What it computes
Sum the 2020 IPS-E (international prognostic score for asymptomatic early-stage chronic lymphocytic leukemia) and return low (0), intermediate (1), or high (2–3).
When to use
When an agent needs the published IPS-E point total and risk band for early-stage asymptomatic CLL and must not invent a treatment start order, and must not substitute CLL-IPI, Rai, or Binet.
When not to use
- Not a medical device and not a CLL diagnosis or treatment start order. magent does not examine the patient.
- This is Condoluci 2020 IPS-E (time to first treatment in early-stage asymptomatic CLL), not CLL-IPI, not Rai, and not Binet.
- magent does not assay IGHV, count lymphocytes, or palpate lymph nodes. ighv_unmutated and palpable_lymph_nodes are caller-assigned flags; alc_k_ul is caller-supplied ALC.
Formula
IPS-E = ighv_unmutated 1 + alc_gt_15 1 + palpable_lymph_nodes 1; Condoluci 2020; max 3; low 0, intermediate 1, high 2-3

Worked example
No IPS-E factors
Given:
alc_k_ul=10ighv_unmutated=falsepalpable_lymph_nodes=false
- ighv_unmutated false → 0; alc_k_ul 10 is not >15 → 0; palpable_lymph_nodes false → 0
- Score = 0 (max 3); ips_e_risk = low
All three IPS-E factors
Given:
alc_k_ul=20ighv_unmutated=truepalpable_lymph_nodes=true
- ighv_unmutated → 1; alc_k_ul 20 >15 → 1; palpable_lymph_nodes → 1
- Score = 3 (max 3); ips_e_risk = high (2–3)

Parameters
| Name | Type | Required | Description |
|---|---|---|---|
ighv_unmutated |
boolean | required | Unmutated IGHV as assigned by the caller (Condoluci 2020 IPS-E). true scores 1. magent does not sequence IGHV. |
alc_k_ul |
number | required | Absolute lymphocyte count in ×10^9/L (0.1-500). >15 scores 1 (Condoluci 2020 IPS-E). 15.0 is the ≤15 arm and scores 0. magent does not count lymphocytes. |
palpable_lymph_nodes |
boolean | required | Palpable lymph nodes as assigned by the caller (Condoluci 2020 IPS-E). true scores 1. magent does not palpate lymph nodes. |
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.
- 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.

- 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.
- 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).
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.
