Get a free key

50 lookups a day and 500 a month, free. You don't fill in a form: your agent signs you up, or your assistant does when it connects.

Ask your agent

Paste this into Claude Code, Cursor, ChatGPT or any agent that can make web requests.

Read https://seodata.dev/llms.txt and register a free seodata.dev API key for me with my email. Ask me for the 6-digit code from the email, then save the key so you can use it for keyword research.

  1. 1
    Your agent registers your email.
  2. 2
    You read it the 6-digit code from your inbox.
  3. 3
    It saves the key and starts looking things up.

Connect with MCP

Add our server to Claude, ChatGPT or Muse. The first time it needs data, it opens a sign-in page and your key is created for you.

https://mcp.seodata.dev/mcp
  1. 1
    Add the server URL to your assistant.
  2. 2
    Sign in with your email and a 6-digit code.
  3. 3
    Ask for keyword data in plain language.
