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

What it computes

When to use

When an agent needs the Eddleston 2004 hourly atropine maintenance band from a caller-assigned total loading milligram amount and must not invent doubling-bolus titration, pralidoxime, or a diagnosis of organophosphate poisoning.

When not to use

Not a medical device. A licensed clinician remains responsible for interpretation.
Not a prescription. magent does not choose a vial, route, or infusion pump setting.
Not doubling-bolus titration. Loading boluses are bedside titration; this tool is the post-stabilization hourly infusion band only.
Not pralidoxime. magent does not compute oxime dose.
magent does not examine the chest or pulse and does not diagnose organophosphate poisoning.

Formula

infusion_low_mg_h = 0.10 * atropine_load_mg; infusion_high_mg_h = 0.20 * atropine_load_mg

Title: Early management after self-poisoning with an organophosphorus or carbamate pesticide – a treatment protocol for junior doctors
Authors: Eddleston M, Dawson A, Karalliedde L, Dissanayake W, Hittarage A, Azher S, Buckley NA

Worked example

18 mg atropine load

Given: atropine_load_mg=18

infusion_low_mg_h = 0.10 * 18 = 1.8 mg/h
infusion_high_mg_h = 0.20 * 18 = 3.6 mg/h

10 mg atropine load

Given: atropine_load_mg=10

infusion_low_mg_h = 0.10 * 10 = 1.0 mg/h
infusion_high_mg_h = 0.20 * 10 = 2.0 mg/h

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/atropine_op?atropine_load_mg=18"

Parameters

Name	Type	Required	Description
`atropine_load_mg`	number	required	Caller-assigned total atropine loading milligrams already used to stabilize (0.6-200). magent does not choose loading boluses.

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/atropine_op 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": [
    {
      "atropine_load_mg": "18"
    },
    {
      "atropine_load_mg": "18"
    }
  ]
}

Opens a two-item fixture on the API host. Unpaid browsers get the same MetaMask paywall as GET; Pay retries POST with those items.

Client errors (HTTP 400)

Invalid params return 400 without charge. Shared HTTP 402 and 503 meanings: Payments.

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.
