how to automate your csp generation based on real-world site data without guesswork

the problem

creating effective content security policies (csp) is hard. manually analyzing resource loads and responses is time-consuming and error-prone, especially for complex sites with multiple third-party resources.

the solution

the csp-policy-heuristics api automates this process. it analyzes your website's responses and resource loads, then suggests a tailored csp that blocks insecure or unnecessary sources. for example:

curl -X GET https://csp-policy-heuristics.apimesh.xyz/check?url=https://example.com

// sample output
{
  "policy": "default-src 'self'; img-src 'self' data:; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'",
  "issues": ["blocked insecure image resource from http://badsource.com"]
}

how it works

it scrapes your website's responses and resource loads, combining multi-source data to identify insecure or unnecessary resource usage. it then recommends a strong, context-aware csp based on this data to help you improve your security posture.
