How to call keywordtool.io API from WordPress

1. The Keyword Tool API provides endpoints for different search engines like Google, YouTube, Bing, Amazon, and eBay. To use the API, you'll need to obtain an API key from Keyword Tool. [2]

2. Once you have the API key, you can make HTTP requests to the appropriate endpoint. For example, to get keyword suggestions for Google, you would call the `https://api.keywordtool.io/v1/search/google` endpoint. [2]

3. In WordPress, you can use the built-in `wp_remote_get()` function to make the API call. Here's an example:

php
$api_key = 'your_api_key_here';
$seed_keyword = 'example keyword';
$language = 'en'; // language code

$response = wp_remote_get(
    'https://api.keywordtool.io/v1/search/google?keyword=' . urlencode($seed_keyword) . '&language=' . $language,
    array(
        'headers' => array(
            'Authorization' => 'Bearer ' . $api_key
        )
    )
);

if ( is_wp_error( $response ) ) {
    // Handle error
} else {
    $data = json_decode( wp_remote_retrieve_body( $response ), true );
    // Process the keyword data
    print_r( $data );
}

4. In this example, we're making a GET request to the Google keyword search endpoint, passing the seed keyword and language as parameters. We also include the API key in the request headers.

5. The response from the API is then decoded from JSON and you can process the keyword data as needed, such as displaying it on a WordPress page or using it to optimize content.

6. Keep in mind that the Keyword Tool API has usage limits, so you'll need to manage your API calls accordingly. Refer to the Keyword Tool API documentation for more details on the available endpoints and parameters. [2]
