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

What it computes

Sum the seven Bastuji-Garin 2000 SCORTEN risk factors from caller-assigned flags and return the 0–7 score and that paper's predicted in-hospital mortality token.

When to use

When an agent has already assigned the published Bastuji-Garin 2000 SI cutoffs as flags and needs the SCORTEN total and predicted in-hospital mortality band. magent does not measure labs or BSA, and does not diagnose TEN/SJS or order ICU care or IVIG.

When not to use

Not a medical device and not a diagnosis of TEN or SJS.
magent does not order ICU care or IVIG.
Each of the seven Bastuji-Garin 2000 risk factors is a caller-assigned flag using that paper's SI cutoffs. magent does not measure age, heart rate, BSA, urea, glucose, or bicarbonate, and does not convert BUN.
Predicted in-hospital mortality tokens are from Bastuji-Garin 2000 only (3.2%, 12.1%, 35.3%, 58.3%, 90%). Not ABCD-10.

Formula

SCORTEN = age_gt_40 + malignancy + heart_rate_gt_120 + epidermal_detachment_gt_10_percent + urea_gt_10_mmol_l + glucose_gt_14_mmol_l + bicarbonate_lt_20_mmol_l; each 1 if true; Bastuji-Garin 2000; max 7; predicted in-hospital mortality 0-1 3.2%, 2 12.1%, 3 35.3%, 4 58.3%, >=5 90%

All seven caller-assigned flags false → 0

Call

Expect HTTP 402 until you retry with PAYMENT-SIGNATURE. Incomplete query params return HTTP 400 before any quote or charge.

Parameters

Name	Type	Required	Description
`age_gt_40`	boolean	required	Age >40 years (Bastuji-Garin 2000). true or false as assigned by the caller. magent does not compute age.
`malignancy`	boolean	required	Presence of malignancy (Bastuji-Garin 2000). true or false as assigned by the caller. magent does not diagnose cancer.
`heart_rate_gt_120`	boolean	required	Heart rate >120 beats/min (Bastuji-Garin 2000). true or false as assigned by the caller. magent does not measure heart rate.
`epidermal_detachment_gt_10_percent`	boolean	required	Epidermal detachment >10% of body surface area (Bastuji-Garin 2000). true or false as assigned by the caller. magent does not measure BSA.
`urea_gt_10_mmol_l`	boolean	required	Serum urea >10 mmol/L (Bastuji-Garin 2000; equivalent BUN >28 mg/dL). true or false as assigned by the caller. magent does not assay urea or convert BUN.
`glucose_gt_14_mmol_l`	boolean	required	Serum glucose >14 mmol/L (Bastuji-Garin 2000). true or false as assigned by the caller. magent does not assay glucose.
`bicarbonate_lt_20_mmol_l`	boolean	required	Serum bicarbonate <20 mmol/L (Bastuji-Garin 2000). true or false as assigned by the caller. magent does not assay bicarbonate.

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/scorten 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_flag`	boolean clinical flags must be true or false 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.

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.
