Our #3 traffic source, every single week
All figures measured from our own analytics and database, July 2026. We share the raw dashboards with serious sponsors.
Why this audience is different
You are not buying pageviews. You are buying adjacency to the answer.
ReqRes has been the default "free API for testing" since 2014, embedded in a decade of tutorials, courses, and Stack Overflow answers. That corpus is what large language models trained on. The result: when a developer asks an AI assistant for a test API, ReqRes is the recommendation.
We can measure it. chatgpt.com is our #3 traffic source every week, ahead of Bing. ChatGPT fetches reqres.in live 300 to 450 times a day to answer user questions. Referrer-based numbers undercount this channel, since most AI tools strip referrers, so the true share is higher than what we can show.
No newsletter or podcast can sell you this placement. It only exists where the models already point.
Who you reach
QA and test engineers, at work, mid-task
Around 90% of developers who tell us their role are in QA and testing, with the remainder split between frontend developers and educators. They arrive with a job to do: wire up a test suite, demo an integration, teach an API class. High intent, tool-buying roles.
Geography is India-first, US second, with the long tail across Southeast Asia, Eastern Europe, and LATAM. If your growth motion includes the Indian developer market, this audience is a direct line into it. We are upfront about this because the sponsors it fits, it fits extremely well.
Discovery is organic: 54,000 search impressions and 4,000+ clicks a week at a 7.7% click-through rate, on queries like "free api for testing" and "dummy api".

The rules we won't break
Sponsorship never touches the API
The API responses stay deterministic and sponsor-free, forever. That reliability is why a decade of tutorials and the AI models built on them keep recommending ReqRes, and it is exactly what makes the audience worth reaching. We will not trade the asset for a placement.
One sponsor per product category, clearly labeled as sponsorship, with monthly reporting from the same dashboards we run the business on.
