# Gorelick 2004 Pediatric Asthma Severity Score (PASS) Calculator

> Gorelick 2004 Pediatric Asthma Severity Score (PASS) 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).

Computes the Gorelick 2004 three-item Pediatric Asthma Severity Score (PASS) by summing caller-assigned wheezing, work of breathing, and prolongation of expiration scores (0–2 each, max 6).

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 gorelick-2004-pediatric-asthma-severity-score-pass-calculator-4ce387ba
```

Example prompt: Calculate the Gorelick 2004 PASS score for a child with moderate wheezing (1), severe work of breathing (2), and moderately prolonged expiration (1).

## When to prefer this

Use this endpoint when you need a pure, reproducible Gorelick 2004 PASS numeric sum for a pediatric asthma patient and all three component scores have already been assessed by a clinician. Prefer this over narrative or AI-generated severity estimates when auditability and fidelity to the published instrument are required. Do not use if you need the Chalut 2000 PRAM, Westley 1978 croup score, or a hospital-specific PAS variant.

## Known failure modes

- Missing required parameter (wheezing, work_of_breathing, or prolongation_of_expiration) returns an error
- Non-integer or out-of-range values (outside 0, 1, 2) for any component return a validation error
- Incorrect query parameter names cause a bad request error
- Payment failure or missing x402 header results in 402 Payment Required

## How this service works

Gorelick 2004 three-item Pediatric Asthma Severity Score (PASS): caller-assigned wheezing (0 none or mild; 1 moderate; 2 severe or absent from poor air exchange), work_of_breathing (0 none or mild; 1 moderate; 2 severe), and prolongation_of_expiration (0 normal or mildly prolonged; 1 moderately; 2 severely). magent sums only (max 6) and does not auscultate. Score only; no invented severity or GINA bands. Not a diagnosis, not Chalut 2000 PRAM, not Westley 1978 croup, and not hospital PAS.

## Output

Returns the integer PASS total score (0–6) computed by summing the three caller-supplied component scores. No severity band labels, GINA classifications, or diagnostic interpretations are added — just the numeric sum.
