# magent MIPI Calculator (Hoster 2008 Simplified)

> magent MIPI Calculator (Hoster 2008 Simplified) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

Computes the simplified Mantle Cell Lymphoma International Prognostic Index (MIPI) score and risk group from age, ECOG status, LDH/ULN ratio, and WBC count

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 magent-mipi-calculator-hoster-2008-simplified-2a81aeef
```

Example prompt: Calculate the simplified MIPI score for a 67-year-old MCL patient with ECOG 1, LDH/ULN ratio of 1.3, and WBC of 9,500 cells/µL — tell me the total score and whether they're low, intermediate, or high risk.

## When to prefer this

Use this endpoint when you need the Hoster 2008 four-variable simplified MIPI (not the continuous MIPI or MIPI-c) for advanced-stage mantle cell lymphoma risk stratification. Prefer this over general oncology scoring tools when the specific simplified MIPI with its three discrete risk groups (low/intermediate/high) is required for clinical documentation, trial eligibility, or treatment planning. Do not use for diagnosing MCL or when the continuous MIPI formula is required.

## Known failure modes

- Missing required parameter (age, ecog, or ldh_uln_ratio) returns validation error
- Both wbc_ul and wbc_k_ul supplied simultaneously returns error
- Age outside 18–120 range rejected
- ECOG value outside 0–4 range rejected
- LDH/ULN ratio outside 0.1–20 range rejected
- WBC value outside allowed range rejected
- Payment not provided or insufficient (x402 protocol) results in 402 response

## How this service works

Hoster 2008 simplified MIPI for advanced-stage mantle cell lymphoma: age (<50 0, 50–59 1, 60–69 2, ≥70 3), ECOG (0–1 0, 2–4 2), LDH/ULN (<0.67 0, 0.67–<1 1, 1–<1.5 2, ≥1.5 3), WBC ×10^9/L (<6.7 0, 6.7–<10 1, 10–<15 2, ≥15 3); max 11. Low 0–3, intermediate 4–5, high 6–11. Deterministic published score with citation; not a lymphoma diagnosis; not continuous MIPI; not MIPI-c. magent does not assay LDH or WBC.

## Output

Returns the total simplified MIPI score (integer 0–11), individual component subscores for age, ECOG, LDH/ULN, and WBC, and the corresponding risk classification: low (0–3), intermediate (4–5), or high (6–11), per Hoster 2008.
