x402 APIPassing, checked 2 h ago

McMillan 2007 modified Glasgow Prognostic Score (mGPS) from CRP in mg/L and albumin. Elevated CRP is >10 mg/L; hypoalbuminaemia is albumin <35 g/L. mGPS 0 when CRP ≤10 (albumin ignored, including isolated hypoalbuminaemia); mGPS 1 when CRP >10 and albumin ≥35; mGPS 2 when CRP >10 and albumin <35. Not original GPS, not hs-mGPS, not a cancer diagnosis or treatment order. magent does not assay CRP or albumin.

Parameters

ParameterTypeRequiredDescription
albumin_g_dlnumberNoSerum albumin in g/dL (1-6). Converted as g/L = g/dL × 10. Provide this or albumin_g_l, not both.
albumin_g_lnumberNoSerum albumin in g/L (10-60). Provide this or albumin_g_dl, not both. McMillan 2007 hypoalbuminaemia is <35 g/L (35 is not low). Ignored when CRP ≤ 10 mg/L. magent does not assay albumin.
crp_mg_lnumberYesC-reactive protein in mg/L (0-500), not mg/dL. McMillan 2007 elevated CRP is >10 mg/L. CRP = 10 is not elevated and scores mGPS 0 regardless of albumin. magent does not assay CRP.

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.
