Skavio LLC provides 18 hosted MCP tools for native Circle USDC payments via x402 v2 on Base and Solana: transaction verification, recipient/amount matching, blockchain evidence PDFs, DNS/TLS audits and agent utilities. Discovery and status tools are free; paid MCP calls require explicit buyer wallet authorization. The separate standalone Base-only HTTP APIs include USDC Verify (0.02), Match (0.03), Evidence PDF (0.05), and four DeepSeek-only web operations: Fetch (0.01), Search (0.02), Extract (0.02), Extract + Analyze (0.03 USDC). Those HTTP routes are not additional MCP tools. Evidence PDFs are not tax invoices.
