GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
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.

Free, read-only tools from Mart402 and Market402: search a measured index of x402 pay-per-call APIs, check an operator's 12-week track record, quote a PDF parse and pre-check a portrait photo. Nothing here charges or asks for payment.
Pay-per-call APIs built for AI agents: crypto market data, onchain checks, x402 tools, and the web and documents (web search, page fetch and extract, screenshots, PDF to text, an HTTP proxy, x402 marketplace search and pre-pay quotes). No API keys, no signup. Agents pay per call via x402 in USDC on Base.
