## `POST /v1/barcode/read/from/url`

## Attributes

<Note>Attributes are case-sensitive and should be inside JSON for POST request. for example: `{ "url": "https://example.com/file1.pdf" }`</Note>

### types

Detects checkboxes, radiobuttons, vertical and horizontal lines, and general segments (all content types) on scanned documents using the barcode reader engine.

Comma-separated list of object types to decode, must be in a string format.

## Visual Element Detection Modes

* Checkbox: Locates check boxes.
* Segment: Locates and selects objects on a page (general selection).
* UnderlinedField: Detects fillable fields (typically, underlined spaces, i.e. fields to fill in a form).
* Rectangle: Detects rectangles, including checkboxes. Also returns the value as 1 if a checkmark or a filled rectangle was detected.
* Oval: Detects rounded or oval marks (typically, a radiobutton). Returns value of 1 if filled out radiobutton was detected.
* HorizontalLine: Detects horizontal lines.
* VerticalLine: Detects vertical lines.

<Note>
  **Inconsistent URL Encoding in cURL Output:** When using cURL to make API requests, the output JSON may show URL characters encoded as Unicode escape sequences. For example, the ampersand character (`&`) may appear as `\u0026` in the cURL output. This is normal JSON encoding behavior and does not affect the validity of the URL. The URL will function correctly when used, as JSON parsers automatically decode these escape sequences. If you're parsing the response programmatically, your JSON parser will handle this conversion automatically.
