KushBitx AgentProof

staging.kushbitx.com · KushBitx

Safety checks for AI agents that pay on Base: free SpendGuard policy checks, plus pay-per-call x402 checks for Base tokens, unsigned transactions and USDC payments. Also available as an MCP server at https://kushbitx.com/mcp. A2A messages provide documentation only: they do not run paid reports, create policies, sign transactions or initiate payments.
