What it computes

Return the Schwab and England 1969 ADL percent 0-100 from a caller-assigned integer, with a stable label.

When to use

When an agent already has a Schwab and England ADL percent 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100 as in Schwab and England 1969 and needs the published score and label. magent does not observe the patient or assign ADL percent. Not Hoehn and Yahr. Not Karnofsky.

When not to use

Not a medical device. magent does not observe the patient.
Schwab and England 1969 ADL decades 0-100 including 0% vegetative. The caller assigns adl_percent. magent does not examine the patient.
Not Hoehn and Yahr and not Karnofsky. Stable adl_label tokens are not a published class.

Formula

Schwab and England ADL = caller-assigned integer 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100 (Schwab and England 1969); max 100; 0% vegetative is scored

Worked example

ADL 100 completely independent

Given: adl_percent=100

adl_percent 100 → score 100; max 100; adl_percent 100; completely_independent

ADL 0 vegetative

Given: adl_percent=0

adl_percent 0 → score 0; max 100; adl_percent 0; vegetative

Parameters

Name	Type	Required	Description
`adl_percent`	integer	required	Schwab and England 1969 ADL percent 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100 as assigned by the caller (100 completely independent, able to do all chores without slowness, difficulty or impairment; 90 completely independent with some slowness, difficulty and/or impairment, might take twice as long; 80 completely independent in most chores, takes twice as long; 70 not completely independent, more difficulty with some chores, three to four times as long in some; 60 some dependency, can do most chores but exceedingly slowly and with much effort; 50 more dependent, help with half, difficulty with everything; 40 very dependent, can assist with all chores but few alone; 30 with effort now and then does a few chores alone, much help needed; 20 nothing alone, can be a slight help with some chores; 10 totally dependent, helpless; 0 vegetative functions such as swallowing, bladder and bowel functions are not functioning, bedridden). 0% vegetative is scored. 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/schwab_england 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": [
    {
      "adl_percent": "100"
    },
    {
      "adl_percent": "100"
    }

}

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.
