Returns a boolean rome_iv_child_abdominal_migraine field (true/false) indicating whether all Rome IV H2c criteria are met, plus a numeric count (0–6) of how many of the six associated features (anorexia, nausea, vomiting, headache, photophobia, pallor) were positive.

Example use cases
Pediatric GI chart review automation
“I'm reviewing a 10-year-old with recurrent abdominal pain. Episodes are paroxysmal, intense, periumbilical, last about 90 minutes, occur every few weeks, are incapacitating, follow a stereotypical pattern, and the child has nausea and pallor during episodes. Not explained by another diagnosis, and this has been going on for 8 months. Can you run the Rome IV abdominal migraine score?”
Clinical research eligibility screening
“For our study, I need to check if this patient meets Rome IV H2c criteria: paroxysmal intense diffuse pain lasting over 1 hour, episodes months apart, pain is incapacitating, stereotypical, with anorexia and headache as associated features, no alternative explanation, and fulfilled for 7 months — does she qualify?”
Telemedicine pre-visit triage
“A parent is reporting their child has had recurrent midline belly pain for 9 months, each episode lasts more than an hour, happens a few times a year, is completely incapacitating with a consistent pattern, and the child gets pale and nauseated during attacks, no other diagnosis has been found. Please calculate the Rome IV abdominal migraine criteria count.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rome_iv_child_abdominal_migraineWhen to prefer
Use this endpoint when you need to programmatically evaluate whether a child meets Rome IV H2c criteria for abdominal migraine using caller-supplied clinical observations. Prefer this over general symptom checkers when you specifically need Hyams 2016 Rome IV scoring with a discrete boolean result and associated feature count. Do not use for adult migraine scoring, cyclic vomiting syndrome, or non-pediatric GI criteria.
Side effects
- Missing required boolean query parameters returns a validation error
- Non-boolean values for flag parameters cause a 400 bad request
- Payment failure (x402) if USDC balance is insufficient or payment header is missing
- Misinterpretation of criteria by caller (endpoint only scores what is passed — it does not examine the patient)
