IronLicensing SDK for Python

Software licensing and activation SDK for Python applications. Validate licenses, manage activations, check features, and handle trials.

Installation

pip install ironlicensing

Quick Start

Validate a License

import ironlicensing

# Initialize
ironlicensing.init("pk_live_xxxxx", "my-app")

# Validate a license key
result = ironlicensing.validate("IRON-XXXX-XXXX-XXXX-XXXX")

if result.valid:
    print("License is valid!")
    print(f"Expires: {result.license.expires_at}")

Activate a License

import ironlicensing

ironlicensing.init("pk_live_xxxxx", "my-app")

# Activate on this machine
result = ironlicensing.activate("IRON-XXXX-XXXX-XXXX-XXXX")

if result.valid:
    print("License activated!")
    print(f"Activations: {len(result.activations)}")

Check Features

import ironlicensing
from ironlicensing import LicenseRequiredError

ironlicensing.init("pk_live_xxxxx", "my-app")
ironlicensing.validate("IRON-XXXX-XXXX-XXXX-XXXX")

# Check if feature is enabled
if ironlicensing.has_feature("premium"):
    # Enable premium features
    pass

# Or require a feature (raises if not available)
try:
    ironlicensing.require_feature("enterprise")
    # Enterprise code here
except LicenseRequiredError:
    print("Enterprise license required")

Async Support

import asyncio
import ironlicensing

async def main():
    ironlicensing.init("pk_live_xxxxx", "my-app")

    # Async validation
    result = await ironlicensing.validate_async("IRON-XXXX-XXXX-XXXX-XXXX")

    # Async activation
    result = await ironlicensing.activate_async("IRON-XXXX-XXXX-XXXX-XXXX")

    # Async trial
    result = await ironlicensing.start_trial_async("user@example.com")

asyncio.run(main())

Using the Client Directly

from ironlicensing import LicenseClient, LicenseOptions

client = LicenseClient(LicenseOptions(
    public_key="pk_live_xxxxx",
    product_slug="my-app",
    debug=True,
))

# Validate
result = client.validate("IRON-XXXX-XXXX-XXXX-XXXX")

# Check features
if client.has_feature("premium"):
    pass

# Clean up
client.close()

Configuration

from ironlicensing import LicenseClient, LicenseOptions

client = LicenseClient(LicenseOptions(
    public_key="pk_live_xxxxx",           # Required
    product_slug="my-app",                 # Required
    api_base_url="https://api.ironlicensing.com",
    debug=False,
    enable_offline_cache=True,
    cache_validation_minutes=60,
    offline_grace_days=7,
    storage_key_prefix="ironlicensing",
))

Configuration Options

Option	Type	Default	Description
public_key	str	required	Your public key (pk_live_xxx or pk_test_xxx)
product_slug	str	required	Your product slug
api_base_url	str	https://api.ironlicensing.com	API base URL
debug	bool	False	Enable debug logging
enable_offline_cache	bool	True	Cache validation results
cache_validation_minutes	int	60	Cache validity in minutes
offline_grace_days	int	7	Offline grace period in days

License Status

LicenseStatus = Literal[
    "valid",           # License is valid
    "expired",         # License has expired
    "suspended",       # License is suspended
    "revoked",         # License is revoked
    "invalid",         # License key is invalid
    "trial",           # Trial license
    "trial_expired",   # Trial has expired
    "not_activated",   # No license activated
    "unknown",         # Unknown status
]

Features

Check Features

# Check if feature is enabled
if client.has_feature("premium"):
    enable_premium_features()

# Get feature details
feature = client.get_feature("max-users")
if feature and feature.enabled:
    print(f"Max users: {feature.metadata.get('limit')}")

# Get all features
for f in client.get_features():
    print(f"{f.name}: {'enabled' if f.enabled else 'disabled'}")

Require Features

from ironlicensing import LicenseRequiredError

try:
    client.require_feature("enterprise")
    # This code only runs if feature is available
except LicenseRequiredError:
    show_upgrade_dialog()

Trial Management

# Start a trial
result = ironlicensing.start_trial("user@example.com")

if result.valid:
    print("Trial started!")
    print(f"Expires: {result.license.expires_at}")

# Check if trial
if ironlicensing.is_trial():
    show_trial_banner(ironlicensing.get_license().expires_at)

Purchase Flow

# Get available tiers
tiers = ironlicensing.get_tiers()

for tier in tiers:
    print(f"{tier.name}: {tier.price} {tier.currency}/{tier.billing_period}")

# Start checkout
checkout = ironlicensing.start_purchase("tier-pro", "user@example.com")

if checkout.success:
    # Open checkout URL
    print(f"Checkout URL: {checkout.checkout_url}")

Deactivation

# Deactivate on this machine
if ironlicensing.deactivate():
    print("License deactivated")

License Change Events

def on_license_change(license):
    if license:
        print(f"License updated: {license.status}")
    else:
        print("License removed")

# Listen for license changes
unsubscribe = client.on_license_change(on_license_change)

# Later: unsubscribe
unsubscribe()

Offline Support

The SDK automatically caches validation results and supports offline usage:

client = LicenseClient(LicenseOptions(
    public_key="pk_live_xxxxx",
    product_slug="my-app",
    enable_offline_cache=True,
    cache_validation_minutes=60,  # Use cache for 60 minutes
    offline_grace_days=7,          # Allow 7 days offline
))

# This will use cache if available
result = client.validate()

if result.cached:
    print("Using cached validation")
