# AgentTools URL Encoder/Decoder

> AgentTools URL Encoder/Decoder is a paid API for AI agents from agenttools-hub.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Percent-encodes text for safe inclusion in URLs and query strings, or decodes percent-encoded text back, using 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-adf0bc7e
```

Example prompt: Can you percent-encode this text so I can safely use it in a URL query string: 'hello world & more=yes'?

## When to prefer this

Use this endpoint when an agent needs to safely prepare text for inclusion in URLs or query strings, or when it needs to interpret percent-encoded data received from web sources. Prefer this over custom logic when the agent must handle special characters, spaces, Unicode, or emoji in URL contexts reliably.

## Known failure modes

- Missing required 'text' query parameter returns an error
- Invalid 'op' value other than 'encode' or 'decode' may cause unexpected behavior
- Malformed percent-encoded input when decoding (e.g. a lone % sign) may return an error or partial result
- Network timeout on the Vercel serverless host under cold-start conditions

## 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 (with spaces as %20, special characters escaped per encodeURIComponent rules) when encoding, or the decoded plain-text string when decoding.
