Our API is free to use for most sites. It's so simple to integrate - just four, brief, beautiful lines of code - that even I can do it solo. You post a URL, and we return the hosting company via XML.
So that we may continue to provide free API access, we respectfully request that:
1) Your site links the hosting company displayed back to WhoIsHostingThis.com.
2) The results are clearly visible on the page.
Interested in learning more? We've love to hear how you plan to use our API. Give us a brief outline, and we'll get back to you ASAP.
