# magent I-SEE EoE Severity Score Calculator

> magent I-SEE EoE Severity Score Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

Computes the Dellon 2022 I-SEE (Index of Severity for Eosinophilic Esophagitis) composite score and severity band from caller-supplied clinical parameters

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-i-see-eoe-severity-score-calculator-aa65f45d
```

Example prompt: Calculate the I-SEE score for a patient with daily symptoms, no food impaction, no hospitalizations or perforations, no malnutrition, no persistent inflammation, mild inflammatory endoscopy (grade 1), peak eos between 15 and 60, endoscope passes easily through strictures (passes_easily), and mild histologic fibrosis — what severity band does that come out to?

## When to prefer this

Use this endpoint when you have all required Dellon 2022 Table I inputs already extracted from clinical notes or structured EHR data and need a validated, reproducible I-SEE score with severity band. It is not a substitute for endoscopy or eosinophil counting — callers must supply those values. Prefer this over manual calculation to eliminate arithmetic errors in the weighted composite score.

## Known failure modes

- Missing required query parameter returns validation error
- Invalid enum value for any parameter (e.g. unrecognized symptoms or fibro_endoscopy token) returns 400
- Network timeout or service unavailability returns 5xx
- Caller supplies clinically inconsistent values (e.g. child food impaction token for an adult) — magent scores as provided without clinical validation
- Peak eos value must be caller-assigned; magent cannot derive it from raw counts

## How this service works

Dellon 2022 I-SEE Table I: symptoms 0/1/2/4, food_impaction 0/2/4, stacking complications (hospitalization 4, perforation 15, malnutrition 15, persistent_inflammation 15), inflam endoscopy 0-2, peak eos 0-2, fibro endoscopy 0/1/2/15, histologic fibrosis 2. Max 78. Bands <1 inactive, 1-6 mild, 7-14 moderate, ≥15 severe. magent does not perform endoscopy or count eos. Not EREFS. Not a diagnosis.

## Output

Returns the numeric I-SEE total score (0–78) along with the severity band classification: inactive (<1), mild (1–6), moderate (7–14), or severe (≥15), based on weighted contributions from symptoms, food impaction, complications, inflammatory endoscopy, peak eosinophils, fibrostenotic endoscopy, and histologic fibrosis as defined in Dellon 2022 Table I.
