A two-sided agentic marketplace where:

• Provider side: 32 AI art tools (resize, upscale, verify provenance, generate QR, extract palette, etc.) are discoverable via MCP Streamable HTTP transport
• Consumer side: Any AI agent on Kite can discover tools, pay via x402, and receive results — no API keys needed
• Verification side: Aegis offers provenance verification as a paid service ($0.008/query) — external agents pay to verify art authenticity
• Licensing side: Training data licensing brokered through x402 — artists earn passive income when their data is licensed

Payment IS authorization. No accounts. No subscriptions. Agents pay per-call.
