What it computes

Apply the Benninga 2016 Rome IV G4 infant colic clinical criteria and return whether the published clinical box holds (rome_iv_infant_colic).

When to use

When an agent already has the three caller-assigned Benninga 2016 Rome IV G4 clinical flags and needs whether the published infant colic box holds. magent does not examine the infant.

When not to use

Not a medical device.
Not a diagnosis. magent does not diagnose infant colic.
The caller assigns the three flags. magent does not examine the infant.
This tool is Benninga 2016 Rome IV G4 infant colic clinical criteria only. Research 3-hour/diary criteria are not parsed.

Parameters

Name	Type	Required	Description
`infant_less_than_5_months_when_symptoms_start_and_stop`	boolean	required	An infant who is less than 5 months of age when the symptoms start and stop, as assigned (Benninga 2016 Rome IV G4). true or false as assigned by the caller. magent does not examine the infant.
`recurrent_prolonged_crying_fussing_or_irritability_without_obvious_cause`	boolean	required	Recurrent and prolonged periods of infant crying, fussing, or irritability reported by caregivers that occur without obvious cause and cannot be prevented or resolved by caregivers, as assigned (Benninga 2016 Rome IV G4). true or false as assigned by the caller. magent does not examine the infant.
`no_failure_to_thrive_fever_or_illness`	boolean	required	No evidence of infant failure to thrive, fever, or illness, as assigned (Benninga 2016 Rome IV G4). true or false as assigned by the caller. magent does not examine the infant.

Bulk (POST)

POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement.

POST /api/calc/rome_iv_infant_colic Max 25 unit_amount + extra_item_amount * (n - 1) extra $0.002 PREVIEW

1 to 25 items. Each item uses the same keys as the GET query parameters.
POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows.
The first invalid item fails the whole request (index in the 400 JSON). You are not charged.
HTTP 200 is {count, path, items}. Each items[i] is the GET 200 body for that row.
Catalog misses (empty matches, found=false) stay paid 200s inside that slot.
x402 resource URL is this path plus n and body_sha256. Browsers that prefer text/html get the same paywall as GET; Pay retries POST with the same items.

  "items": [
    {
      "infant_less_than_5_months_when_symptoms_start_and_stop": "true",

Payment

Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, invalid params return HTTP 400 JSON before settlement. magent does not charge. Fix the params, then request a new 402 quote for that complete URL. Catalog misses (empty matches, found=false) are valid paid 200s. Unpaid valid requests return HTTP 402 with a base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote: retry the same PAYMENT-SIGNATURE. Full handshake and shared payment errors: Payments. Stdio MCP: /docs/mcp.

Guarantees

HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged. HTTP 402 never includes the tool JSON.
exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. Uncertain or failed settlement fails closed (HTTP 503). Retry the same PAYMENT-SIGNATURE.
HTTP 402 is unpaid only. Do not sign a second authorization because of a 503.
Execution is timeout-bounded and concurrency-capped.
