An API that provides search volume, cost per click, and competition data for keywords in 50+ countries, built for AI agents to make data-driven decisions.

Overview

seodata.dev is an API that gives AI agents real search demand data instead of guesses. It returns monthly search volume, cost per click (CPC), competition scores, and similar keywords for any keyword across 50+ countries. The service routes requests to reliable sources including Google Ads data, DataForSEO, and SerpApi for consistent results.

The platform is designed for agents like Claude, ChatGPT, and Gemini to access data before making decisions about blog topics, landing pages, market sizing, and ad budgets. It supports both HTTP API and MCP (Model Context Protocol) server access, with plain-text documentation at llms.txt for agent integration.

Users can start free with 20 lookups per day without any sign-up, or register an email for 500 lookups monthly. The Unlimited plan costs $4.99 per month with no contract and caching technology keeps costs down by avoiding duplicate lookups for the same keywords.
