# magent Fomepizole Dosing Calculator

> magent Fomepizole Dosing Calculator 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 adult IV fomepizole doses (mg) for ethylene glycol or methanol poisoning based on patient weight and hemodialysis status, following AACT 1999 protocol.

## Facts

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 magent-fomepizole-dosing-calculator-8fbdced8
```

Example prompt: Calculate the fomepizole dose for a 75 kg adult patient who is NOT on hemodialysis — I need the loading dose and the maintenance schedule.

## When to prefer this

Use this endpoint when you need a fast, protocol-accurate fomepizole dose calculation per AACT 1999 guidelines for adult patients, especially in emergency or critical care workflows where weight-based mg dosing and hemodialysis schedule adjustments must be computed quickly and reliably. Prefer this over manual calculation to reduce arithmetic errors in high-stakes clinical settings.

## Known failure modes

- Weight outside the 1–200 kg valid range returns an error or unexpected result
- Missing required 'hemodialysis' boolean parameter causes a validation error
- Incorrect data type for weight_kg (e.g. string instead of number) causes a schema validation error
- Network timeout or service unavailability returns a non-200 HTTP status

## How this service works

Adult IV fomepizole milligrams from weight (AACT 1999). Loading 15 mg/kg. Maintenance 10 mg/kg every 12 hours for four doses, then 15 mg/kg every 12 hours after 48 hours (auto-induction). Same milligrams during hemodialysis at a 4-hour interval. Not a prescription, indication, or brand order. magent does not assay ethylene glycol or methanol.

## Output

Returns the calculated fomepizole doses in milligrams for the given patient weight: loading dose (15 mg/kg), maintenance doses (10 mg/kg every 12 hours for four doses, then 15 mg/kg every 12 hours after 48 hours due to auto-induction), and during hemodialysis the same milligram doses at 4-hour intervals.
