## Endpoint reference

### URL Encode / Decode

`POST https://api.eu.apyhub.com/freedailypro/text-encoding-decoding-api/security/url` · 10 atoms · accepts `application/json` · returns `application/json`

| Parameter | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `text` | body | string | yes |  |
| `action` | body | string | yes | One of: encode, decode. |
| `component` | body | boolean | no |  |

#### Quickstart

Encode or decode a piece of text for security URL handling with the required action and text fields.

```bash
curl -X POST "https://api.eu.apyhub.com/freedailypro/text-encoding-decoding-api/security/url" \
  -H "apy-token: $APY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "https://example.com/login?token=abc123",
    "action": "encode"
  }'
```

#### What you'll get back

The live response to the request above:

```json
{
  "tool": "Url encoder client and server side from freedailypro",

## About

## What it does
Text Encoding Tools converts text between common web-safe formats. Send plain text and choose an action, and you get the transformed string back in a structured response.

Use the URL encoder to encode or decode text, with an optional `component` flag for URL component handling. Use the HTML entity converter to encode or decode HTML entities. Use the binary and ASCII converter to transform text to and from binary or hex, with optional `separator` support when encoding or decoding binary and hex strings.

Each endpoint returns the performed `action` and the converted `result`, along with the `tool` name that produced it. That makes it straightforward to plug into validation flows, content pipelines, or internal utilities that need deterministic text transformations.

Text Encoding Tools fits frontend sanitisation, query-string building, template rendering, and low-level debugging where you need to inspect or normalize encoded data without guessing how it was transformed.
