how to identify obsolete subdomains before they become security liabilities

the problem

keeping track of all your subdomains and their security status can be a nightmare. outdated or exposed subdomains can be an easy entry point for attackers, but enumerating and analyzing them manually is slow and incomplete.

the solution

with the subdomain-exposure-heatmap api, you can automate subdomain enumeration and get a clear visualization of their exposure risks. simply make a request like:

curl -X GET "https://subdomain-exposure-heatmap.apimesh.xyz/check?domain=example.com"


heres what the output might look like:


{
  "subdomains": [
    {"name": "api.example.com", "exposure_level": "high"},
    {"name": "old.example.com", "exposure_level": "medium"}
  ]
}


### how it works
this api searches through free dns records and certificate transparency logs to find all subdomains. it then assesses exposure risk levels based on recent certificate data, DNS configurations, and known vulnerabilities. the result is a heatmap that highlights insecure or obsolete endpoints.
