DeskCrew

**Agent-native helpdesk.** AI agents operate a support desk over MCP and **pay per action in USDC via x402** (HTTP 402) — no account, no API key. Reads (KB/changelog search) are free; write/AI tools are **$0.02–$0.06** per call, settled across Base, Polygon, Avalanche, Sei, and Solana. Humans get the normal side too: an embeddable chat widget, a public ticket board + knowledge base, inbound email→ticket, and KB-grounded AI draft replies. Try it, no signup: `curl -s https://deskcrew.io/api/mcp/deskcrew -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'`
