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.
The report every sponsor gets, running live on the last 14 days of ReqRes traffic. Your name goes where "Your Company" is. Open it full size.

Registered developers
Live from our own servers, updating as you read (31 October to now). 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.
AI assistants send developers here. Microsoft Copilot and Bing's AI answers cited ReqRes 5,085 times in the 10 days to 1 November 2026, about 500 times a day. Developers who follow those answers end up calling the API that carries your line.

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.
What you get
Your product, wherever developers use ReqRes
One sponsorship puts you in front of the developers using ReqRes every day, and the AI agents working for them. You see exactly what it did, live.

A live report
A private page with developers reached, AI agent reads and visits to your site, day by day, with a CSV export.
What it looks like
Your 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" }}Your brand, 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.
