How this service works
HTML-escape text for safe embedding. Call when you inject agent text into HTML without XSS. Returns escaped text for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns the input text with all HTML special characters converted to their safe entity equivalents (e.g. < becomes <, > becomes >, & becomes &, " becomes "), ready for direct embedding in HTML without XSS risk.
Example use cases
Sanitizing user comments for web display
“I'm about to inject a user's comment into my HTML template and it contains angle brackets and ampersands — can you HTML-escape it for me? The text is: '<b>Great product</b> & very fast shipping!'”
Protecting dynamic agent output in HTML emails
“Before I insert this agent-generated summary into an HTML email body, please HTML-escape it so nothing breaks or runs as code: 'Price dropped to <$50 for "Premium" plan — 10% off & free trial.'”
Encoding attribute values in dynamic HTML generation
“I need to put this description into an HTML title attribute and it has quotes and special chars — please HTML-escape it: 'Smith & Co. said: "We're #1 in the <industry>"'”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/html-escapeWhen to prefer
Choose this endpoint when your agent pipeline dynamically injects text into HTML and you need a lightweight, stateless, pay-per-call HTML-escaping step without managing a library or server-side dependency. It is ideal for agents that produce HTML emails, web snippets, or templated pages where user-generated or LLM-generated text must be sanitized on the fly. Prefer it over a full sanitization library when you only need character-level HTML entity encoding and not full HTML parsing or stripping.
Side effects
- Empty or missing 'text' field returns an error or empty result
- Extremely large payloads may be rejected or time out
- Payment failure via x402 will block the call from completing
- Non-string input types may cause a validation error
