ParameterTypeRequiredDescription
albumin_g_dlnumberNoSerum albumin in g/dL (1-6). Provide this or albumin_g_l, not both. Greipp 2005 stages use g/dL. Stage I requires albumin >= 3.5 when Sβ2M < 3.5. Ignored when Sβ2M >= 5.5.
albumin_g_lnumberNoSerum albumin in g/L (10-60). Converted as g/dL = g/L / 10. Provide this or albumin_g_dl, not both.
beta2_microglobulin_mg_lnumberYesSerum beta-2 microglobulin in mg/L (0.2-40). Greipp 2005 Sβ2M. Stage I requires < 3.5; stage III when >= 5.5. magent does not assay beta-2 microglobulin.

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.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.magentlab.com/api/calc/myeloma_iss?albumin_g_dl=4&albumin_g_l=40&beta2_microglobulin_mg_l=2'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
