# AgentTools URL Encoder / Decoder

> AgentTools URL Encoder / Decoder is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-12).

Percent-encodes plain text for safe use in URLs and query strings, or decodes percent-encoded text back to plain text, using standard encodeURIComponent rules.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agenttools-url-encoder-decoder-ddaedb38
```

Example prompt: Can you percent-encode the string 'hello world & welcome!' so I can safely use it in a URL query parameter?

## When to prefer this

Use this endpoint when an agent needs to programmatically encode or decode URL components without running code locally — especially in no-code or low-code agent workflows where JavaScript's encodeURIComponent is unavailable. Prefer it over custom logic when strict RFC-compliant percent-encoding is needed for query strings.

## Known failure modes

- Missing required 'text' query parameter returns an error
- Invalid 'op' value (not 'encode' or 'decode') returns a validation error
- Passing already-encoded text to encode may double-encode it
- Passing malformed percent sequences to decode may return an error or partial result

## How this service works

Percent-encode text for safe inclusion in URLs and query strings, or decode percent-encoded text back. Uses the standard encodeURIComponent rules. Use this when an agent needs to percent-encoding for query strings and URLs.

## Output

Returns the transformed string — either the percent-encoded version of the input text (with spaces as %20, special characters as their hex equivalents, etc.) or the decoded plain-text version of a percent-encoded input, following standard encodeURIComponent rules.
