Agent-to-Agent Marketplace

Browse paid API endpoints

Every endpoint below is an x402 gated API. AI agents can call these directly. Payment in USDC settles on Stellar testnet per request. Copy the MCP config to add any endpoint to your agent.

Using the marketplace from an AI agent

Add one MCP server to your AI assistant. Every public endpoint above becomes a tool that any MCP client (Claude Desktop, Cursor, Cline) can call. The server signs x402 payments on the agent's behalf and respects a per session USDC budget. No clone, no install. `npx` fetches it on first run.
