# magent SCORMA Calculator

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

Computes the Heide 2001 SCORMA (SCORing MAstocytosis) integer score from caller-supplied skin extent, four intensity signs, and five symptom ratings

## 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-scorma-calculator-758e2273
```

Example prompt: Calculate the SCORMA score for a mastocytosis patient: skin extent 30%, pigmentation 2, vesiculation 1, elevation/induration 1, Darier's sign 2, flushing 5, provocation factors 3, diarrhoea 2, bone pain 1, pruritus 4.

## When to prefer this

Use this endpoint when you need a deterministic, formula-based SCORMA severity score for mastocytosis and already have all ten caller-assigned clinical values (skin extent, four intensity signs, five symptoms). It does not examine the patient, assign signs, or interpret results diagnostically — it only computes the arithmetic. Prefer it over manual calculation to avoid formula errors in clinical research or EHR automation pipelines.

## Known failure modes

- Missing required query parameters returns an error — all ten parameters are mandatory
- Out-of-range values (e.g. extent_percent > 100 or intensity sign > 3) will be rejected or produce schema validation errors
- Payment failure (x402) if USDC balance is insufficient
- No clinical interpretation is provided — score only, no diagnosis or WHO/ICC/REMA mapping

## How this service works

Heide 2001 SCORMA: extent_percent/5 + 5*intensity_sum + 2*symptom_sum/5. Extent 0-100 (diffuse cutaneous mastocytosis is 100). Four intensity signs 0-3 (pigmentation, vesiculation, elevation/induration, Darier's sign). Five symptoms 0-10 (flushing, provocation factors, diarrhoea, bone pain, pruritus). Max 100. magent does not examine the skin. Not a diagnosis, WHO/ICC criteria, REMA, or tryptase.

## Output

Returns the computed SCORMA integer score (maximum 100) derived from the Heide 2001 formula: extent_percent/5 + 5×intensity_sum + 2×symptom_sum/5, where intensity_sum is the sum of four skin signs (0–3 each) and symptom_sum is the sum of five symptom ratings (0–10 each).
