how to automatically verify cors policies across your endpoints without manual checks

the problem

managing cors policies across multiple services can be a pain. it's easy to miss misconfigurations or inconsistencies, which can expose your app to security risks or cause cross-origin errors.

the solution

our api cross-origin-resource-policymapper automatically fetches and analyzes cors headers from your endpoints. it identifies misconfigurations, overly permissive rules, and differences across your services.

example

bash
curl -s https://cross-origin-resource-policymapper.apimesh.xyz/check?urls=https://api1.example.com,https://api2.example.com

sample output:
{
"results": {
"https://api1.example.com": { "cors": "allow all", "issues": ["overly permissive"] },
"https://api2.example.com": { "cors": "restricted", "issues": [] }
}
}

how it works

it fetches responses from configured endpoints, inspects the CORS headers and policies, then compares them against best practices. it automates what you'd otherwise do manually — making sure your configs stay tight.
