# Binet 1981 CLL Staging Calculator

> Binet 1981 CLL Staging Calculator 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 Binet 1981 chronic lymphocytic leukemia (CLL) stage (A, B, or C) from caller-supplied anemia status, thrombocytopenia status, and number of involved lymphoid areas.

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 binet-1981-cll-staging-calculator-8c954482
```

Example prompt: Use the Binet 1981 CLL staging calculator: the patient does NOT have anemia (Hb is not below 10) and does NOT have thrombocytopenia, and has 4 involved Binet lymphoid areas — what stage are they?

## When to prefer this

Use this endpoint when you need to programmatically apply the Binet 1981 CLL staging system specifically — noting its Hb <10 g/dL anemia cutoff (not the Rai <11 cutoff). Prefer this over manual lookup when automating oncology workflows, building CLL dashboards, or integrating staging into EHR pipelines.

## Known failure modes

- Missing required query parameters (anemia_hb_lt_10, thrombocytopenia_plt_lt_100, or involved_areas) returns a validation error
- involved_areas outside the integer range 0–5 may produce an error or undefined behavior
- Boolean parameters passed as non-boolean strings may fail schema validation
- Payment not provided or insufficient USDC results in HTTP 402 payment required

## How this service works

Binet 1981 CLL staging. Stage C if anemia (Hb <10 g/dL) or thrombocytopenia (platelets <100×10^9/L), regardless of lymphoid areas. Else stage B when involved_areas is 3-5, else stage A when 0-2. The five areas are cervical, axillary, and inguinal (unilateral or bilateral counts as one area each), plus spleen, plus liver; the caller assigns the count. Not a medical device, not a CLL diagnosis, and not Rai staging (Rai anemia is Hb <11).

## Output

Returns the Binet 1981 CLL stage as A, B, or C: Stage C if anemia (Hb <10) or thrombocytopenia (platelets <100×10^9/L) regardless of lymphoid area count; Stage B if involved areas are 3–5 without the above; Stage A if involved areas are 0–2 without the above.
