Not a medical device. Not a diagnosis, dose, or listing recommendation.

What it computes

When to use

When an agent already has the five caller-assigned Hyams 2016 Rome IV H3b flags (developmental age older than 4 years, 1-month duration, defecation into places inappropriate to the sociocultural context, no evidence of fecal retention, and not explained by another condition) and needs whether the published child/adolescent nonretentive fecal incontinence box holds. magent does not examine the child.

When not to use

Not a medical device.
Not a diagnosis. magent does not diagnose child nonretentive fecal incontinence.
The caller assigns the five flags, including developmental_age_older_than_4_years and no_evidence_of_fecal_retention. magent does not examine the child.
This tool is Hyams 2016 Rome IV H3b Nonretentive Fecal Incontinence (child/adolescent, developmental age older than 4 years) only. Not H3a functional constipation. Not adult Rao 2016 F1 fecal incontinence.
Item 2 is the exclusion-of-retention flag (no_evidence_of_fecal_retention), not a symptom count. Duration is 1 month (Rome IV shortened from 2 months).

Formula

rome_iv_child_fecal_incontinence iff developmental_age_older_than_4_years and duration_at_least_1_month and defecation_into_places_inappropriate_to_sociocultural_context and no_evidence_of_fecal_retention and not_explained_by_another_condition (Hyams 2016 Rome IV H3b Nonretentive Fecal Incontinence)

Parameters

Name	Type	Required	Description

`duration_at_least_1_month`	boolean	required	At least a 1-month history (Rome IV shortened from 2 months), as assigned (Hyams 2016 Rome IV H3b). true or false as assigned by the caller. magent does not examine the child.
`defecation_into_places_inappropriate_to_sociocultural_context`	boolean	required	Defecation into places inappropriate to the sociocultural context, as assigned (Hyams 2016 Rome IV H3b item 1). true or false as assigned by the caller. magent does not examine the child.

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_child_fecal_incontinence 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.

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.
