How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

A JSON object with ok:true and paid:true, containing the HTML-entity-encoded version of the input string where special characters like <, >, &, ", and ' are replaced with their corresponding HTML entity representations (e.g. <, >, &, ", ').

Example use cases

Sanitize user input for HTML display

“Take this user-submitted comment and encode all the special characters as HTML entities so it won't break or inject anything when I render it on my page: 'Hello <World> & "everyone"!'”

Escape code snippet for web page

“I need to show a raw code example on my website — can you HTML-encode this snippet so the angle brackets and ampersands display as literal text instead of being interpreted as tags? The snippet is: '<div class="box"> & </div>'”

Prepare email content with safe HTML characters

“Encode this string into HTML entities before I insert it into an HTML email template: 'Special offer: 50% off — use code <SAVE50> & save!'”
