APIRadar – Open-Source API Key Scanner
APIRadar is now 100% open-source with an upgraded multi-stage validation engine and live threat radar. It monitors public GitHub commits and code search for exposed credentials across 10+ providers (OpenAI, Anthropic, Google Gemini, OpenRouter, xAI, Groq, Cerebras, Slack, Discord, Telegram). Matches undergo regex filtering, static prefix stripping, Shannon Entropy scoring (H >= 2.5), and a custom trigram Markov model trained on the Google 10k English corpus to eliminate false positives.
