RelayShield Security Intelligence
Gives Claude direct access to RelayShield's security intelligence APIs through seven tools: breach lookups across 13 billion records via HIBP, live SIM swap detection from carrier data, typosquat domain monitoring using certificate transparency, OAuth supply chain breach checks for apps like Slack and GitHub, and async URL/file malware scanning across 70+ engines. Runs on either a RapidAPI subscription (free tier: 100 calls/month, paid from $29/month) or pure pay-as-you-go via USDC on Base using the x402 protocol at $0.10 to $0.50 per check. Useful when you need security checks inline with AI workflows without building integrations yourself.
