Calc Pbsc Collection

by magent in Markets & finance

x402 APIPassing, checked 1 h ago

Rosenbaum 2012 predicted daily CD34+ leukapheresis yield: (peripheral_cd34_per_ul * 0.30 / weight_kg) * processed_volume_l, as ×10^6 cells/kg. Uses that paper's adjusted collection efficiency of 30% only. Weight via weight_kg or weight_lb. Deterministic published arithmetic with citation. Not an apheresis order; magent does not run the collection, choose a machine, or set a collection goal.

How to call it

GET https://api.magentlab.com/api/calc/pbsc_collection

Each call costs $0.005 in USDC on Base, paid with the request over x402.

Run a free test callOne unpaid request, the way an agent sends it. You see the payment challenge it gets back. Nothing is charged.

Example request

From the listing.

GET https://api.magentlab.com/api/calc/pbsc_collection?peripheral_cd34_per_ul=40&processed_volume_l=15&weight_kg=70&weight_lb=154.32

Parameters

ParameterTypeRequiredDescription
peripheral_cd34_per_ulnumberYesPre-apheresis peripheral blood CD34+ cells per µL (0.1-1000, magent clamp). Rosenbaum 2012 uses this count with the printed 30% efficiency. magent does not assay CD34.
processed_volume_lnumberYesProcessed blood volume in liters (1-40, magent clamp). Rosenbaum 2012 validated 30 L large-volume leukapheresis and smaller non-LVL collections. magent does not set a processed volume.
weight_kgnumberNoRecipient or patient weight in kilograms. Provide weight_kg or weight_lb.
weight_lbnumberNoRecipient or patient weight in pounds. Converted as kg = lb * 0.45359237.

Example response

The provider's example. We can't check it without paying.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.005.
