How this service works
URL-encode a component. Use before building query strings or safe path segments. Returns encodeURIComponent-style output for the input text. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
Output
Returns a JSON object containing the percent-encoded version of the input text, applying encodeURIComponent-style encoding where characters like spaces, ampersands, slashes, question marks, and other special characters are replaced with their %XX hex equivalents, making the string safe for use as a URL query parameter or path segment.
Example use cases
Encoding search query for API call
“I need to embed the search term 'coffee & tea (hot)' into a URL query string — can you URL-encode it so it's safe to append after ?q=?”
Safe path segment for dynamic URL
“I'm building a URL that includes a user-supplied filename like 'my report 2024/final.pdf' — please percent-encode it so it works as a URL path segment without breaking the URL structure.”
Encoding OAuth redirect URI
“I need to URL-encode my redirect URI 'https://myapp.com/callback?source=oauth' so I can pass it as a parameter in an authorization URL — can you encode it using encodeURIComponent-style encoding?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/url-encode-componentWhen to prefer
Prefer this endpoint when you need encodeURIComponent-style encoding (i.e., encoding suitable for query parameter values and path segments, encoding characters like '/', '?', '&', '=', '#') rather than full URL encoding. Choose this over the sibling 'Delx URL Encode' endpoint when you specifically want component-level encoding rather than general URL encoding or decoding. Ideal for agents building dynamic URLs from user-supplied text without needing an API key or subscription.
Side effects
- Input text exceeds 100,000 character limit — request rejected with a validation error
- Empty or missing 'text' field — returns a structured validation error without billing
- Malformed JSON request body — returns a parsing error
- Network or payment (x402) authentication failure — call not processed
