## 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-scoff-eating-disorder-screen-27304878
```

Example prompt: Score this patient's SCOFF questionnaire: they said yes to making themselves sick, yes to feeling food dominates their life, no to losing more than a stone in 3 months, no to believing they're fat when others say they're thin, and yes to having lost control over eating — is the screen positive?

## When to prefer this

Use this endpoint when you need a deterministic, cited implementation of the Morgan 1999 SCOFF questionnaire score computed server-side without having to implement the scoring logic yourself. Prefer it over general LLM scoring when auditability and a published citation are required, or when embedding SCOFF into a clinical decision-support or intake workflow where reproducibility matters.

## Known failure modes

- Missing one or more of the five required boolean query parameters returns a validation error
- Non-boolean values for flag parameters cause a request rejection
- Network timeout on the API endpoint
- Payment failure (x402 protocol) prevents execution

## How this service works

Morgan 1999 SCOFF questionnaire: five caller-assigned yes/no flags (make yourself sick, lost control over eating, lost more than one stone / 14 lb in 3 months, believe fat when others say thin, food dominates life), 1 point each, max 5. Screen-positive when two or more answers are affirmative (score ≥2). Deterministic published score with citation; not a diagnosis of an eating disorder and not a medical device. magent does not interview the patient or interpret individual items.

## Output

Returns a numeric SCOFF score from 0 to 5 (one point per affirmative answer) and a screen-positive boolean or indicator when the score is 2 or greater, based on the published Morgan 1999 threshold. The result is deterministic and cited; it is not a diagnosis.
