What happens if my API key is invalid?

If your API key is invalid, you'll receive a detailed error message explaining why validation failed. This helps you troubleshoot issues like expired keys, incorrect formats, or revoked credentials.

Technical Issues

Why is my validation taking longer than expected?

Validation typically takes under 2 seconds. Delays may be due to network latency or the AI platform's API response time.

My valid key shows as invalid. Why?

This could be due to expired keys, insufficient permissions, rate limiting, or the key being revoked. Double-check your key and permissions.

Currently, we support one key at a time. Batch validation may be added in future updates based on user feedback.
