Frequently Asked Questions
Common questions about API key validation
How does the validation work?
We make a minimal test request to the provider's API to verify your key is valid and active. The request uses the least expensive endpoint available and doesn't consume your credits significantly.
Do you store my API keys?
Absolutely not. Your API keys are never stored, logged, or transmitted to any third-party services. They exist only in memory during the validation process and are immediately discarded.
Is this service free?
Yes, 100% free with no limits. No registration required, no hidden fees, and no premium tiers. We believe API key validation should be accessible to everyone.
How long does validation take?
Most validations complete in under 2 seconds. The exact time depends on the platform's API response time and your network connection.
What if my key is invalid?
You'll receive a clear error message explaining why the key is invalid. Common reasons include expired keys, incorrect format, insufficient permissions, or revoked access.
Can I validate multiple keys at once?
Currently, we support one key at a time to ensure accuracy and security. Batch validation may be added in future updates.
