Why It Matters
KeyProbe quickly verifies LLM API key validity and model access without requiring user accounts or storing sensitive information.
Key Features
- Validate API keys for OpenAI, Anthropic, Google, Mistral, and Groq.
- Identify which models an API key has access to.
- Compare model access across different API keys.
- Provides instant results in under 3 seconds.
Use Cases
- A developer integrating multiple LLM APIs into a new application can use KeyProbe to quickly verify that each API key is correctly configured and has the necessary model access before deploying their code.
- When troubleshooting an existing LLM-powered application that has suddenly stopped working, a support engineer can use KeyProbe to rule out invalid or expired API keys as the root cause of the issue.
- A data scientist experimenting with different LLM providers for a specific task can leverage KeyProbe to compare the model availability and access levels of various API keys without needing to sign up for multiple services.
