Linkup API

Linkup API on xpay — Premium web search and content extraction without the signup friction

Linkup API is an AI-powered web search platform designed for agents and developers who need high-quality, sourced web results and the ability to fetch and extract content from individual pages. Unlike generic search APIs, Linkup emphasizes deep research capabilities and premium sourcing, making it a natural fit for AI workflows that demand accuracy and context. Developers typically reach for Linkup when building research assistants, fact-checking agents, or systems that need to ground LLM responses in current web data. Learn more at linkup.com.

On xpay, you connect Linkup's tools as MCP endpoints—no Linkup API account creation, no separate billing portal, no subscription lock-in. Every call is metered and billed at $0.02 per request, with transparent per-call pricing across your xpay dashboard.

What's available

• linkup_search ($0.02/call) — Query the web and retrieve AI-ranked, sourced results. Ideal for gathering current information, validating claims, or feeding context into agent reasoning.
• linkup_fetch ($0.02/call) — Retrieve and extract content from a specific URL. Use this after search to deep-dive into a promising result, extract structured data, or verify details.

When Linkup API is the right tool

• You're building a research or fact-checking agent that needs live web data.
• Your workflow requires both broad search and targeted content extraction from individual pages.
• You want premium sourcing and AI-ranked results, not just raw search engine output.
• You need to ground LLM responses in current information without hallucination risk.
• You're prototyping or running low-volume research tasks and want to avoid subscription costs.

When to choose something else

• If you only need general-purpose search and don't require premium sourcing, a lighter search API (e.g., Tavily, SerpAPI) may be more cost-effective.
• If your use case is SEO analysis, keyword research, or competitive intelligence, specialized SEO tools are better suited.
• If you need real-time stock prices, weather, or highly specialized data feeds, domain-specific APIs will be more reliable.
• If you're running millions of searches monthly, a direct Linkup contract or alternative high-volume provider may offer better rates.

Quickstart

claude mcp add --transport http linkup "https://linkup.mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"

Replace YOUR_XPAY_KEY with your xpay API key (get one free at xpay.tools after email or Google signup). Once connected, your Claude Code agent can call linkup_search and linkup_fetch by name—just ask it to search the web or fetch a page, and the MCP layer routes the request to Linkup and bills the call.

If you want to access all xpay providers (Linkup, Tavily, Apollo, etc.) through a single MCP connection, use the unified endpoint instead:

claude mcp add --transport http xpay "https://mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"

For Cursor, Windsurf, Cline, or VS Code with Copilot, add a server entry to your mcp.json file:

{
  "mcpServers": {
    "linkup": {
      "url": "https://linkup.mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"
    }
  }
}

Why route Linkup API through xpay?

• No Linkup API signup. xpay holds the upstream credentials; you authenticate once with your xpay key and gain access immediately.
• Per-call pricing with no minimums. Pay $0.02 per search or fetch—no monthly fees, no unused quota waste. Ideal for experimentation and low-volume research.
• Unified billing across providers. If you also use Tavily, Apollo, or other xpay-wrapped APIs, one dashboard, one invoice, one API key.
• MCP-native from day one. Linkup's tools are exposed as standard MCP resources; no custom wrappers or proprietary SDKs needed. Works seamlessly with Claude Code, Cursor, and any MCP-compatible agent.
• Transparent metering. Every call is logged with its cost; drill into your xpay dashboard to see exactly which tools you're using and how much each costs.
