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

What it computes

Sum five caller-assigned Odhner 2003 original NVPS integers (0-2) and return the published total (max 10).

When to use

When an agent has already assigned Odhner 2003 original 0-2 integers for face, activity, guarding, physiologic I (vital signs), and physiologic II (autonomic) and needs the published total, not a pain diagnosis, analgesic order, later NVPS-R respiratory category, or invented 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 Odhner 2003. magent does not observe the patient.
Original Odhner 2003 NVPS only. Not the later NVPS-R that replaces physiologic II with a respiratory category.
Total is 0-10. magent does not add mild, moderate, or severe intensity cutoffs that are not in Odhner 2003.
Not BPS. Not FLACC.

Formula

NVPS = face + activity + guarding + physiologic_i + physiologic_ii; each caller-assigned 0-2; max 10

Worked example

All items 0

Given: activity=0face=0guarding=0physiologic_i=0physiologic_ii=0

face 0 + activity 0 + guarding 0 + physiologic_i 0 + physiologic_ii 0
Score = 0 (max 10)

All items 2

Given: activity=2face=2guarding=2physiologic_i=2physiologic_ii=2

face 2 + activity 2 + guarding 2 + physiologic_i 2 + physiologic_ii 2
Score = 10 (max 10)

Parameters

Name	Type	Required	Description
`face`	integer	required	Caller-assigned Odhner 2003 original NVPS face (integer 0-2): 0 no particular expression or smile; 1 occasional grimace, tearing, frowning, wrinkled forehead; 2 frequent grimace, tearing, frowning, wrinkled forehead. magent does not observe the patient.
`activity`	integer	required	Caller-assigned Odhner 2003 original NVPS activity/movement (integer 0-2): 0 lying quietly, normal position; 1 seeking attention through movement or slow, cautious movement; 2 restless, excessive activity and/or withdrawal reflexes. magent does not observe the patient.
`guarding`	integer	required	Caller-assigned Odhner 2003 original NVPS guarding (integer 0-2): 0 lying quietly, no positioning of hands over areas of the body; 1 splinting areas of the body, tense; 2 rigid, stiff. magent does not observe the patient.
`physiologic_i`	integer	required	Caller-assigned Odhner 2003 original NVPS physiologic I vital signs (integer 0-2): 0 stable vital signs (no change in past 4 h vs baseline BP/HR/RR); 1 change over past 4 h in SBP >20 mmHg or HR >20/min or RR >10/min; 2 change over past 4 h in SBP >30 mmHg or HR >25/min or RR >20/min. 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/nvps 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.

Example request (fixture)

  "items": [
    {
      "activity": "0",
      "face": "0",

Client errors (HTTP 400)

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

HTTP	Code	When
400	`invalid_nvps`	NVPS inputs must be the five caller-assigned 0-2 Odhner 2003 original categories (face, activity, guarding, physiologic_i, physiologic_ii). 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.
