Wordpress API send message

I am an experienced PHP programmer, familiar with CURL and using it with a cookie, and also comfortable with JSON.

That I am not familiar with WordPress 4.1.1, and my goal is simple: remotely invoke a WordPress site both natively and with a plugin (hopefully from the beginning) and:

a) send an article / message and hopefully

b) get a list of user messages sorted by date, as well (for comparison).

From the research so far, I see that you need to log in, and maybe this is a two-step process, including receiving nonce and then sending the message using nonce. Can someone tell me where to look for API documentation or where to start?

// initialize curl
$ch = curl_init();
// set url ie path to xmlrpc.php

// xmlrpc only supports post requests
curl_setopt($ch, CURLOPT_POST, true);
// return transfear
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// setup post data
$content = array(
  'post_type' => 'post',
  'post_content' => 'This is the post content',
  'post_title' => 'This is the post title',
  'post_status' => 'publish',
);
// parameters are blog_id, username, password and content
$params = array(1, '<user>', '<password>', $content);
$params = xmlrpc_encode_request('wp.newPost', $params);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
// execute the request
curl_exec($ch);
// shutdown curl
curl_close($ch);

, wp.getPosts, , , :

// filter used when retrieving posts
$filter = array(
  'post_type' => 'post',
  'post_status' => 'publish',
  'number' => 50,
  'offset' => 0,
  'orderby' => 'post_title',
);
// fields to include in response
$fields = array(
  'post_title',
  'post_author',
  'post_id',
  'post_content',
);
$params = array(1, '<username>', '<password>', $filter, $fields);
$params = xmlrpc_encode_request('wp.getPosts', $params);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
// execute query
$response = curl_exec($ch);
// response is xml
$response = simplexml_load_string($response);
// walk over response and figure out if post should be displayed or not
