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

What it computes

Apply the Than 2012 ADAPT 2-hour accelerated diagnostic protocol and return whether a caller-assigned TIMI UA/NSTEMI score plus initial ECG and 0-hour/2-hour troponin flags meet the published ADP-negative (low-risk) rule.

When to use

When an agent already has a caller-assigned Antman 2000 TIMI UA/NSTEMI total (0-7) and caller-assigned flags for new ischemic ECG changes and 0-hour and 2-hour troponin elevation and needs the published Than 2012 ADP-negative result. magent does not assign TIMI items, read an ECG, or assay troponin.

When not to use

• Not a medical device and not a diagnosis of ACS.
• timi_score is the caller-assigned Antman 2000 TIMI UA/NSTEMI total (0-7). magent does not assign TIMI items.
• new_ischemic_ecg is a caller-assigned flag for new ischemic changes on the initial ECG (not known to be pre-existing). magent does not read an ECG.
• troponin_0_elevated and troponin_2h_elevated are caller-assigned flags for 0-hour and 2-hour (not 3-hour) cTnI at or above the institutional cutoff. magent does not assay troponin.
• This tool is not a discharge order or a stress-test order. Presence of high-risk features does not mandate a test.
• This is the Than 2012 ADAPT protocol (TIMI 0 plus no new ischemic ECG plus both 0h/2h troponins not elevated), not HEART Pathway (Mahler 2015 HEART 0-3 plus 0h/3h) and not TIMI item scoring.

Formula

low_risk iff timi_score == 0 and new_ischemic_ecg is false and troponin_0_elevated is false and troponin_2h_elevated is false; timi_score is the caller-assigned Antman 2000 TIMI UA/NSTEMI total 0-7; ECG and troponin flags are caller-assigned (Than 2012 ADAPT Table 1)

Call

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

curl -i -H "Accept: application/json" "https://api.magentlab.com/api/calc/adapt?timi_score=0&new_ischemic_ecg=false&troponin_0_elevated=false&troponin_2h_elevated=false"

Parameters

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/adapt 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.

• HEART Pathway — Apply the Mahler 2015 HEART Pathway and return whether a caller-assigned HEART score plus 0-hour and 3-hour troponin flags meet the published early-discharge rule.
• TIMI UA/NSTEMI — Compute the TIMI risk score for unstable angina / NSTEMI from age and six caller-assigned flags.

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.
