SEOdata.dev

SEOdata.dev is an API for pulling live SEO data into your own code, starting with keyword metrics like monthly search volume, cost-per-click, and competition. Instead of logging into a dashboard and exporting spreadsheets, you make an HTTP request and get structured numbers back. It aggregates data from established providers behind the scenes, so you hit one consistent endpoint rather than juggling separate accounts and formats from each source.

The core call is about as plain as an API gets. You send a GET request to the keyword endpoint with a search term and a two-letter country code, and it returns the search volume, CPC, and competition score for that term in that market. It covers more than fifty countries using standard ISO codes, which means the same request shape works whether you're checking demand in the United States, Germany, or Brazil. The response is built for programmatic use, so it slots straight into a script, a spreadsheet function, or a product feature without any scraping or cleanup.

Those three numbers each answer a different question. Search volume tells you how many people look for a term in a month, which is the raw demand signal. CPC hints at how much advertisers are willing to pay for a click on it, a decent proxy for commercial intent. Competition scores how crowded the paid landscape is. Together they let you sort a messy list of ideas into the ones worth chasing and the ones that are either too quiet or too contested to bother with, and you get that judgment programmatically instead of eyeballing a dashboard.

The reason a developer reaches for something like this is that raw keyword data is usually locked behind heavy, expensive SEO suites that are priced and shaped for marketers clicking around a UI. If all you want is the search volume for a list of terms so you can rank them, feed a content planner, or show demand data inside your own tool, those suites are overkill and their exports fight you. SEOdata.dev strips the offering down to the data itself and hands it to you over a clean interface you can call from anywhere.

Getting started is low-ceremony. You can hit the keyword endpoint anonymously for a small daily allowance with no signup at all, which is enough to test whether the data fits your use case before committing to anything. Registration is a lightweight email step, where you post an email address and confirm with a six-digit code sent to your inbox, and from there you get an API key that works as a standard bearer token on authenticated requests. There's even an llms.txt file published, a nod to the fact that a lot of the people wiring this in are doing it through AI coding assistants that read that file to learn the API.

It fits indie developers, builders, and small teams who want SEO data as an ingredient rather than a destination. Think a niche keyword tool, a content-planning app, a dashboard that shows clients their search demand, or an internal script that scores hundreds of terms overnight. Anyone who has tried to bolt keyword data onto a side project and run headfirst into enterprise pricing is squarely the target here, because the whole design assumes you're writing code, not booking a sales demo.

What makes it different is the deliberate narrowness and the pricing to match. Big platforms bundle rank tracking, site audits, backlink explorers, and reporting into one seat, and you pay for all of it whether you use it or not. SEOdata.dev does one job, serves it over an API, and prices it for individual builders. The roadmap points at filling out the picture with SERP results, showing the top ten organic rankings with their titles, URLs, and descriptions, plus domain analysis for estimated traffic and backlink counts, but the shipped product today is squarely the keyword data. That focus means the numbers you get back are the ones a keyword-research workflow actually starts from, and the pieces on the way extend the same API surface rather than pushing you into a separate dashboard to use them.

On pricing, it's freemium and cheap. The anonymous tier gives you twenty requests a day with no account, a free registered account raises that to five hundred requests a month, and the premium plan removes the limit for about five dollars a month. That puts unlimited keyword lookups within reach of a hobby project, which is unusual in a category where four-figure annual plans are the norm. For a lot of builders, that price gap is the entire reason to choose it over the incumbents. And because the free registered tier is generous enough for light real use, plenty of small projects never end up needing to pay at all.
