How this service works
Reads the Content-Security-Policy header of a site's home page and lists weak points: 'unsafe-inline' and 'unsafe-eval' in script sources, bare wildcards, data: or http: script sources, a missing default-src or script-src, and a missing policy altogether. Reports directives. Header only; a CSP in a meta tag is not read.
Output
Returns the parsed Content-Security-Policy HTTP header directives for the target domain's home page, along with a list of identified weak points including: presence of 'unsafe-inline' or 'unsafe-eval' in script-src, bare wildcard sources, data: or http: scheme script sources, and whether default-src or script-src directives are missing or the policy is absent altogether. Does not read CSP from HTML meta tags.
Example use cases
Pre-launch security header audit
“Before we go live, can you check the CSP header on staging.mycompany.com and flag any dangerous settings like unsafe-inline, bare wildcards, or missing script-src directives?”
Competitor security posture check
“I want to know how strict stripe.com's Content-Security-Policy is — does it have any weak points like unsafe-eval or data: script sources?”
Compliance review for client site
“Can you pull the CSP header for clientsite.io and give me a report on whether it's missing a default-src, allows unsafe-inline, or has any other policy weaknesses I should flag in my security review?”
Technical details
Endpoint
GEThttps://api.webintel-api.workers.dev/api/security/csp-evaluator-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, automated check of a specific domain's Content-Security-Policy HTTP header without setting up a full browser-based scanner. It is ideal for lightweight security audits, compliance checks, or CI/CD pipeline integrations where you want to flag known CSP weaknesses (unsafe-inline, unsafe-eval, wildcards, data: sources, missing directives) with a single API call. Not suitable when you need to also check meta-tag-based CSP or perform deep DOM-level security analysis.
Side effects
- Domain not found or DNS resolution failure
- Target site does not return a CSP header (reported as missing policy)
- Site returns a malformed or unparseable CSP header
- Request times out if the target domain is slow to respond
- CSP embedded in a meta tag is not detected (HTTP header only)
- Non-existent or invalid domain format returns an error
