# AIMS65 Score Calculator for Acute Upper GI Bleeding

> AIMS65 Score Calculator for Acute Upper GI Bleeding is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Calculates the Saltzman 2011 AIMS65 score (0–5) for in-hospital mortality risk stratification in acute upper gastrointestinal bleeding based on albumin, INR, mental status, systolic BP, and age.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aims65-score-calculator-for-acute-upper-gi-bleeding-b26ea09c
```

Example prompt: Calculate the AIMS65 score for a 72-year-old patient with acute upper GI bleeding: albumin 2.6 g/dL, INR 1.8, systolic BP 85 mm Hg, and altered mental status reported by the admitting nurse.

## When to prefer this

Use this endpoint when you need a fast, validated AIMS65 score computation for acute upper GI bleeding risk stratification per Saltzman 2011 criteria, especially when you need to accept albumin in either g/dL or g/L, and when you need strict boundary-value handling. Prefer this over Glasgow-Blatchford or Rockall when the caller-assigned altered mental status and albumin-based criteria are the clinical focus. Not for endoscopic or post-procedure scoring.

## Known failure modes

- Missing required parameters (age, inr, altered_mental_status, systolic_mm_hg) returns a validation error
- Providing both albumin_g_dl and albumin_g_l simultaneously returns an error
- Values outside accepted ranges (e.g. age <18, INR >10, SBP <50) may be rejected
- Payment not provided or insufficient USDC results in HTTP 402 error

## How this service works

Saltzman 2011 AIMS65 for in-hospital mortality in acute upper GI bleeding: albumin <3.0 g/dL, INR >1.5, caller-assigned altered mental status, systolic BP <=90 mm Hg, and age >65; 1 point each, max 5. Albumin 3.0, INR 1.5, and age 65 do not score; SBP 90 does. Score only; no mortality percentages. Not a diagnosis. Not Glasgow-Blatchford or Rockall. magent does not assess mental status. Albumin g/dL or g/L.

## Output

Returns a numeric AIMS65 score from 0 to 5, where each of the five criteria (albumin <3.0 g/dL, INR >1.5, altered mental status, systolic BP ≤90 mm Hg, age >65) contributes 1 point if met. No mortality percentages are provided; the score alone is returned. Boundary values (albumin exactly 3.0, INR exactly 1.5, age exactly 65) do not score; systolic BP of exactly 90 does score.
