What is Keyword Research X402?

Keyword Research X402 is an MCP server that provides SEO keyword research via Google Suggest with intent scoring and long-tail discovery. It operates on a pay-per-call basis using the x402 protocol (USDC on Base L2), requiring no API key or signup. It is part of the klymax402 marketplace of 100 x402 micropayment APIs for AI agents.

How to use Keyword Research X402?

Add the server URL to your MCP client configuration (e.g., Claude Desktop, Cursor, ElizaOS) as shown in the README. For direct HTTP access, use any x402-aware client to call the API endpoint; the server returns a 402 payment challenge that the client automatically handles.

常见问题

How do I pay for API calls?

Payment is handled via the x402 protocol using USDC on Base L2 (network `eip155:8453`). The server issues a 402 payment challenge; an x402-aware client (such as `@x402/fetch` or `x402-agent-tools`) automatically signs and retries the request.

Do I need an API key or sign up?

No. The service requires no API key, no signup, and no account – simply pay per call through x402.

What data does the `seo_research_keywords` tool return?

It returns Google autocomplete suggestions, related queries (with modifiers like "vs", "for", "how to", "best", "what is"), long-tail keywords, and search intent classification (informational, transactional, or navigational).

Are there rate limits?

There are no rate limits. Each call costs $0.01, so usage is limited only by your wallet balance.

What transports and authentication does the server support?

The server supports MCP (via a URL endpoint) and plain HTTP. Authentication is handled automatically by the x402 payment protocol – no manual tokens or keys required.
