Binet 1981 CLL staging

Binet

Apply Binet 1981 chronic lymphocytic leukemia staging and return stage A, B, or C from caller-assigned anemia (Hb <10 g/dL), thrombocytopenia (platelets <100×10^9/L), and involved lymphoid areas (0-5).

Not a medical device. Not a diagnosis, dose, or listing recommendation.

What it computes

Apply Binet 1981 chronic lymphocytic leukemia staging and return stage A, B, or C from caller-assigned anemia (Hb <10 g/dL), thrombocytopenia (platelets <100×10^9/L), and involved lymphoid areas (0-5).

When to use

When an agent already has CLL with lymphocytosis and caller-assigned anemia, thrombocytopenia, and Binet five-area count, and needs the published Binet 1981 stage. magent does not diagnose CLL and does not examine the patient.

When not to use

  • Not a medical device.
  • Not a CLL diagnosis. The caller already has CLL with lymphocytosis; magent does not diagnose CLL.
  • magent does not examine the patient or count lymph-node areas. The caller assigns the five-area count after Binet's uni/bilateral rule (cervical, axillary, inguinal — uni or bilateral counts as one area each — plus spleen, plus liver).
  • This tool is Binet 1981 staging only. Not Rai staging (Rai anemia is Hb <11), not modified Rai, and not CLL-IPI. No A/B/C substages and no survival months.

Formula

Binet C if anemia_hb_lt_10 or thrombocytopenia_plt_lt_100; else B if involved_areas >= 3; else A (involved_areas 0-2) (Binet 1981)

Worked example

One involved area, no cytopenia

Given: anemia_hb_lt_10=falseinvolved_areas=1thrombocytopenia_plt_lt_100=false

  1. anemia_hb_lt_10 is false and thrombocytopenia_plt_lt_100 is false
  2. involved_areas is 1, which is not >= 3

Expect HTTP 402 until you retry with PAYMENT-SIGNATURE. Incomplete query params return HTTP 400 before any quote or charge.

curl -i -H "Accept: application/json" "https://api.magentlab.com/api/calc/binet?anemia_hb_lt_10=false&thrombocytopenia_plt_lt_100=false&involved_areas=1"

Parameters

Name Type Required Description
anemia_hb_lt_10 boolean required Hb <10 g/dL as assigned by the caller (Binet 1981 stage C cutoff is 10 g/dL, not Rai 11). true or false. magent does not assay hemoglobin.
thrombocytopenia_plt_lt_100 boolean required Platelets <100×10^9/L as assigned by the caller (Binet 1981 stage C). true or false. magent does not count platelets.
involved_areas integer required Count of involved Binet lymphoid areas (integer 0-5) as assigned by the caller after Binet 1981: cervical, axillary, and inguinal (unilateral or bilateral counts as one area each), plus spleen, plus liver. magent does not examine the patient or count lymph-node areas.

Bulk (POST)

POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement.

POST /api/calc/binet Max 25 unit_amount + extra_item_amount * (n - 1) extra $0.002 PREVIEW

  • 1 to 25 items. Each item uses the same keys as the GET query parameters.
  • POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows.
  • 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.

400 invalid_binet anemia_hb_lt_10 and thrombocytopenia_plt_lt_100 must be true or false (Binet 1981). Returned before settlement; you are not charged.
400 invalid_involved_areas involved_areas must be an integer from 0 to 5 (Binet 1981 five lymphoid areas). Returned before settlement; you are not charged.
400 invalid_items POST body must be a JSON object with only an items array Returned before settlement; you are not charged.
400 invalid_item_count items must be an array of 1 to 25 objects Returned before settlement; you are not charged.
400 invalid_item each items entry must be a JSON object Returned before settlement; you are not charged.

Related tools

  • CLL-IPI — Sum the 2016 CLL-IPI (chronic lymphocytic leukaemia international prognostic index) and return low (0–1), intermediate (2–3), high (4–6), or very_high (7–10).
  • Rai — Apply Rai 1975 original clinical staging of chronic lymphocytic leukemia and return rai_stage 0-4 from four caller-assigned flags.

Payment

Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, 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. Unpaid valid requests return HTTP 402 with a base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote: retry the same PAYMENT-SIGNATURE. Full handshake and shared payment errors: Payments. Stdio MCP: /docs/mcp.

Guarantees

  • HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged. HTTP 402 never includes the tool JSON.
  • exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. 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.
