## 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 wexner-constipation-score-agachan-1996-76606a44
```

Example prompt: Calculate the Wexner constipation score for a patient who has bowel movements once per week, sometimes has painful evacuation, usually has incomplete evacuation, rarely has abdominal pain, spends 10–20 minutes per attempt, uses stimulative laxatives for assistance, has 1–3 unsuccessful attempts per 24 hours, and has had constipation symptoms for 5–10 years.

## When to prefer this

Use this endpoint when you need to programmatically apply the Agachan 1996 Wexner constipation scoring system to pre-classified symptom bands, such as in clinical decision support pipelines, research data processing, or telehealth intake workflows. Prefer this over general LLM reasoning when reproducibility and exact fidelity to the published scoring table are required. Do not use for fecal incontinence scoring (Jorge 1993) or for ordering treatments.

## Known failure modes

- Missing required query parameters (frequency, painful_evacuation, incomplete_evacuation, abdominal_pain, time_per_attempt, assistance, unsuccessful_attempts, duration) returns a validation error
- Invalid enum value for any parameter returns a 400-level error
- Payment not provided or insufficient USDC balance returns a 402 Payment Required response
- Network or server timeout returns a 5xx error

## How this service works

Agachan 1996 constipation scoring system from eight caller-assigned table bands (frequency, painful evacuation, incomplete evacuation, abdominal pain, time per attempt, assistance 0-2, unsuccessful attempts per 24 hours, duration). Total 0-30. constipation true iff score > 15. magent does not take a bowel history. Not a medical device, not a laxative order, not Jorge 1993 fecal incontinence scoring.

## Output

Returns the total Wexner constipation score (integer, 0–30) computed by summing the eight Agachan 1996 band scores, plus a boolean 'constipation' field that is true when the total exceeds 15. Does not include diagnostic advice, laxative orders, or medical recommendations.
