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

What it computes

Apply the Hyams 2016 Rome IV H2d child/adolescent Functional Abdominal Pain NOS diagnostic criteria and return whether the published FAP-NOS box holds (rome_iv_child_fap_nos).

When to use

When an agent already has the five caller-assigned Hyams 2016 Rome IV H2d FAP-NOS flags, including the residual insufficient_criteria_for_ibs_fd_or_abdominal_migraine flag, and needs whether the published child FAP-NOS box holds. magent does not re-run IBS, functional dyspepsia, or abdominal migraine.

When not to use

• Not a medical device.
• Not a diagnosis. magent does not diagnose child FAP-NOS.
• The caller assigns the five flags, including insufficient_criteria_for_ibs_fd_or_abdominal_migraine. magent does not re-run IBS, functional dyspepsia, or abdominal migraine. magent does not examine the patient.
• This tool is Hyams 2016 Rome IV H2d Functional Abdominal Pain NOS only. Not adult CAPS (Keefer 2016). Functional abdominal pain syndrome (FAPS) was dropped in Rome IV and is not scored here.

Formula

rome_iv_child_fap_nos iff episodic_or_continuous_abdominal_pain_not_solely_during_physiologic_events and pain_at_least_4_times_per_month and insufficient_criteria_for_ibs_fd_or_abdominal_migraine and not_explained_by_another_condition and fulfilled_at_least_2_months (Hyams 2016 Rome IV H2d Functional Abdominal Pain NOS)

Call

Expect HTTP 402 until you retry with PAYMENT-SIGNATURE. Incomplete query params return HTTP 400 before any quote or charge.

curl -i -H "Accept: application/json" "https://api.magentlab.com/api/calc/rome_iv_child_fap_nos?episodic_or_continuous_abdominal_pain_not_solely_during_physiologic_events=true&pain_at_least_4_times_per_month=true&insufficient_criteria_for_ibs_fd_or_abdominal_migraine=true&not_explained_by_another_condition=true&fulfilled_at_least_2_months=true"

Parameters

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_fap_nos 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.

Client errors (HTTP 400)

Invalid params return 400 without charge. Shared HTTP 402 and 503 meanings: Payments.

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.
• Calculator inputs are stored encrypted for allowlisted operators (Magent Console). They are not in public logs, SSH lookups, catalog, or rollups. Request logs store path without query.
