# magent NEWS Score Calculator (RCP 2012)

> magent NEWS Score Calculator (RCP 2012) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Calculates the National Early Warning Score (NEWS, RCP 2012 Chart 1) from six vital signs and AVPU, returning a 0–20 total, Chart 2 clinical risk tier, and red-score flag.

## Facts

- Endpoint: GET https://api.magentlab.com/api/calc/news
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/magent-news-score-calculator-rcp-2012-dfaf4146
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_QJUACZcpF8B7aZ6gqilto

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-news-score-calculator-rcp-2012-dfaf4146
```

Example prompt: Calculate the NEWS score for a patient with respiratory rate 22, SpO2 94%, no supplemental oxygen, temperature 38.5°C, systolic BP 105 mmHg, heart rate 112 bpm, and AVPU of alert — what's the total score and clinical risk level?

## When to prefer this

Choose this endpoint when you need a deterministic, citeable RCP 2012 NEWS (not NEWS2) score from seven discrete vital sign inputs with Chart 2 risk classification. Prefer it over manual lookup tables when automating triage pipelines, EHR integrations, or remote monitoring alerts where reproducibility and a published arithmetic standard matter. Do not use for ICU admission orders, NEWS2 SpO2 Scale 2 logic, or GCS-based consciousness scoring.

## Known failure modes

- Missing any of the seven required query parameters returns a validation error
- Out-of-range values (e.g. SpO2 outside 50–100, temperature outside 30–45) may be rejected
- AVPU value not matching the enum (alert/voice/pain/unresponsive) returns an error
- Payment failure or missing x402 header results in a 402 Payment Required response
- Does not accept NEWS2 Scale 2 SpO2 logic or Fahrenheit temperatures — caller must convert

## How this service works

NEWS from RCP 2012 Chart 1: respiratory rate, SpO2, supplemental oxygen, temperature (°C), systolic BP, heart rate, and caller-assigned AVPU (alert 0; voice, pain, or unresponsive 3 each) summed to a 0–20 total. Returns Chart 2 clinical_risk (low/medium/high) and red_score when any parameter scores 3. Deterministic published arithmetic with citation; not NEWS2; not an ICU-admission order.

## Output

Returns the summed NEWS total (0–20), the Chart 2 clinical risk band (low, medium, or high), and a red_score flag that is set when any single parameter scores 3, indicating a high-acuity concern per the RCP 2012 protocol.
