I'm trying to check by a post title if post exist or not. For some reason when i try something like:
http://domain.com/wp-json/wp/v2/posts?filter[post-title]=table
I want if post with the name table exist, to get the post, if not, get an empty response. But for some reason when post with title not exist i get all posts back. How could get empty when no post exist and the post when it exist.

It's not well documented in the official Wordpress docs yet (https://developer.wordpress.org/rest-api/reference/posts/#arguments), but you can achieve a rest api search by post title with the combination of search
and search_columns
. search_columns
is an enum, though, which I've noticed after trial & error, resulting in this error message:
search_columns[0] is not one of post_title, post_content and post_excerpt
Example, list all posts that contain "table" in their titles, and only in their titles:
http://example.com/wp-json/wp/v2/posts?search=table&search_columns=post_title

You cannot do this through wp json, please copy the following code in the functions.php:
function __search_by_title_only( $search, &$wp_query ) {
global $wpdb;
if ( empty( $search ) )
return $search; // skip processing - no search term in query
$q = $wp_query->query_vars;
$n = ! empty( $q['exact'] ) ? '' : '%';
$search =
$searchand = '';
foreach ( (array) $q['search_terms'] as $term ) {
$term = esc_sql( like_escape( $term ) );
$search .= "{$searchand}($wpdb->posts.post_title LIKE '{$n}{$term}{$n}')";
$searchand = ' AND ';
}
if ( ! empty( $search ) ) {
$search = " AND ({$search}) ";
if ( ! is_user_logged_in() )
$search .= " AND ($wpdb->posts.post_password = '') ";
}
return $search;
}
add_filter( 'posts_search', '__search_by_title_only', 500, 2 );

Unfortunately it is not possible, but you can use slug instead. Slug is editable part of the URL when writing a post and they can represent title of the page (or it can be changed into this).
http://example.com/wp-json/wp/v2/posts?slug=table

According to http://v2.wp-api.org/, some have to use search
keyword :
http://domain.com/wp-json/wp/v2/posts?search=table
.
