Warden 2003 PAINAD integers (0-2) and return the published total (max 10).

When to use

When an agent has already assigned Warden 2003 0-2 integers for breathing, negative vocalization, facial expression, body language, and consolability and needs the published total, not a pain diagnosis, analgesic order, or later intensity cutoff.

When not to use

Not a medical device and not a pain diagnosis or analgesic order.
Each of the five items is a caller-assigned integer 0, 1, or 2 from Warden 2003. magent does not observe the patient.
Total is 0-10. magent does not add intensity cutoffs that are not in Warden 2003.

Formula

PAINAD = breathing + negative_vocalization + facial_expression + body_language + consolability; each caller-assigned 0-2; max 10

Worked example

All items 0

Given: body_language=0breathing=0consolability=0facial_expression=0negative_vocalization=0

breathing 0 + negative_vocalization 0 + facial_expression 0 + body_language 0 + consolability 0
Score = 0 (max 10)

All items 2

Given: body_language=2breathing=2consolability=2facial_expression=2negative_vocalization=2

breathing 2 + negative_vocalization 2 + facial_expression 2 + body_language 2 + consolability 2
Score = 10 (max 10)

Parameters

Name	Type	Required	Description
`breathing`	integer	required	Caller-assigned Warden 2003 PAINAD breathing independent of vocalization (integer 0-2): 0 normal; 1 occasional labored breathing or short period of hyperventilation; 2 noisy labored breathing, long period of hyperventilation, or Cheyne-Stokes respirations. magent does not observe the patient.
`negative_vocalization`	integer	required	Caller-assigned Warden 2003 PAINAD negative vocalization (integer 0-2): 0 none; 1 occasional moan or groan, or low-level speech with a negative or disapproving quality; 2 repeated troubled calling out, loud moaning or groaning, or crying. magent does not observe the patient.
`facial_expression`	integer	required	Caller-assigned Warden 2003 PAINAD facial expression (integer 0-2): 0 smiling or inexpressive; 1 sad, frightened, or frown; 2 facial grimacing. magent does not observe the patient.
`body_language`	integer	required	Caller-assigned Warden 2003 PAINAD body language (integer 0-2): 0 relaxed; 1 tense, distressed pacing, or fidgeting; 2 rigid, fists clenched, knees pulled up, pulling or pushing away, or striking out. magent does not observe the patient.
`consolability`	integer	required	Caller-assigned Warden 2003 PAINAD consolability (integer 0-2): 0 no need to console; 1 distracted or reassured by voice or touch; 2 unable to console, distract, or reassure. 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/painad 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.

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.
