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

What it computes

Sum three caller-assigned Gorelick 2004 PASS item points and return the published 0-6 total.

When to use

When an agent has already assigned published Gorelick 2004 points for wheezing, work of breathing, and prolongation of expiration and needs the 0-6 total. magent does not auscultate or diagnose asthma.

When not to use

  • Not a medical device and not an asthma diagnosis or a treatment or admission order.
  • Each of the three items is a caller-assigned published point value from Gorelick 2004. magent does not auscultate or examine the patient.
  • Three-item PASS selected in Gorelick 2004, max 6. Score only; magent does not emit mild/moderate/severe or GINA bands.
  • Gorelick 2004 enrolled ages 1-18 years; this tool does not take an age parameter and does not validate age.
  • Not Chalut 2000 PRAM. Not hospital Pediatric Asthma Score (PAS) pathways. Not Westley 1978 croup. magent pas is Samuel 2002 pediatric appendicitis, a different score.

Formula

PASS = wheezing + work_of_breathing + prolongation_of_expiration; Gorelick 2004 caller-assigned points; each item 0/1/2; max 6

Parameters

Name Type Required Description
wheezing integer required Caller-assigned Gorelick 2004 PASS wheezing (integer 0, 1, or 2): 0 none or mild; 1 moderate; 2 severe wheezing or absent due to poor air exchange. magent does not auscultate.
work_of_breathing integer required Caller-assigned Gorelick 2004 PASS work of breathing (integer 0, 1, or 2): 0 none or mild accessory-muscle use or retractions; 1 moderate; 2 severe. magent does not examine the patient.
prolongation_of_expiration integer required Caller-assigned Gorelick 2004 PASS prolongation of expiration (integer 0, 1, or 2): 0 normal or mildly prolonged; 1 moderately prolonged; 2 severely prolonged. magent does not auscultate.

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/pass 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.

  • Westley croup — Sum the Westley 1978 croup clinical score from caller-assigned consciousness, cyanosis, stridor, air entry, and retractions (maximum 17).

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.
