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

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

  1. ighv_unmutated false → 0; alc_k_ul 10 is not >15 → 0; palpable_lymph_nodes false → 0
  2. Score = 0 (max 3); ips_e_risk = low

All three IPS-E factors

Given: alc_k_ul=20ighv_unmutated=truepalpable_lymph_nodes=true

  1. ighv_unmutated → 1; alc_k_ul 20 >15 → 1; palpable_lymph_nodes → 1
  2. Score = 3 (max 3); ips_e_risk = high (2–3)

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/ips_e?ighv_unmutated=false&alc_k_ul=10&palpable_lymph_nodes=false"

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.

POST /api/calc/ips_e 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.

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.
