## 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 rome-iv-g1-infant-regurgitation-calculator-benninga-2016-c870cbb2
```

Example prompt: Using the Rome IV G1 Benninga 2016 criteria, check if an otherwise healthy 4-month-old infant qualifies as functional infant regurgitation — the baby has been spitting up at least twice a day for the past 4 weeks and has no retching, hematemesis, aspiration, apnea, failure to thrive, feeding difficulties, or abnormal posturing.

## When to prefer this

Use this endpoint when you need a fast, auditable computation of the Benninga 2016 Rome IV G1 infant regurgitation criteria specifically for infants aged 3 weeks to 12 months. Prefer it over general clinical NLP or LLM reasoning when you need a deterministic, citable criterion check. Do not use for GERD evaluation, Rome IV criteria for children/adolescents, or rumination disorder screening.

## Known failure modes

- Missing required query parameters returns an error — all three boolean flags are required
- Misapplication to infants outside the 3-week to 12-month age range yields an incorrect result (caller is responsible for age assignment)
- Applying to children or adolescents is out of scope and will produce meaningless results
- Network or payment (x402) failure returns no result

## How this service works

Benninga 2016 Rome IV G1 infant regurgitation. rome_iv_infant_regurgitation is true iff otherwise_healthy_infant_3_weeks_to_12_months, regurgitation_at_least_twice_daily_for_3_or_more_weeks, and no_retching_hematemesis_aspiration_apnea_ftt_feeding_swallowing_or_abnormal_posturing. magent does not examine the infant. Not a diagnosis, not GERD, not rumination, not child or adolescent Rome IV.

## Output

Returns a boolean field rome_iv_infant_regurgitation indicating whether all three Rome IV G1 criteria are met: the infant is otherwise healthy and aged 3 weeks to 12 months, regurgitation occurs at least twice daily for 3 or more weeks, and no alarm features (retching, hematemesis, aspiration, apnea, failure to thrive, feeding/swallowing difficulties, or abnormal posturing) are present. This is not a clinical diagnosis, not GERD, not rumination, and does not apply to children or adolescents.
