Give any agent real search demand, before it decides anything.
Stop guessing
Every agent has opinions about what people search for. seodata.dev gives it the numbers instead.
Before you write the post, check what people actually search for. Instructions are here: seodata.dev/llms.txt

Read it. The first 20 lookups need no key, so I'll start now and register if we need more.

Agents ask.
Data answers.
seodata.dev isn't another agent. It's the one thing your agent can't make up: how many people search for something, and what a click costs.

When agents guess,
data wins.
Models are confident about search demand and often wrong. Real numbers settle it.
Your agent
Guess
“Headless CMS” sounds big, so the agent plans to write “Headless CMS explained” and target the head term.
seodata.dev
Real numbers
“what is headless cms” gets 1,300 searches a month and “what is a headless cms” another 720.
Cached, so it's cheap
We cache what changes slowly, like volume and CPC, so nobody pays twice for a keyword someone already looked up. That's how unlimited costs $4.99.
One API, many sources
Every request goes to the most reliable source available, including Google Ads data, DataForSEO and SerpApi. You get one consistent response.
Made for agents
Plain-text docs at llms.txt, a remote MCP server, and a sign-up flow an agent can finish on its own. No dashboard required.
No key to start
20 lookups a day with no sign-up. Register an email for 500 a month, free. Same key when you upgrade; the limits just lift.
