Summary
This is a curated collection from xpay's 980+ tool marketplace, focused on content research workflows. You get about 40 tools spanning web search (Perplexity, Tavily), academic papers (Semantic Scholar), and image generation (FLUX, Ideogram, Recraft). It runs on the x402 protocol, so instead of managing API keys for each provider, you pay $0.01 per call in USDC through a single xpay account. Useful if you're building research or content workflows and want unified billing across multiple services. Connect via the streamable HTTP endpoint with your xpay API key, and your MCP client discovers all available tools automatically.
Keeps your Mac awake while Claude Code, Codex or Cursor works. Lets it sleep when they are done.

}
}
}

How It Works
- Get a key — Sign up at app.xpay.sh and add USDC credits
- Connect — Add the endpoint URL (with your key) to any MCP client
- Call tools — Your AI assistant discovers and calls tools naturally
- Auto-deduct — Each call costs $0.01 USDC, deducted from your wallet balance
No individual provider API keys. No separate accounts. One key for 30+ providers.
Requirements
- API key from app.xpay.sh
- USDC credits in your xpay wallet (add via Coinbase)
- MCP client — Claude Desktop, Cursor, Windsurf, Claude Code CLI, Cline, etc.
How x402 Works
x402 is an open protocol for machine-to-machine payments using HTTP 402 Payment Required. When a tool call requires payment:
- Server responds with
402 Payment Required+ a payment invoice - Client signs a USDC payment on Base blockchain
- Server verifies payment and executes the tool
- Settlement is instant, non-custodial, and peer-to-peer
