Basic scrape feature:

params = {}
promptapi.scraper('https://pypi.org/classifiers/', params).then(result => {
if(result.error){
console.log(result.error)
} else {
console.log(result.data); // your scraped data...
console.log(result.headers);
console.log(result.url);
promptapi.save('/tmp/data.html', result.data) // save result
}
})
```
Output:
// result.data
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="defaultLanguage" content="en">
<meta name="availableLanguages" content="en, es, fr, ja, pt_BR, uk, el, de, zh_Hans, ru, he">
:
:
:
// result.headers
{ 'Content-Length': '322126', ...
// result.url
https://pypi.org/classifiers/
/tmp/data.html saved successfully, written 322126 bytes
You can add url parameters for extra operations. Valid parameters are:
- `auth_password`: for HTTP Realm auth password
- `auth_username`: for HTTP Realm auth username
- `cookie`: URL Encoded cookie header.
- `country`: 2 character country code. If you wish to scrape from an IP address of a specific country.
- `referer`: HTTP referer header
- `selector`: CSS style selector path such as `a.btn div li`. If `selector` is
enabled, returning result will be collection of data and saved file will be
in `.json` format.
```javascript
const promptapi = require('@promptapi/scraper-pkg')
params = {country: 'EE', selector: 'ul li button[data-clipboard-text]'}
promptapi.scraper('https://pypi.org/classifiers/', params).then(result => {
if(result.error){
console.log(result.error)
} else {
console.log(result.data); // your scraped data...
console.log(result.headers);
console.log(result.url);
promptapi.save('/tmp/data.json', result.data)
}
})
```
Output :
// result.data
[ '<button class="button button--small margin-top margin-bottom copy-tooltip copy-tooltip-w" data-clipboard-text="Development Status :: 1 - Planning" data-tooltip-label="Copy to clipboard" type="button">\n Copy\n</button>\n',
'<button class="button button--small margin-top margin-bottom copy-tooltip copy-tooltip-w" data-clipboard-text="Development Status :: 2 - Pre-Alpha" data-tooltip-label="Copy to clipboard" type="button">\n Copy\n</button>\n',
'<button class="button button--small margin-top margin-bottom copy-tooltip copy-tooltip-w" data-clipboard-text="Development Status :: 3 - Alpha" data-tooltip-label="Copy to clipboard" type="button">\n Copy\n</button>\n',

You can also add extra `X-` headers to your request. Read more about http
headers at [Mozilla](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers)’s website.
```javascript
const promptapi = require('@promptapi/scraper-pkg')
params = {}
headers = {'X-Referer': 'https://www.google.com'}
promptapi.scraper('https://pypi.org/classifiers/', params, headers=headers).then(result => {
if(result.error){
console.log(result.error)
} else {
console.log(result.data); // your scraped data...
console.log(result.headers);
console.log(result.url);
promptapi.save('/tmp/data.html', result.data) // save result
}
})
