# Naloxone Drip Rate Calculator (Goldfrank 1986)

> Naloxone Drip Rate Calculator (Goldfrank 1986) 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 continuous IV naloxone infusion rate as two-thirds of the caller-supplied reversal bolus dose per hour, per the Goldfrank 1986 protocol.

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 naloxone-drip-rate-calculator-goldfrank-1986-d21d5dd7
```

Example prompt: I just used a 0.8 mg naloxone bolus to reverse an opioid overdose — what should the continuous IV infusion rate be using the Goldfrank two-thirds rule?

## When to prefer this

Use this endpoint when you need to programmatically apply the Goldfrank 1986 two-thirds rule for naloxone maintenance infusion and already have a clinician-assigned reversal bolus dose. Prefer this over manual calculation when integrating dosing support into a clinical decision-support pipeline or agent workflow that needs a reproducible, formula-based result.

## Known failure modes

- Missing reversal_bolus_mg parameter returns a validation error
- reversal_bolus_mg outside the 0.04–10.0 mg range may be rejected or flagged
- Non-numeric input for reversal_bolus_mg causes a schema validation failure
- Payment failure (x402 protocol) results in 402 response without computation

## How this service works

Continuous intravenous naloxone infusion as two-thirds of the caller-assigned reversal bolus each hour (Goldfrank 1986). infusion_mg_h = (2/3) * reversal_bolus_mg maintains plasma naloxone at or above the 30-minute post-bolus level. magent does not choose the bolus or start naloxone. Not a prescription or medical device.

## Output

Returns the calculated continuous IV naloxone infusion rate in mg/hour, computed as (2/3) × reversal_bolus_mg, intended to maintain plasma naloxone at or above the 30-minute post-bolus level per the Goldfrank 1986 protocol.
