Not a diagnosis, dose, or listing recommendation. ## What it computes Apply the Benninga 2016 Rome IV G1 infant regurgitation diagnostic criteria and return whether the published infant-regurgitation box holds (rome_iv_infant_regurgitation). ## When to use When an agent already has the three caller-assigned Benninga 2016 Rome IV G1 infant regurgitation flags and needs whether the published infant-regurgitation box holds. magent does not examine the infant. ## When not to use - Not a medical device. - Not a diagnosis. magent does not diagnose infant regurgitation. - The caller assigns the three flags, including the otherwise-healthy 3-weeks-to-12-months window and the exclusion list as one flag. magent does not examine the infant. - This tool is Benninga 2016 Rome IV G1 infant regurgitation only. Not GERD. Not rumination. Not child or adolescent Rome IV. ## Formula ``` rome_iv_infant_regurgitation iff otherwise_healthy_infant_3_weeks_to_12_months and regurgitation_at_least_twice_daily_for_3_or_more_weeks and no_retching_hematemesis_aspiration_apnea_ftt_feeding_swallowing_or_abnormal_posturing (Benninga 2016 Rome IV G1 infant regurgitation) ``` ## Citation [Childhood Functional Gastrointestinal Disorders: Neonate/Toddler](https://doi.org/10.1053/j.gastro.2016.02.016) Benninga MA, Faure C, Hyman PE, St James Roberts I, Schechter NL, Nurko S Gastroenterology. 2016;150(6):1443-1455 DOI: [10.1053/j.gastro.2016.02.016](https://doi.org/10.1053/j.gastro.2016.02.016) ## Worked example ### All three required flags Given: `no_retching_hematemesis_aspiration_apnea_ftt_feeding_swallowing_or_abnormal_posturing=true, otherwise_healthy_infant_3_weeks_to_12_months=true, regurgitation_at_least_twice_daily_for_3_or_more_weeks=true` 1.

The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement. Method: `POST /api/calc/rome_iv_infant_regurgitation` Max items: 25 Price: unit_amount + extra_item_amount * (n - 1) (unit 5000 atomic, extra 2000 atomic) Status: 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. Example request: ```json { "items": [ { "no_retching_hematemesis_aspiration_apnea_ftt_feeding_swallowing_or_abnormal_posturing": "true", "otherwise_healthy_infant_3_weeks_to_12_months": "true", "regurgitation_at_least_twice_daily_for_3_or_more_weeks": "true" }, { "no_retching_hematemesis_aspiration_apnea_ftt_feeding_swallowing_or_abnormal_posturing": "true", "otherwise_healthy_infant_3_weeks_to_12_months": "true", "regurgitation_at_least_twice_daily_for_3_or_more_weeks": "true" } ] } ``` Human paywall (two-item fixture): https://api.magentlab.com/paywall/bulk/rome-iv-infant-regurgitation Example 200: ```json { "count": 2, "path": "/api/calc/rome_iv_infant_regurgitation", "items": [ { "disclaimer": "Not a medical device.

Returned before settlement; you are not charged. - HTTP 400 `invalid_flag`: boolean clinical flags must be true or false Returned before settlement; you are not charged. - HTTP 400 `invalid_items`: POST body must be a JSON object with only an items array Returned before settlement; you are not charged. - HTTP 400 `invalid_item_count`: items must be an array of 1 to 25 objects Returned before settlement; you are not charged. - HTTP 400 `invalid_item`: each items entry must be a JSON object Returned before settlement; you are not charged.

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. - GET the tool with Accept: application/json (do not send Accept: text/html unless you want the human paywall). - HTTP 402 means you have not paid. Decode the base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote. - Sign accepts[0] (exact, EIP-3009) with validBefore = now + maxTimeoutSeconds (600 seconds), or accepts[1] (batch-settlement deposit/voucher) on product GET. Ping and POST {items} stay exact. Magent retries transient facilitator 429/5xx before answering. - Retry the same URL with PAYMENT-SIGNATURE (base64 JSON of accepted and payload). Magent attaches canonical extensions.bazaar on CDP verify/settle; echoing 402 bazaar is optional. - Success is HTTP 200 JSON plus PAYMENT-RESPONSE. exact settles before the tool. batch-settlement verifies (and deposit-settles) before the tool and commits the charge after HTTP 2xx. HTTP 503: retry the same PAYMENT-SIGNATURE. Mint a new exact nonce only after a new HTTP 402. - offered `exact` on eip155:8453: Fixed-price USDC on Base. The buyer authorizes the advertised amount (EIP-3009). magent settles before the tool runs (paymentFlow upfront). extra.assetTransferMethod=eip3009 extra.paymentFlow=upfront. - offered `batch-settlement` on eip155:8453: Payment-channel vouchers claimed later in batches. Exact stays accepts[0]. Same-path POST {items} is still exact. extra.assetTransferMethod=eip3009 extra.paymentFlow=authorization. - not offered `upto`: Not offered. Usage-based: buyer authorizes a ceiling, seller settles the actual amount after work. Reserved for a future metered tool. Not for current calculators or code search. Same-path POST {items} is still scheme exact: one EIP-3009 authorization for GET unit plus $0.002 per extra item. That is not x402 batch-settlement (payment channels / vouchers). Shared HTTP 402 and 503 table: https://magentlab.com/docs/payments Stdio MCP (one process per host): https://magentlab.com/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.
