# Miller 2013 ATLAS Score Calculator for Clostridioides difficile

> Miller 2013 ATLAS Score Calculator for Clostridioides difficile is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Computes the ATLAS score (0–10) and predicted CDI cure percentage using Miller 2013 criteria based on age, systemic antibiotics, WBC, albumin, and creatinine.

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 miller-2013-atlas-score-calculator-for-clostridioides-difficile-4a15fe0a
```

Example prompt: Calculate the Miller 2013 ATLAS score for a 72-year-old CDI patient who is on systemic antibiotics, has a WBC of 18,000/µL, albumin of 30 g/L, and creatinine of 140 µmol/L.

## When to prefer this

Use this endpoint when you need a rapid, standardized ATLAS score for a patient with confirmed or suspected Clostridioides difficile infection to estimate likelihood of cure with CDI therapy; it is not a CDI diagnostic tool, stool culture, or antibiotic prescribing service.

## Known failure modes

- Missing required fields (age or systemic_antibiotics) returns a validation error
- Providing both wbc_ul and wbc_k_ul simultaneously causes an error
- Providing both albumin_g_l and albumin_g_dl simultaneously causes an error
- Providing both creatinine_umol_l and creatinine_mg_dl simultaneously causes an error
- Out-of-range values (e.g. age <18 or >120) return a validation error
- Payment failure or missing x402 payment header causes a 402 response

## How this service works

Miller 2013 ATLAS for Clostridioides difficile: age (<60 0, 60–79 1, ≥80 2), systemic antibiotics during CDI therapy (0 or 2), WBC (<16 0, 16–25 1, >25 ×10^9/L 2), albumin (>35 0, 26–35 1, ≤25 g/L 2), creatinine (≤120 0, 121–179 1, ≥180 µmol/L 2); max 10. Predicted cure percent = 100 − 5.08 × score (1 decimal). Not a CDI diagnosis, stool culture, or metronidazole/vancomycin/fidaxomicin order.

## Output

Returns the integer ATLAS total score (0–10) and the predicted cure percentage (to 1 decimal place, computed as 100 − 5.08 × score), derived from the five Miller 2013 ATLAS criteria.
