YOUR API DIAGNOSTICS WORKSPACE

AI API Key Checker.
One key. A clear answer.

Check your Azure, AWS Bedrock, OpenAI, Claude, and Gemini keys.
Inspect the information each provider makes available.

01 Inspect a key

Key format is detected automatically.

Select your provider manually if the format is ambiguous.

Your credentials pass through this hosting server to the selected provider over HTTPS. This application saves no key history and sends no Telegram notifications.

PROVIDER-SPECIFIC DIAGNOSTICS

API key checks that explain the response.

Use AI API Key Checker to diagnose credentials you own, review access errors, and understand exactly what a provider returns.

Azure OpenAI key checker

Pair your Azure API key with its resource endpoint to query the model catalog. Review HTTP status and the returned models. Resource restrictions and deployment permissions can affect access.

Check an Azure key ↗

AWS Bedrock key checker

Choose Bedrock bearer authentication or AWS IAM credentials with SigV4 signing. Select a supported region, or use AWS STS to inspect the account ID and caller identity.

Check AWS credentials ↗

OpenAI API key checker

Recognize project and service-account key formats and inspect the models endpoint. Admin keys have their own project-listing check. Catalog access does not establish a credit balance.

Check an OpenAI key ↗

Claude API key checker

Check Anthropic authentication against the Claude models API. Inspect the raw response and any available request identifiers, organization details, or rate-limit headers.

Check a Claude key ↗

Google Gemini key checker

Inspect Gemini models with AIza or AQ. key formats, using an authentication header. Account restrictions, a disabled API, or quota limits may require separate configuration.

Check a Gemini key ↗

More API providers

Inspect OpenRouter key usage, Hugging Face identity, Tavily limits, ElevenLabs subscription data, and other supported services. Available information depends on each endpoint.

API key checker FAQ

What does an API key checker verify?

It sends a provider-specific request and shows the returned HTTP status, response data, and diagnostic headers. A successful catalog request does not prove every model permission or available credit.

Can I check an Azure key or AWS Bedrock credentials?

Yes. Azure requires its resource endpoint. AWS Bedrock supports bearer API keys or signed IAM credentials with a regional endpoint. Temporary AWS credentials also require a session token.

Are API keys stored by AI API Key Checker?

AI API Key Checker keeps entered credentials in memory during the check. It does not save key history. Exports redact entered keys, AWS secrets, and session tokens, but may contain account information returned by the provider.

Does checking a key consume API credits?

Catalog, account, and identity checks use read-only endpoints. Perplexity and NVIDIA checks generate a short response only when explicitly enabled and may incur provider charges. Generation requests are never retried.
