How this service works
Call when an agent needs the color-scheme meta value extracted from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/profile-color-scheme first.
Output
Returns the extracted value of the color-scheme meta tag (e.g. 'light', 'dark', 'light dark', or null if not present) from the target page or HTML input.
Example use cases
Dark mode compatibility check
“Check whether https://stripe.com declares a color-scheme preference in its meta tags — I want to know if it officially supports dark mode.”
Brand theming audit from HTML
“Here's the raw HTML of our competitor's landing page — can you pull out the color-scheme meta value so I know what theme they're targeting?”
Batch site metadata research
“I'm auditing design metadata for a list of SaaS homepages — start with https://linear.app and tell me what color-scheme meta value they've declared.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-color-scheme?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the color-scheme meta tag value from a webpage or raw HTML and want SSRF-safe remote fetching without spinning up a full browser. Prefer the free sandbox endpoint (/v1/sandbox/profile-color-scheme) for testing. Choose this over general-purpose scrapers when you only need this single meta value and want a low-cost, targeted extraction.
Side effects
- URL points to a private/internal IP address (SSRF blocked, rejected)
- URL is unreachable or returns a non-200 status
- HTML input exceeds 200,000 character limit
- No color-scheme meta tag found in the document (returns null or empty)
- Malformed URL rejected by input validation
- Page requires JavaScript rendering to expose meta tags (static fetch may miss dynamically injected tags)
