Is there any documentation about how to turn Drupal into an oEmbed provider

I did that and it does not seem to work.
Anyway, I would like to customize the embed code, my nodes contain CCK videos fields and I need the videos to be embeddable.

I can see in the last release there are hooks for theming.

However, when I navigate to /services/oembed I get 404
I saw in the code that the oEmbed Provider module seems to expose its API on /oembed/endpoint but when I navigate to /oembed/endpoint?url=http%3A//localhost/node/2 I get the following response:

{"type":"rich","version":"1.0","provider_name":"blah","width":0,"height":0,"title":"Not found","error":1,"html":"Could not find a provider that supports this url"}

Even if I finally find how /oembed/endpoint is working how's Facebook supposed to embed my posts given the spec says the API endpoint should be /services/oembed?

UPDATE:
I just made a test asking the embed code of a youtube video to my server on /oembed/endpoint and it worked!!!
I think something is upside down, I don't want my site to be an oEmbed provider for YouTube but for my own content.

Hi, I found two things that could help solving my problems with this module :)

1. "Could not find a provider that supports this url" issue

despite what I put in the previous comment my urls are in the form "node/nodeId" I use nice urls and pathauto. However the regex that is used in the oembedprovider hook of oembedprovider module specify node/* (line 80 of oembedprovider.module)

function oembedprovider_oembedprovider() {
  $base_url = url('', array('absolute' => TRUE)) . 'node/*';
  return array(
    $base_url => array(
      'callback' => 'oembedprovider_node_provider',
    ),
  );
}

I replaced it with the following:

function oembedprovider_oembedprovider() {
  $base_url = url('', array('absolute' => TRUE)) . '*';
  return array(
    $base_url => array(
      'callback' => 'oembedprovider_node_provider',
    ),
  );
}

and now the API is returning something (though I will have to theme the output I guess)

2. API endpoint

After some research I was baffled by the fact that no provider is actually using the same API endpoint and realized that it was actually not enforced in the specifications...
There, I thought that oEmbed was useless if I need to ask Facebook (or any oEmbed plugin provider) to register my site in their list of providers. I then found out that some providers are specifying the API endpoint in the headers of the resource. For example, YouTube have this kind of thing in their headers:

<link rel="alternate" type="application/json+oembed" href="http://www.youtube.com/oembed?url=http%3A//www.youtube.com/watch?v%3Dp9b4os8S1U4&format=json" title="Thank You" />
<link rel="alternate" type="text/xml+oembed" href="http://www.youtube.com/oembed?url=http%3A//www.youtube.com/watch?v%3Dp9b4os8S1U4&format=xml" title="Thank You" />

But Flickr doesn't...
I am going to try add that to my site and see what happens.
