How this service works
Call when an agent needs the referrer meta value extracted from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/profile-referrer first.
Output
Returns the extracted value of the referrer meta tag (e.g. 'no-referrer', 'origin', 'strict-origin-when-cross-origin') found in the page's HTML head section. If no referrer meta tag is present, returns null or an empty result.
Example use cases
Audit referrer policy on competitor page
“Pull the referrer meta tag value from https://competitor.com/about so I can see what referrer policy they've set.”
Parse referrer from scraped HTML
“I've got this raw HTML from a page — can you extract the referrer meta value from it? Here it is: <html><head><meta name='referrer' content='no-referrer'></head><body></body></html>”
Check referrer setting before link campaign
“Before I run my affiliate campaign, can you check what the referrer meta tag is set to on https://mysite.com/landing-page?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-referrer?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically extract the referrer meta tag value from a page or HTML blob, with guaranteed SSRF safety (no internal network access). Prefer the free sandbox POST /v1/sandbox/profile-referrer endpoint first to avoid the $0.008 USDC charge during development or testing.
