What it computes

Compute neonatal glucose infusion rate in mg/kg/min from dextrose concentration and infusion rate using the unit conversion used with the 2011 AAP postnatal glucose homeostasis report.

When to use

When an agent already has dextrose percent and either ml/h plus weight or ml/kg/h and must not order dextrose, TPN, or treat GIR as a glucose prescription.

When not to use

• Not a medical device. Not a glucose or TPN prescription. magent does not order dextrose.
• GIR = (dextrose_percent × rate_ml_h) / (6 × weight_kg), or (dextrose_percent × rate_ml_kg_h) / 6. Provide rate_ml_h with weight_kg, or rate_ml_kg_h, not both rate styles.
• dextrose_percent 2.5-25, weight_kg 0.4-10, rate_ml_h 0.5-200, and rate_ml_kg_h 0.5-20 are magent clamps; they are not AAP 2011 input bands.
• AAP 2011 describes intravenous D10W at 5 to 8 mg/kg per minute (80 to 100 mL/kg per day) for persistent hypoglycemia. magent reports gir_mg_kg_min only and does not classify that treatment range or order fluids.
• Caller supplies dextrose concentration and infusion rate. magent does not assay plasma glucose.

Formula

gir_mg_kg_min = (dextrose_percent × rate_ml_h) / (6 × weight_kg); equivalently (dextrose_percent × rate_ml_kg_h) / 6

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/gir?dextrose_percent=10&rate_ml_h=7.5&weight_kg=3"

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/gir 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)

      "rate_ml_h": "7.5",

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.
• 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.
