Keywords Everywhere

Keywords Everywhere on xpay — Keyword research and SEO metrics without the subscription

Keywords Everywhere is a keyword research and SEO analysis platform that provides search volume, cost-per-click (CPC) data, competition metrics, and related keyword suggestions. Developers and SEO teams use it to power content strategy, validate keyword opportunities, and analyze domain/URL performance at scale. On xpay, you call Keywords Everywhere's API through MCP—the Model Context Protocol—without signing up for a Keywords Everywhere account or committing to a subscription. You pay $0.01 per call, only for what you use.

What's available

• get_keyword_data — Retrieve search volume, CPC, and competition metrics for one or more keywords across different countries and currencies.
• get_related_keywords — Discover semantically related keywords based on a seed term, useful for content expansion and topic clustering.
• get_pasf_keywords — Fetch "People Also Search For" keywords (PASF) to understand user search intent and related queries.
• get_domain_keywords — See which keywords a domain ranks for, with ranking position and traffic estimates.
• get_url_keywords — Analyze keywords that a specific URL ranks for, ideal for competitive URL analysis.

When Keywords Everywhere is the right tool

• You're building a content strategy tool or SEO audit agent that needs real-time keyword metrics.
• You want to validate keyword difficulty and search intent before creating content.
• You're analyzing competitor domains or URLs to understand their ranking keywords and traffic.
• You need to discover related or "People Also Search For" keywords for topic expansion.
• You're running a multi-market SEO campaign and need localized search volume and CPC data.
• You want backlink data to inform link-building or competitive analysis workflows.

When to choose something else

• If you need deep rank tracking over time, use a dedicated rank-tracking tool like SEMrush or Ahrefs.
• If your primary need is technical SEO auditing (crawl errors, site speed, structured data), a tool like Screaming Frog or Google Search Console is more appropriate.
• If you need AI-powered content generation alongside keyword research, consider an all-in-one platform like Surfer SEO or Clearscope.
• If you're on a very tight budget and only need free keyword data, Google Keyword Planner or Ubersuggest's free tier may suffice, though data quality and volume limits apply.
• If you need real-time PPC bid data beyond CPC estimates, Google Ads API or a PPC-focused tool is more accurate.

Pricing snapshot

All 14 tools are priced at $0.01 per call. You are billed only for successful calls; no subscription, no minimum.

Quickstart

Install the Keywords Everywhere MCP endpoint in Claude Code:

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

Replace YOUR_XPAY_KEY with your xpay API key (get one free at https://xpay.tools after email or Google signup).

Once connected, you can ask Claude to call tools by their native names—for example, "Use get_keyword_data to find the search volume for 'machine learning' in the US" or "Call get_domain_keywords to see what keywords example.com ranks for." Claude will invoke the tool, and xpay will bill $0.01 per call to your account.

Alternative: Use the unified xpay endpoint to access all 14 Keywords Everywhere tools plus tools from other providers (Tavily, Apollo, etc.) through a single MCP connection:

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

With the unified endpoint, you'll use xpay_run("keywords-everywhere/<tool_name>", args) to invoke Keywords Everywhere tools alongside other providers.

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

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

Why route Keywords Everywhere through xpay?

• No Keywords Everywhere signup. xpay holds the upstream credentials; you authenticate once with your xpay API key and immediately access Keywords Everywhere's full API.
• Pay only for what you use. At $0.01 per call, you avoid monthly subscriptions and minimum commitments. A single keyword research query costs a penny.
• MCP-native integration. Keywords Everywhere is exposed as a standard MCP server, so any MCP-compatible client (Claude Code, Cursor, VS Code, Cline, etc.) can call it without custom code.
• Unified billing across providers. If you use Keywords Everywhere alongside Tavily, Apollo, or other xpay providers, all calls are billed to one xpay account with a single invoice.
• Instant access. No waiting for Keywords Everywhere approval or API key provisioning; sign up for xpay, get your key, and start making calls within seconds.
