How do I validate my OpenAI API key?

Enter your OpenAI API key (starting with sk-) in the validator form above, select OpenAI as the platform, and click 'Validate API Key'. You'll get instant results showing whether your key is valid and active.

Is it safe to use API Checkers?

Yes, absolutely! API Checkers never stores, logs, or transmits your API keys to any third party. We only make a minimal test request to verify the key's validity in real-time. Your security is our top priority.

Which AI platforms are supported?

API Checkers supports OpenAI, Anthropic, Google AI, Azure OpenAI, Perplexity, Groq, Cohere, Hugging Face, Stability AI, AWS Bedrock, Mistral, Replicate, Together AI, AI21, AssemblyAI, Deepgram, ElevenLabs, PlayHT, and more.

Is API Checkers free to use?

Yes! API Checkers is completely free to use. There are no hidden fees, no registration required, and no limitations on the number of validations.

API key validation is instant, typically taking less than 2 seconds. Our real-time validation system provides immediate feedback on whether your API key is valid and active.

Can I validate multiple API keys at once?

Currently, you can validate one API key at a time through the web interface. For bulk validation, you can use our API endpoint to programmatically validate multiple keys.

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.
