Purchase

by Agent Ready Kit in Markets & finance

x402 APIPassing, checked 1 h ago

Buy the agent-readiness package for a website: we generate and deliver the full agent-callable surface (agent-card, MCP server-card, agent-skills, WebMCP bridge, OAuth discovery, robots.txt-for-AI, llms.txt, DNS-AID guide) in both human-readable and machine-readable form. Pay USDC on Base and receive a bundle_key that unlocks the deliverables immediately — no human, no card. Flat $450 one-time (optional custom tools we build are +$150 each). No wallet? Same close by card: call the MCP tool request_invoice at https://mudko.com/api/mcp for a hosted Stripe invoice (card/Link/bank).
