Base Conversion

The /base endpoint converts a number from one numeric base to another, anywhere between base 2 and base 36.

gethttps://api.moxon.dev/v6/base

How it works?

Digits are read as 0-9 then a-z, representing the values 0 to 35, so input is case-insensitive and the result is always lowercase. The conversion uses arbitrary-precision integers: values far beyond Number.MAX_SAFE_INTEGER keep every digit intact. A leading minus sign is preserved, except when the value is zero (-0 returns 0).

Try itget/v6/base
curl -X GET \  "https://api.moxon.dev/v6/base"
