Client configuration

Configuration reference

LicenseClient accepts these constructor options; no developer API key is needed.

Option	Type / default	Meaning
product	str, required	Public App ID
environment	str, "production"	LIVE default; SANDBOX for testing; TEST/PRODUCTION aliases
base_url	str, https://licensing.kdpika.com	HTTPS origin only, no path/query/user info
application_name	str, "Licensed Application"	App label and default state-path component
application_version	str, ""	Your app version sent on activation
verification_key	dict[str,str] or None	Optional authorized key_id/public_key pin; Ed25519/base64url
storage_dir	pathlib.Path or None	Private persistent root; SDK adds namespace
timeout	float, 15.0	Per-request socket timeout, >0 and <=120; not a total wall-time guarantee
prefer_keyring	bool, True	Try optional usable native keyring
transport	private Transport or None	Advanced trusted injection; preserve wire JSON with HttpResponse.from_bytes
clock	callable returning aware datetime or None	UTC clock by default; injection for tests
allow_loopback_http	bool, False	Keyword-only explicit local HTTP testing, never remote HTTP

Pins never rotate automatically. Ordinary clients fetch the current key only from their configured authenticated HTTPS origin. No envelope-supplied key is trusted.
