# Paradise recurrent throat infection Paradise Status: LIVE Price: $0.005 USDC `GET /api/calc/paradise` HTML: https://magentlab.com/docs/paradise Markdown: https://magentlab.com/docs/paradise.md Not a medical device. Not a diagnosis, dose, or listing recommendation. ## What it computes Apply the Paradise 1984 eligibility frequency for recurrent throat infection and return whether paradise_criteria holds (frequency met and qualifying episode features). ## When to use When an agent already has caller-assigned Paradise 1984 frequency flags and whether counting episodes had the trial's published qualifying features, and needs whether the published eligibility box holds. magent does not examine the patient or count episodes. ## When not to use - Not a medical device. - Not a tonsillectomy order. magent does not decide whether to operate. - The caller assigns frequency flags and qualifying episode features. magent does not examine the patient or count episodes. - Paradise 1984 eligibility frequency only. Not AAO-HNS 2019 as a separate guideline tool. ## Formula ``` paradise_criteria iff qualifying_episode_features and (ge_7_episodes_preceding_year or ge_5_episodes_each_of_2_years or ge_3_episodes_each_of_3_years) (Paradise 1984 eligibility frequency for recurrent throat infection) ``` ## Citation [Efficacy of tonsillectomy for recurrent throat infection in severely affected children.

The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement. Method: `POST /api/calc/paradise` 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": [ { "ge_3_episodes_each_of_3_years": "false", "ge_5_episodes_each_of_2_years": "false", "ge_7_episodes_preceding_year": "true", "qualifying_episode_features": "true" }, { "ge_3_episodes_each_of_3_years": "false", "ge_5_episodes_each_of_2_years": "false", "ge_7_episodes_preceding_year": "true", "qualifying_episode_features": "true" } ] } ``` Human paywall (two-item fixture): https://api.magentlab.com/paywall/bulk/paradise Example 200: ```json { "count": 2, "path": "/api/calc/paradise", "items": [ { "disclaimer": "Not a medical device.

Shared HTTP 402 and 503: https://magentlab.com/docs/payments ## Related tools - [Centor and McIsaac scores](https://magentlab.com/docs/centor) — Compute the Centor score or the McIsaac age-modified score from four caller-assigned pharyngitis findings.

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.
