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

What it computes

Sum ten caller-assigned Galer 1997 NPS integers (0-10) printed as Intense, Sharp, Hot, Dull, Cold, Sensitive, Itchy, Unpleasant, Deep, and Surface, and return that total (max 100).

When to use

When an agent already has Galer 1997 0-10 integers for those ten printed qualities and needs their sum, not a neuropathy diagnosis, interview, or later composite cutoff.

When not to use

Not a medical device and not a diagnosis of neuropathy or a treatment order.
Each of the ten items is a caller-assigned integer 0-10 from Galer 1997 Table 1 (Intense, Sharp, Hot, Dull, Cold, Sensitive, Itchy, Unpleasant, Deep, Surface). magent does not interview the patient.
Galer 1997 printed item-level 0-10 scores and did not print a diagnostic cutoff for a summed total. magent returns the sum of those ten items (max 100) without a neuropathy-yes/no threshold and does not apply later NPS4, NPS6, NPS8, or NPS10 composites.
The categorical time-quality item on that instrument is not a 0-10 score and is not an input.

Formula

NPS = intensity + sharpness + heat + dullness + cold + sensitive + itchy + unpleasantness + deep_pain + surface_pain; each caller-assigned 0-10; max 100; Galer 1997 Table 1 Intense, Sharp, Hot, Dull, Cold, Sensitive, Itchy, Unpleasant, Deep, Surface; no total-score cutoff

Worked example

All items 0

Given: cold=0deep_pain=0dullness=0heat=0intensity=0itchy=0sensitive=0sharpness=0surface_pain=0unpleasantness=0

intensity, sharpness, heat, dullness, cold, sensitive, itchy, unpleasantness, deep_pain, and surface_pain are 0 as assigned by the caller
Score = 0 (max 100). Galer 1997 published no total-score diagnostic cutoff.

Mixed printed items

Given: cold=0deep_pain=6dullness=1heat=2intensity=4itchy=0sensitive=0sharpness=3surface_pain=2unpleasantness=5

intensity 4 + sharpness 3 + heat 2 + dullness 1 + cold 0 + sensitive 0 + itchy 0 + unpleasantness 5 + deep_pain 6 + surface_pain 2
Score = 23 (max 100). No total-score diagnostic cutoff.

Parameters

Name	Type	Required	Description
`intensity`	integer	required	Caller-assigned Galer 1997 NPS intensity (integer 0-10; Table 1 Intense). magent does not interview the patient.
`sharpness`	integer	required	Caller-assigned Galer 1997 NPS sharpness (integer 0-10; Table 1 Sharp). magent does not interview the patient.
`heat`	integer	required	Caller-assigned Galer 1997 NPS heat (integer 0-10; Table 1 Hot). magent does not interview the patient.
`dullness`	integer	required	Caller-assigned Galer 1997 NPS dullness (integer 0-10; Table 1 Dull). magent does not interview the patient.
`cold`	integer	required	Caller-assigned Galer 1997 NPS cold (integer 0-10; Table 1 Cold). magent does not interview the patient.
`sensitive`	integer	required	Caller-assigned Galer 1997 NPS sensitive (integer 0-10; Table 1 Sensitive). magent does not interview the patient.
`itchy`	integer	required	Caller-assigned Galer 1997 NPS itchy (integer 0-10; Table 1 Itchy). magent does not interview the patient.
`unpleasantness`	integer	required	Caller-assigned Galer 1997 NPS overall unpleasantness (integer 0-10; Table 1 Unpleasant). magent does not interview the patient.
`deep_pain`	integer	required	Caller-assigned Galer 1997 NPS intensity of deep pain (integer 0-10; Table 1 Deep). magent does not interview the patient.
`surface_pain`	integer	required	Caller-assigned Galer 1997 NPS intensity of surface pain (integer 0-10; Table 1 Surface). magent does not interview 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/nps 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. 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.
