Frequently asked questions
Can I use Yurlie tools for free?
Yes. All browser-based tools (CIDR calculator, JSON formatter, Base64 encoder, etc.) are completely free and always will be. No account required.
What is the API?
The Yurlie API lets you access the same tools programmatically via HTTP requests. Send JSON, get JSON back. Useful for scripting, CI pipelines, and building your own apps.
Is my data private?
Browser tools process everything locally — your data never leaves your device. API requests are processed on our servers and are not stored or logged beyond basic rate-limit counters.
What happens if I exceed my API limit?
You'll receive a 429 Too Many Requests response with a Retry-After header. Your browser tools continue to work — limits only apply to API calls.
Can I cancel anytime?
Yes. Cancel anytime from your dashboard. You keep access until the end of your billing period. No lock-in.
