# Delx URL-Encode Component

> Delx URL-Encode Component is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

URL-encodes a text string using encodeURIComponent-style encoding, suitable for safe query string values and URL path segments

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-url-encode-component-f1c4e780 -d '<json body>'
```

Example prompt: URL-encode this text so I can safely use it as a query parameter: 'hello world & goodbye/world?yes=no'

## When to prefer this

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.

## Known failure modes

- 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

## 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.
