How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object with a 'text' field containing the HTML-escaped version of the input string, where characters like <, >, &, ", and ' are replaced with their corresponding HTML entities (e.g. <, >, &).
Example use cases
Sanitize user-generated content
“I need to make this user-submitted comment safe to render in HTML — can you escape all the special characters in: '<script>alert("XSS")</script> Hello & welcome!'”
Encode product descriptions for HTML templates
“Take this product description and escape it so I can safely inject it into an HTML template: 'Sizes: S, M & L — price <$50 for most items'”
Prepare API response text for web display
“This API returned some text with angle brackets and ampersands in it — can you HTML-encode it so it displays correctly in the browser without breaking the markup: 'Result: a < b && c > d'”
