How this service works
Fetch a URL and analyse its Content-Security-Policy header: presence, unsafe-inline, unsafe-eval, wildcard sources and parsed directives.
Output
Returns whether a CSP header is present on the target URL, whether it contains unsafe-inline or unsafe-eval directives, any wildcard sources found, and the full parsed list of CSP directives and their values.
Example use cases
Pre-launch security header check
“Before we ship our new site at https://myapp.io, can you audit its Content-Security-Policy header and tell me if there are any dangerous settings like unsafe-inline or unsafe-eval?”
Third-party vendor CSP audit
“I need to vet a vendor's security practices — can you fetch https://vendorportal.com and analyze its CSP header to see if it's properly configured or has wildcard sources?”
Ongoing security compliance review
“As part of our quarterly security review, check https://dashboard.ourcompany.com for its Content-Security-Policy and list all the parsed directives along with any unsafe flags detected.”
Technical details
Endpoint
GEThttps://164.160.90.241.sslip.io/api/sec-header-csp-analyzer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, automated audit of a specific URL's Content-Security-Policy header without running a full security scanner. Ideal for pre-launch checks, vendor due diligence, or compliance reviews where CSP posture is the primary concern. It is more focused than a general security header scanner and provides parsed directive-level detail rather than just a pass/fail.
Side effects
- URL is unreachable or times out — endpoint may return an error or empty result
- Target site does not set a CSP header — result will indicate absence
- Malformed URL input — may return a validation error
- Target site blocks automated HTTP clients — fetch may fail
- CSP header is present but malformed — parsing may produce incomplete directives
