What it computes

Sum five caller-assigned Qureshi 1998 Table 1 pediatric asthma-score domains (each integer 1-3) and return the published 5-15 total and mild/moderate/severe asthma_band.

When to use

When an agent has already assigned Qureshi 1998 Table 1 1-3 points for respiratory rate, oxygen saturation, auscultation, retractions, and dyspnea and needs the 5-15 total and Table 1 asthma_band. magent does not count breaths, measure SpO2, 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 five domains is a caller-assigned integer 1-3 from Qureshi 1998 Table 1. Respiratory rate is that table's age-banded 1/2/3 column, not raw breaths/min and not age. magent does not count breaths, measure SpO2, auscultate, or grade work of breathing.
Qureshi 1998 Table 1 asthma-score bands: mild 5-7, moderate 8-11, severe 12-15. Peak expiratory flow percent predicted in that table is a parallel severity path; magent does not take PEF.
Not PRAM. Not Liu 2004. Not Westley croup. Not Pediatric Appendicitis Score.

Formula

Qureshi 1998 = respiratory_rate + oxygen_saturation + auscultation + retractions + dyspnea; each caller-assigned Table 1 integer 1-3; max 15; asthma_band mild 5-7, moderate 8-11, severe 12-15

Worked example

All domains 1

Given: auscultation=1dyspnea=1oxygen_saturation=1respiratory_rate=1retractions=1

respiratory_rate 1 + oxygen_saturation 1 + auscultation 1 + retractions 1 + dyspnea 1
Score = 5 (max 15); asthma_band mild

All domains 3

Given: auscultation=3dyspnea=3oxygen_saturation=3respiratory_rate=3retractions=3

respiratory_rate 3 + oxygen_saturation 3 + auscultation 3 + retractions 3 + dyspnea 3
Score = 15 (max 15); asthma_band severe

Parameters

Name	Type	Required	Description
`respiratory_rate`	integer	required	Caller-assigned Qureshi 1998 Table 1 respiratory-rate points (integer 1-3), not raw breaths/min and not age. Table 1 age bands for 1/2/3: 2-3 yr ≤34 / 35-39 / ≥40; 4-5 yr ≤30 / 31-35 / ≥36; 6-12 yr ≤26 / 27-30 / ≥31; >12 yr ≤23 / 24-27 / ≥28. That paper enrolled ages 2-18 and has no <2 yr column. magent does not count breaths.
`oxygen_saturation`	integer	required	Caller-assigned Qureshi 1998 Table 1 oxygen-saturation points (integer 1-3): 1 if >95% on room air; 2 if 90-95% on room air or >90% with supplemental oxygen; 3 if <90% on room air or supplemental oxygen as in Table 1. magent does not measure SpO2.
`auscultation`	integer	required	Caller-assigned Qureshi 1998 Table 1 auscultation (integer 1-3): 1 normal breathing or end-expiratory wheeze; 2 expiratory wheezing; 3 inspiratory and expiratory wheezing, diminished breath sounds, or both. magent does not auscultate.
`retractions`	integer	required	Caller-assigned Qureshi 1998 Table 1 retractions (integer 1-3): 1 none or intercostal; 2 intercostal and substernal; 3 intercostal, substernal, and supraclavicular. magent does not examine the patient.
`dyspnea`	integer	required	Caller-assigned Qureshi 1998 Table 1 dyspnea (integer 1-3): 1 speaks in sentences or coos and babbles; 2 speaks in partial sentences or short cries; 3 speaks in single words, short phrases, or grunts. magent does not examine the patient.

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/pediatric_asthma_score 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.
Execution is timeout-bounded and concurrency-capped.
