# Pediatric Trauma Score (PTS) Calculator — Tepas 1987

> Pediatric Trauma Score (PTS) Calculator — Tepas 1987 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 Pediatric Trauma Score (Tepas 1987) from six caller-assigned clinical items and flags whether the score is ≤8 (threshold associated with significant mortality and trauma-center care).

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 pediatric-trauma-score-pts-calculator-tepas-1987-377a2710
```

Example prompt: Calculate the Pediatric Trauma Score for a child weighing 15 kg, with a normal airway, systolic BP of 95 mm Hg, who is awake, has no skeletal injury, and has a minor wound — and tell me if the score is ≤8.

## When to prefer this

Use this endpoint when you need a deterministic, published Pediatric Trauma Score per Tepas 1987 — specifically the six-item (weight, airway, systolic BP, CNS, skeletal, wound) formula with −6 to +12 range and the clinically significant ≤8 flag. Prefer this over ISS or RTS calculators when the patient is pediatric and you need this specific validated instrument. Not a replacement for clinical examination or triage orders.

## Known failure modes

- Missing required query parameters (airway, systolic_mm_hg, cns, skeletal, wound) → validation error
- Neither weight_kg nor weight_lb provided → missing required size item error
- Out-of-range values (e.g. systolic_mm_hg > 300, weight_kg < 1) → validation rejection
- Invalid enum string for airway/cns/skeletal/wound → rejection with allowed values listed
- Network or service unavailability → HTTP 5xx error

## How this service works

Pediatric Trauma Score from Tepas 1987: six caller-assigned items (weight, airway, systolic BP, CNS, skeletal, wound), each +2 / +1 / −1, total −6 to +12 (higher is better). Returns score_le_8 because scores ≤8 were associated with significant mortality and trauma-center care. Deterministic published arithmetic with citation; not ISS or RTS; not a triage order. magent does not examine the child.

## Output

Returns the total Pediatric Trauma Score (integer from −6 to +12, higher is better) derived from the six Tepas 1987 items, plus a boolean score_le_8 flag indicating whether the score falls at or below 8 — the published threshold associated with significant mortality and need for trauma-center care.
