## Data fields

When you send a [url](https://microlink.io/docs/api/parameters/url) to Microlink API, the following data fields are detected by default:

- `author` (e.g., 'SpaceX')\
  A human-readable representation of the author's name.

- `date` (e.g., 2018-01-24T18:39:47.000Z)\

  representation of the date the article was published.

- `description` (e.g., 'First static fire test of Falcon Heavy…')\
  The publisher's chosen description of the article.

- `image` (e.g., https://cdn.instagram.com/…/171196260320789.jpg)\
  An image URL that best represents the article.

- `video` (e.g., 'https://cdn.instagram.com/…/26867070.mp4')\
  A video URL that best represents the article.

- `lang` (e.g., en)\
  An [](https://en.wikipedia.org/wiki/ISO_639-1)

  ISO 639-1

  representation of the url content language.

- `logo` (e.g., 'https://logo.clearbit.com/instagram.com')\
  An image URL that best represents the publisher brand.

- `publisher` (e.g., 'Instagram')\
  A human-readable representation of the publisher's name.

- `title` (e.g., 'Manufactures Advanced Rockets & Spacecraft')\
  The publisher's chosen title of the article.

- `url` (e.g., 'https://instagram.com/p/BeV6tOhFUor')\
  The URL of the article.

When a data field is media content, the following contextual data will be also returned:

- `width`: file width in pixels.
- `height`: file width in pixels.
- `type`: file type extension.
- `size`: file size in bytes.
- `size_pretty` file size in a human readable format.

Moreover, if the media content is playable (such as [video](https://microlink.io/docs/api/parameters/video) or [audio](https://microlink.io/docs/api/parameters/audio)), the following fields will be added as well:

- `duration`: source duration in seconds.
- `duration_pretty` source duration in a human readable format.

You can customize this behavior via [meta](https://microlink.io/docs/api/parameters/meta) and/or [data](https://microlink.io/docs/api/parameters/data) in order to add specific data rules over the target URL.

Additionally, Microlink gives you some HTTP information over the target URL, such as:

- `statusCode`: The HTTP status code associated with the url response.
- `headers`: The HTTP response headers associated with the url response.
- `redirects`: A collection of HTTP redirects, where each entry contains the status code and URL for redirects followed from the original URL.

The service also returns a `status` field to represent the stage of the current transaction.

You can read [format](https://microlink.io/docs/api/basics/format) section to know more about that.
