how to identify risky subdomains without manual enumeration or heavy auditing

the problem

manually auditing subdomains for exposure or security risks is tedious and error-prone. it’s easy to overlook unused or sensitive subdomains that could be exploited. this process often involves juggling multiple tools and logs, which eats up time and resources.

the solution

subdomain-exposure-score is an api that aggregates subdomain data from dns, certificate transparency logs, and public APIs to give you a clear score of how exposed each subdomain is. this helps you prioritize security checks.

sample request:

bash
curl 'https://subdomain-exposure-score.apimesh.xyz/check?domain=yourdomain.com'

response shape:

{
"domain": "yourdomain.com",
"subdomains": [
{"name": "api.yourdomain.com", "exposure_score": 85},
{"name": "old.yourdomain.com", "exposure_score": 40}
]
}

how it works

it combines data from free dns records, certificate transparency logs, and public APIs. the api analyzes these inputs to score each subdomain for exposure, indicating the risk level and whether it’s active or unused. the calculation considers presence, security certificates, and Internet exposure.
