# THRIVE score THRIVE Status: LIVE Price: $0.005 USDC `GET /api/calc/thrive` HTML: https://magentlab.com/docs/thrive Markdown: https://magentlab.com/docs/thrive.md Not a medical device. Not a diagnosis, dose, or listing recommendation. ## What it computes Compute the Flint 2010 THRIVE (Totaled Health Risks in Vascular Events) score from trichotomized age, trichotomized NIHSS, and the chronic disease scale (hypertension, diabetes mellitus, atrial fibrillation). ## When to use When an agent needs the published Flint 2010 THRIVE total and 90-day good-outcome and mortality strata after endovascular stroke treatment, and must not invent NIHSS or comorbidity points from a chart narrative. ## When not to use - Not a medical device and not a treatment recommendation. - Derived in MERCI and Multi MERCI endovascular cohorts (Flint 2010). It is not a recommendation for or against endovascular therapy. - The caller assigns NIHSS and comorbidities (hypertension, diabetes mellitus, atrial fibrillation). magent does not examine the patient. ## Formula ``` THRIVE = trichotomized_age + trichotomized_nihss + CDS; age <=59 0, 60-79 1, >=80 2; NIHSS <=10 0, 11-20 2, >=21 4; hypertension, diabetes, atrial fibrillation 1 each (CDS 0-3); bands 0-2 / 3-5 / 6-9; max 9 ``` ## Citation [Predicting long-term outcome after endovascular stroke treatment: the totaled health risks in vascular events score](https://doi.org/10.3174/ajnr.A2050) Flint AC, Cullen SP, Faigeles BG, Rao VA AJNR Am J Neuroradiol. 2010;31(7):1192-1196 DOI: [10.3174/ajnr.A2050](https://doi.org/10.3174/ajnr.A2050) ## Worked example ### Age 70, NIHSS 12, hypertension only Given: `age=70, atrial_fibrillation=false, diabetes=false, hypertension=true, nihss=12` 1. Age 70 is 60-79 → 1; NIHSS 12 is 11-20 → 2; CDS hypertension only → 1 2. Score = 4 (max 9); thrive_band moderate; good outcome 43.5%; 90-day mortality 30.1% ## Also searched as - THRIVE score - Totaled Health Risks in Vascular Events - Flint THRIVE - endovascular stroke THRIVE - THRIVE NIHSS age CDS - 90-day mRS THRIVE - chronic disease scale THRIVE - Flint 2010 THRIVE ## Parameters - `age` (integer, required): Age in years (18-120). Trichotomized: ≤59 scores 0; 60-79 scores 1; ≥80 scores 2 (1 point per age level). - `nihss` (integer, required): Caller-assigned NIH Stroke Scale total (integer 0-42). Trichotomized: ≤10 scores 0; 11-20 scores 2; ≥21 scores 4 (2 points per NIHSS level). magent does not examine the patient. - `hypertension` (boolean, required): Hypertension on the chronic disease scale (CDS). true scores 1; false scores 0. - `diabetes` (boolean, required): Diabetes mellitus on the chronic disease scale (CDS). true scores 1; false scores 0. - `atrial_fibrillation` (boolean, required): Atrial fibrillation on the chronic disease scale (CDS). true scores 1; false scores 0. ## 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/thrive` 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": [ { "age": "70", "atrial_fibrillation": "false", "diabetes": "false", "hypertension": "true", "nihss": "12" }, { "age": "70", "atrial_fibrillation": "false", "diabetes": "false", "hypertension": "true", "nihss": "12" } ] } ``` Human paywall (two-item fixture): https://api.magentlab.com/paywall/bulk/thrive Example 200: ```json { "count": 2, "path": "/api/calc/thrive", "items": [ { "components": [ { "value": 70, "factor": "age", "points": 1, "present": true }, { "value": 12, "factor": "nihss", "points": 2, "present": true }, { "factor": "hypertension", "points": 1, "present": true }, { "factor": "diabetes", "points": 0, "present": false }, { "factor": "atrial_fibrillation", "points": 0, "present": false } ], "disclaimer": "Not a medical device.

Returned before settlement; you are not charged. - HTTP 400 `invalid_flag`: boolean clinical flags must be true or false Returned before settlement; you are not charged. - HTTP 400 `invalid_items`: POST body must be a JSON object with only an items array Returned before settlement; you are not charged. - HTTP 400 `invalid_item_count`: items must be an array of 1 to 25 objects Returned before settlement; you are not charged. - HTTP 400 `invalid_item`: each items entry must be a JSON object Returned before settlement; you are not charged.

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. - 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.
