Sponsorship
Put your product in the API responses developers and their AI agents read
ReqRes is the hosted test API developers use while writing and testing code. A sponsor's line sits inside the JSON they're working with: on their screen, and inside the AI assistants and agents that fetch it for them.

Registered developers
Live from our own servers, 26 October to 1 November. Automated and CI traffic is excluded from the developer and people counts, and each developer counts once however many responses they receive. AI agent reads count AI tools that identify themselves, so they're a floor.
What a sponsorship does
Three kinds of value, from one placement
On their screen
Developers see your line in browser tabs, API clients like Postman, terminals and the apps they're building, while they're writing code.
Inside their AI agents
ChatGPT, Claude, Cursor, Copilot and other agents read the whole response, including your line, when they fetch ReqRes for a developer.
Visits to your site
Your link goes straight to you with your own tracking. We count each developer who clicks once a day, with bots filtered out.
Options
Two ways to sponsor
Exclusive API line
Your line, labelled as sponsored, in the support field of every free API response. The text stays the same for the whole booking.
Site slot
Your logo, name and tagline in labelled sponsor units on the homepage, the docs and blog posts. Each page view shows one sponsor.

What it looks like
The API line, in a real response:
{
"page": 2,
"data": [ "...six users..." ],
"support": { "url": "https://reqres.in/go/yourcompany", "text": "Your line, up to about 140 characters.", "sponsored_by": "Your Company" }}A site unit, on the homepage, docs and blog posts:
Every sponsor gets a private, live report: developers reached, AI agent reads and visits to your site, day by day, with a CSV export.
How we run it
Clearly labelled. The API line carries sponsored_by, and every sponsor link carries rel="sponsored".
Approved before it runs. We review every line and logo. No scams, crypto pumps or adult content.
A description, never an instruction. Your line tells developers what you do. It is never written as a command to an AI agent.
Private by design. We count totals, not people: no cookies or tracking of visitors for sponsorship.
