# IV Drip Rate Calculator (gtt/min)

> IV Drip Rate Calculator (gtt/min) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Calculates intravenous gravity drip rate in drops per minute and mL/hour given volume, infusion duration, and administration set drop factor.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability iv-drip-rate-calculator-gtt-min-5bbc058a
```

Example prompt: Calculate the IV drip rate for a 1000 mL bag running over 480 minutes using a 15 gtt/mL macrodrip set — give me drops per minute and mL per hour.

## When to prefer this

Use this endpoint when you need a deterministic, cited, arithmetic IV gravity drip rate calculation (gtt/min and mL/hour) without clinical decision-making, drug dosing, or pump programming. Ideal for nursing training tools, clinical calculators, EHR integrations, or agent workflows that must verify manual gravity infusion setup against a published formula. Prefer this over general-purpose math when you want a purpose-built, auditable medical arithmetic endpoint with standardized drop factor validation (10, 15, 20, 60 gtt/mL only).

## Known failure modes

- volume_ml outside 1–10000 range — clamped or rejected
- time_min outside 1–1440 range — clamped or rejected
- drop_factor_gtt_ml not one of 10, 15, 20, or 60 — validation error
- Missing required query parameters — HTTP error response
- Non-integer drop_factor_gtt_ml — schema validation failure

## How this service works

INS gravity drip rate: gtt/min = (volume_ml × drop_factor_gtt_ml) / time_min, rounded half away from zero to an integer. Drop factor 10, 15, or 20 gtt/mL macrodrip or 60 gtt/mL microdrip. Also reports mL/hour. Not a pump program, drug order, or device. Deterministic published arithmetic with citation.

## Output

Returns the gravity drip rate as an integer in drops per minute (rounded half away from zero using the formula gtt/min = (volume_ml × drop_factor_gtt_ml) / time_min) and the equivalent flow rate in mL/hour, with a citation to the published arithmetic.
