How this service works
Machine-readable settlement service
Output
Returns an absolute URL string computed by resolving the provided relative URL against the given base URL, following standard URL resolution rules (RFC 3986).
Example use cases
Normalize scraped anchor hrefs
“I scraped a page and found a relative href like '/about/team' — can you resolve it against the base URL 'https://mysite.com' to get the full absolute link?”
Resolve relative asset paths
“I have a relative asset path '../../assets/style.css' and the current page is at 'https://app.example.com/v2/docs/intro/'. What's the absolute URL for that stylesheet?”
Build canonical URL for sitemap
“I need to turn the relative URL 'posts/2024/my-article' into an absolute URL using base 'https://blog.example.com/' — can you resolve that for me?”

Use this endpoint when you need a lightweight, pay-per-call URL resolution service without standing up your own URL parsing infrastructure, particularly in agent workflows where relative hrefs need to be absolutized on the fly after scraping or parsing HTML.
Side effects

- Relative URL that cannot be resolved against the base (e.g. protocol-relative conflicts)
- Missing required input fields returns validation error
