I'm also looking for this and it's related to #160

We have some content on our site which comes from an API. There is a registered post type, but it's empty and any requests for posts of that type go through the API for the content. I was looking through the Hooks class hoping it was possible to pass a URL to some method to clear a page by URL instead of the ID but nothing currently exists.

Possible new method for Hooks:

public function purgeCacheByUrl($url)
{
    $wpDomainList = $this->integrationAPI->getDomainList();
    if (!count($wpDomainList)) {
        return;
    }
    $wpDomain = $wpDomainList[0];
    $zoneTag = $this->api->getZoneTag($wpDomain);
    if (!isset($zoneTag)) {
        return;
    }

    // Don't attempt to purge anything outside of the provided zone.
    if (!Utils::strEndsWith(parse_url($url, PHP_URL_HOST), $wpDomain)) {
        return;
    }

    $isOK = $this->api->zonePurgeFiles($zoneTag, array($url));

    $isOK = ($isOK) ? 'succeeded' : 'failed';
    $this->logger->debug("purgeCacheByUrl " . $isOK);
}

Would this be accepted as a pull request?

Addition to you code we should add this filter also in cloudflare.loader.php after line number 104

$cloudflarePurgeIndividualURLActions = apply_filters('cloudflare_purge_individual_url_actions', $cloudflarePurgeIndividualURLActions);

foreach ($cloudflarePurgeIndividualURLActions as $action) {
    add_action($action, array($cloudflareHooks, 'purgeCacheByUrl'), PHP_INT_MAX);
}

If anyone is looking for a quick fix, I ended up adding the creds as constants in the wp-config.php file. This is the relevant part of the function that clears various caches when passed a URL:

	// Check if the cloudflare constants are defined.
	if ( defined( 'CLOUDFLARE_ZONE_ID' ) && defined( 'CLOUDFLARE_API_KEY' ) && defined( 'CLOUDFLARE_EMAIL' ) ) {
		$ch = curl_init();
		curl_setopt( $ch, CURLOPT_URL, 'https://api.cloudflare.com/client/v4/zones/' . CLOUDFLARE_ZONE_ID . '/purge_cache' );
		curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
		curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, 'DELETE' );
		$headers   = array();
		$headers[] = 'X-Auth-Email: ' . CLOUDFLARE_EMAIL;
		$headers[] = 'X-Auth-Key: ' . CLOUDFLARE_API_KEY;
		$headers[] = 'Content-Type: application/json';
		curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers );
		$data = '{"files":["' . $url_to_flush . '"]}';
		curl_setopt( $ch, CURLOPT_POSTFIELDS, $data );

		$result = curl_exec( $ch );
		if ( curl_errno( $ch ) ) {
			$response .= 'Error clearing Cloudflare. ';
		}
		$responseObj = json_decode( $result );
		if ( isset( $responseObj->success ) && $responseObj->success ) {
			$response .= 'Cloudflare cleared. ';
		}
		curl_close( $ch );
	}
