Finnegan

Sum Maguire 2013 Table 1 modified Finnegan items from caller-assigned exclusive cry, sleep, Moro, tremor, fever, respiratory, and stool bands plus true/false CNS, vasomotor, and GI flags. Return the 0–46 total and at_or_above_8 (true iff score ≥ 8).

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

What it computes

When to use

When an agent already has Maguire 2013 Table 1 modified FNAS observations as assigned by the caller and needs that published total and ≥8 threshold. magent does not examine the infant, score Eat Sleep Console, score Maguire's 7-item short form, or issue a morphine order.

When not to use

Not a medical device and not a diagnosis of neonatal abstinence syndrome.
magent does not examine the infant. Each item is a caller-assigned Maguire 2013 Table 1 exclusive band or true/false flag.
This is the operational modified FNAS item table reprinted as Maguire 2013 Table 1, not a 31-item website variant and not Maguire's 7-item short form.
Not Eat Sleep Console (Grossman 2018).
Not a morphine or other pharmacologic dose. at_or_above_8 is the published ≥8 suspicion / treatment threshold only. This tool does not invent mild/moderate/severe stages.

Formula

FNAS = crying + sleep + moro + tremors + increased_muscle_tone + myoclonic_jerk + generalized_convulsions + excoriation + sweating + fever + frequent_yawning + mottling + nasal_stuffiness + sneezing + nasal_flaring + respiratory + excessive_sucking + poor_feeding + regurgitation + projectile_vomiting + stools; Maguire 2013 Table 1 modified Finnegan (exclusive cry/sleep/moro/tremors/fever/respiratory/stools; remaining items true/false); max 46; at_or_above_8 iff total >= 8 (Zimmermann-Baer / Maguire suspicion and pharmacologic-treatment threshold). Not Eat Sleep Console. Not Maguire 7-item short form. magent does not examine the infant. Not a morphine order.

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/finnegan 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.

HTTP	Code	When
400	`invalid_finnegan`	Finnegan inputs must match Maguire 2013 Table 1 modified FNAS exclusive bands and true/false items from that table. Returned before settlement; you are not charged.
400	`invalid_items`	POST body must be a JSON object with only an items array Returned before settlement; you are not charged.
400	`invalid_item_count`	items must be an array of 1 to 25 objects Returned before settlement; you are not charged.
400	`invalid_item`	each items entry must be a JSON object Returned before settlement; you are not charged.

Eat, Sleep, Console — Apply the Grossman 2018 Eat, Sleep, Console functional assessment from caller-assigned eat, sleep, and console flags. magent does not examine the infant.
WAT-1 — Sum the eleven Franck 2008 WAT-1 items (ten caller-assigned 0/1 signs and time_to_calm 0-2) and return the published 0-12 total plus wat1_ge_3 (true iff score ≥3 versus NRS ≥4).

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.
