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

## What it computes

Compute the Weiss 2007 PEDOCS two-variable score from caller-supplied waiting-room patients and total registered patients.

## When to use

When an agent has the published snapshot counts for a pediatric ED and needs the Weiss 2007 two-variable PEDOCS score, not a diversion or ambulance-bypass order.

## When not to use

- Not a medical device. Not a diversion or ambulance-bypass order.
- magent does not count patients. Caller supplies waiting-room and total registered counts. Waiting-room count cannot exceed total registered.
- Weiss 2007 reduced two-variable model for a pediatric ED. Academic NEDOCS and community CEDOCS are different tools.
- The paper's expert-consensus outcome scale is 0-200 with Likert anchors at 0 (not busy), 40 (busy), 80 (extremely busy but not overcrowded), 120 (overcrowded), 160 (severely overcrowded), and 200 (dangerously overcrowded). magent does not clamp the linear combination, does not apply a NEDOCS ≥100 overcrowding cutoff, and does not invent 20/60/100 named class bands.
- Does not apply a later bed-capacity correction. Not a diagnosis of crowding-related harm.

## Formula

```
pedocs_score = 33.3 * (0.11 + 0.07 * waiting_room_patients + 0.04 * total_registered_patients)
```

## Worked example

### Empty pediatric ED (low poles)

Given: `total_registered_patients=0, waiting_room_patients=0`

1. waiting_room_patients = 0; total_registered_patients = 0
2. pedocs_score = 33.3 * (0.11 + 0.07*0 + 0.04*0) = 33.3 * 0.11 = 3.663 → 3.7 at 1 decimal (paper 0-200 scale, unclamped)


### Busy pediatric ED snapshot (20 waiting, 50 registered)

Given: `total_registered_patients=50, waiting_room_patients=20`

1. waiting_room_patients = 20; total_registered_patients = 50
2. pedocs_score = 33.3 * (0.11 + 0.07*20 + 0.04*50) = 33.3 * 3.51, 1 decimal

## Parameters

- `waiting_room_patients` (integer, required): Patients in the waiting room (integer 0-200). Cannot exceed total_registered_patients. Weiss 2007 two-variable model. magent does not count waiting-room patients.
- `total_registered_patients` (integer, required): Total patients currently registered in the pediatric ED, including those in the waiting room (integer 0-400). Must be at least waiting_room_patients. Weiss 2007 two-variable model. magent does not count patients.

## 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.

Method: `POST /api/calc/pedocs`
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": [
    {
      "total_registered_patients": "0",
      "waiting_room_patients": "0"
    },
    {
      "total_registered_patients": "0",
      "waiting_room_patients": "0"
    }
  ]
}
```

## 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.

- 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).

## 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.
