# AIMS65 AIMS65 Status: LIVE Price: $0.005 USDC `GET /api/calc/aims65` HTML: https://magentlab.com/docs/aims65 Markdown: https://magentlab.com/docs/aims65.md Not a medical device. Not a diagnosis, dose, or listing recommendation. ## What it computes Compute the Saltzman 2011 AIMS65 score for in-hospital mortality in acute upper GI bleeding from albumin, INR, caller-assigned altered mental status, systolic blood pressure, and age. ## When to use When an agent needs the published AIMS65 total and must not invent Glasgow-Blatchford, Rockall, or mortality percentages. ## When not to use - Not a diagnosis. magent does not diagnose the cause or severity of bleeding. - Not Glasgow-Blatchford and not Rockall. This tool is the Saltzman 2011 AIMS65 score only. - magent does not assess mental status. altered_mental_status is a caller-assigned flag. - Albumin <3.0 g/dL, INR >1.5, and age >65 are strict inequalities: albumin 3.0, INR 1.5, and age 65 do not score. Systolic BP ≤90 mm Hg includes 90. ## Formula ``` AIMS65 = (albumin_g_dl<3.0) + (inr>1.5) + altered_mental_status + (systolic_mm_hg<=90) + (age>65); each 1 if present; max 5 ``` ## Citation [A simple risk score accurately predicts in-hospital mortality, length of stay, and cost in acute upper GI bleeding](https://doi.org/10.1016/j.gie.2011.06.024) Saltzman JR, Tabak YP, Hyett BH, Sun X, Travis AC, Johannes RS Gastrointest Endosc. 2011;74(6):1215-1224 DOI: [10.1016/j.gie.2011.06.024](https://doi.org/10.1016/j.gie.2011.06.024) ## Worked example ### All criteria absent Given: `age=50, albumin_g_dl=4.0, altered_mental_status=false, inr=1.0, systolic_mm_hg=120` 1. Albumin 4.0 is not <3.0 → 0; INR 1.0 is not >1.5 → 0; mental status false → 0; SBP 120 is not ≤90 → 0; age 50 is not >65 → 0 2. Score = 0 (max 5) ### All five criteria present Given: `age=66, albumin_g_dl=2.5, altered_mental_status=true, inr=1.6, systolic_mm_hg=90` 1. Albumin 2.5 < 3.0 → 1; INR 1.6 > 1.5 → 1; mental status true → 1; SBP 90 ≤ 90 → 1; age 66 > 65 → 1 2. Score = 5 (max 5) ## Also searched as - AIMS65 score - AIMS-65 - Saltzman AIMS65 - upper GI bleed score - acute UGIB AIMS65 - AIMS 65 ## Parameters - `age` (integer, required): Age in years (18-120). Scores 1 when age >65; 65 does not score. - `albumin_g_dl` (number, optional): Albumin in g/dL (1-6). Provide this or albumin_g_l, not both. Scores 1 when <3.0; 3.0 does not score. - `albumin_g_l` (number, optional): Albumin in g/L (10-60). Converted as g/dL = g/L / 10. Provide this or albumin_g_dl, not both. - `inr` (number, required): INR (0.8-10). Scores 1 when >1.5; 1.5 does not score. - `altered_mental_status` (boolean, required): Altered mental status as assigned by the caller. true or false. magent does not assess mental status. 1 point if true. - `systolic_mm_hg` (number, required): Cuff systolic blood pressure in mm Hg (50-250). Scores 1 when ≤90; 90 scores. ## Bulk (POST) POST the same path with a JSON items array. Price is n times the GET unit. Invalid items return HTTP 400 before settlement. Method: `POST /api/calc/aims65` Max items: 25 Price: unit_amount * n (unit 5000 atomic) Status: PREVIEW - 1 to 25 items. Each item uses the same keys as the GET query parameters. - 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": "50", "albumin_g_dl": "4.0", "altered_mental_status": "false", "inr": "1.0", "systolic_mm_hg": "120" }, { "age": "50", "albumin_g_dl": "4.0", "altered_mental_status": "false", "inr": "1.0", "systolic_mm_hg": "120" } ] } ``` Human paywall (two-item fixture): https://api.magentlab.com/paywall/bulk/aims65 Example 200: ```json { "count": 2, "path": "/api/calc/aims65", "items": [ { "components": [ { "value": 4.0, "factor": "albumin_lt_3", "points": 0, "present": false }, { "value": 1.0, "factor": "inr_gt_1_5", "points": 0, "present": false }, { "factor": "altered_mental_status", "points": 0, "present": false }, { "value": 120.0, "factor": "systolic_mm_hg_le_90", "points": 0, "present": false }, { "value": 50, "factor": "age_gt_65", "points": 0, "present": false } ], "disclaimer": "Not a medical device.

Returned before settlement; you are not charged. - HTTP 400 `invalid_age`: age must be an integer from 18 to 120 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. Shared HTTP 402 and 503: https://magentlab.com/docs/payments ## Related tools - [Glasgow-Blatchford score](https://magentlab.com/docs/glasgow-blatchford) — Compute the Blatchford 2000 Glasgow-Blatchford score from urea, haemoglobin, systolic BP, heart rate, and four clinical flags. ## Payment Required query parameters must be present and valid. 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 EIP-3009 (scheme exact, assetTransferMethod eip3009) with validBefore = now + accepts[0].maxTimeoutSeconds (600 seconds). That window starts when you sign and must cover wallet confirmation plus CDP verify and settle. Magent retries transient facilitator 429/5xx before answering. Do not send upto or batch-settlement payloads; magent does not offer those schemes. - Retry the same URL with PAYMENT-SIGNATURE (base64 JSON echoing accepted, payload, and extensions when present). - Success is HTTP 200 JSON plus PAYMENT-RESPONSE. Settlement happens before the tool runs. HTTP 503 settlement_uncertain or settle_failed: retry the same PAYMENT-SIGNATURE. Mint a new 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. - 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. - not offered `batch-settlement`: Not offered. Payment-channel vouchers claimed later in batches. Not the same as POST {items} bulk (that is still exact). Same-path POST {items} is still scheme exact: one EIP-3009 authorization for n times the GET unit. 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 - Invalid query parameters return HTTP 400 before settlement. You are not charged. - Settlement finishes before the tool executes (paymentFlow upfront). 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.
