  "markdown": "# xpay MCP Server\n\n980+ AI tools available as MCP servers. Pay $0.01/call in USDC via the [x402 protocol](https://x402.org). One API key, 30+ providers — no individual provider accounts or subscriptions needed.\n\n## Quick Start\n\n### 1. Get your API key\n\nSign up at [app.xpay.sh](https://app.xpay.sh) and create an API key. Add credits to your wallet (USDC on Base).\n\n### 2. Add to your MCP client\n\n**Claude Desktop / Cursor / Windsurf** — add to your MCP config:\n\n```json\n{\n  \"mcpServers\": {\n    \"xpay\": {\n      \"url\": \"https://mcp.xpay.sh/mcp?key=YOUR_API_KEY\"\n    }\n  }\n}\n```\n\n**Claude Code CLI:**\n\n```bash\nclaude mcp add --transport http \"xpay\" \"https://mcp.xpay.sh/mcp?key=YOUR_API_KEY\"\n```\n\nReplace `YOUR_API_KEY` with your key from step 1.\n\n### 3. Use tools\n\nYour AI assistant will automatically discover all available tools. Each tool call costs $0.01 USDC, deducted from your wallet balance.\n\n## Collection Servers\n\nInstead of connecting to all 980+ tools, you can connect to a focused collection:\n\n| Collection | Endpoint | Tools | Providers |\n|---|---|---|---|\n| **All Tools** | `https://mcp.xpay.sh/mcp?key=YOUR_API_KEY` | 980+ | All 30+ |\n| **Lead Generation** | `https://lead-gen.mcp.xpay.sh/mcp?key=YOUR_API_KEY` | ~50 | Hunter, Apollo, Tomba, Sixtyfour, Fiber, Exa, Nyne |\n| **Competitive Intel** | `https://compete.mcp.xpay.sh/mcp?key=YOUR_API_KEY` | ~40 | Brand.dev, Coresignal, Keywords Everywhere, Exa, Firecrawl, Shofo |\n| **Content Research** | `https://content.mcp.xpay.sh/mcp?key=YOUR_API_KEY` | ~40 | Perplexity, Tavily, Semantic Scholar, FLUX, Ideogram, Recraft |\n| **Web Scraping** | `https://scraping.mcp.xpay.sh/mcp?key=YOUR_API_KEY` | ~35 | Firecrawl, Bright Data, Jina, Olostep, ScrapeGraph, Notte |\n| **Developer Tools** | `https://devtools.mcp.xpay.sh/mcp?key=YOUR_API_KEY` | ~30 | Context7, Code Runner, Python Execute, NPM Sentinel, PlantUML |\n| **Finance** | `https://finance.mcp.xpay.sh/mcp?key=YOUR_API_KEY` | 253 | Financial Modeling Prep, Alpha Vantage, AkShare, Polymarket |\n| **Media Studio** | `https://media.mcp.xpay.sh/mcp?key=YOUR_API_KEY` | ~25 | FLUX, Ideogram, Recraft, Stability AI, MiniMax, Kokoro |\n| **Social Media** | `https://social.mcp.xpay.sh/mcp?key=YOUR_API_KEY` | 96 | ScapeCreators, Shofo, YouTube |\n| **Academic Research** | `https://research.mcp.xpay.sh/mcp?key=YOUR_API_KEY` | ~30 | Semantic Scholar, Google Scholar, PubMed, arXiv |\n| **Marketing** | `https://marketing.mcp.xpay.sh/mcp?key=YOUR_API_KEY` | ~30 | Keywords Everywhere, Brand.dev, Exa, Tavily, Ideogram |\n\n## How It Works\n\n1. **Get a key** — Sign up at [app.xpay.sh](https://app.xpay.sh) and add USDC credits\n2. **Connect** — Add the endpoint URL (with your key) to any MCP client\n3. **Call tools** — Your AI assistant discovers and calls tools naturally\n4. **Auto-deduct** — Each call costs $0.01 USDC, deducted from your wallet balance\n\nNo individual provider API keys. No separate accounts. One key for 30+ providers.\n\n## Requirements\n\n- **API key** from [app.xpay.sh](https://app.xpay.sh)\n- **USDC credits** in your xpay wallet ([add via Coinbase](https://www.coinbase.com))\n- **MCP client** — Claude Desktop, Cursor, Windsurf, Claude Code CLI, Cline, etc.\n\n## How x402 Works\n\n[x402](https://x402.org) is an open protocol for machine-to-machine payments using HTTP 402 Payment Required. When a tool call requires payment:\n\n1. Server responds with `402 Payment Required` + a payment invoice\n2. Client signs a USDC payment on Base blockchain\n3. Server verifies payment and executes the tool\n4. Settlement is instant, non-custodial, and peer-to-peer\n\n## Browse Tools\n\n- **Hub**: [xpay.tools](https://xpay.tools)\n- **Docs**: [docs.xpay.sh](https://docs.xpay.sh)\n- **Platform**: [xpay.sh](https://xpay.sh)\n\n## Related\n\n- [`@xpaysh/x402`](https://www.npmjs.com/package/@xpaysh/x402) — x402 facilitator SDK\n- [`@xpaysh/n8n-nodes-xpay`](https://www.npmjs.com/package/@xpaysh/n8n-nodes-xpay) — n8n community node\n- [`@xpaysh/agent-kit-langchain`](https://www.npmjs.com/package/@xpaysh/agent-kit-langchain) — LangChain integration\n- [xpay Facilitator](https://facilitator.xpay.sh) — Open x402 facilitator service\n\n## License\n\nMIT\n",
