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

What it computes

Sum the six Bangalore 2023 composite PE shock flags from caller-assigned booleans and return the 0–6 integer total. No named risk bands.

When to use

When an agent already has intermediate-risk (normotensive) PE findings assigned as six yes/no flags and needs the published 0–6 total, not a shock diagnosis, not sPESI, not Bova, and not PESI.

When not to use

Not a medical device and not a shock diagnosis. Not a reperfusion or thrombolysis order.
For intermediate-risk (normotensive) PE as in Bangalore 2023. Not high-risk hypotensive PE. Not sPESI, not Bova, and not PESI.
Six equally weighted caller-assigned flags. magent does not read echo or assays and does not take raw heart rate. Site troponin and BNP cutoffs were not standardized; this tool does not invent numeric biomarker thresholds.
Returns the 0–6 integer score and max_score only. Bangalore 2023 reported prevalence of normotensive shock by integer score 0–6 and that a score of 6 predicted shock versus <6. This tool does not invent named risk bands.

Formula

CPES = elevated_troponin + elevated_bnp + moderate_or_severe_rv_dysfunction + saddle_pe + concomitant_dvt + tachycardia; each 1 if true; max 6 (Bangalore 2023)

Worked example

All six flags false

Given: concomitant_dvt=falseelevated_bnp=falseelevated_troponin=falsemoderate_or_severe_rv_dysfunction=falsesaddle_pe=falsetachycardia=false

All six caller-assigned flags are false
Score = 0 (max 6); integer score only, no named band

All six flags true

Given: concomitant_dvt=trueelevated_bnp=trueelevated_troponin=truemoderate_or_severe_rv_dysfunction=truesaddle_pe=truetachycardia=true

All six caller-assigned flags are true (1 point each)
Score = 6 (max 6); integer score only, no named band

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
`elevated_troponin`	boolean	required	Elevated troponin per local assay, as assigned by the caller (Bangalore 2023). true scores 1; false scores 0. Site cutoffs were not standardized; magent does not invent a numeric threshold or read the assay.
`elevated_bnp`	boolean	required	Elevated BNP, as assigned by the caller (Bangalore 2023). true scores 1; false scores 0. Site cutoffs were not standardized; magent does not invent a numeric threshold or read the assay.
`moderate_or_severe_rv_dysfunction`	boolean	required	Moderately or severely reduced RV function, as assigned by the caller (Bangalore 2023). Normal or mild reduction is false. true scores 1; false scores 0. magent does not read echo.
`saddle_pe`	boolean	required	Saddle PE or central thrombus burden, as assigned by the caller (Bangalore 2023). true scores 1; false scores 0. magent does not read imaging.
`concomitant_dvt`	boolean	required	Concomitant DVT, as assigned by the caller (Bangalore 2023). true scores 1; false scores 0. magent does not diagnose DVT.
`tachycardia`	boolean	required	Tachycardia ≥100 beats/min as assigned by the caller (Bangalore 2023). true scores 1; false scores 0. magent does not take raw heart rate.

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/cpes 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.
