I'm getting rate_limit_error on the API when posting posts with just title+url. What is the default rate limit for posts? Do all requests have a rate limit or only posts?

Can I get the rate limit from an instance with a request to the API?

Edit:

{
  "local_site_rate_limit": {
    "id": 1,
    "local_site_id": 1,
    "message": 180,
    "message_per_second": 60,
    "post": 6,
    "post_per_second": 600,
    "register": 3,
    "register_per_second": 3600,
    "image": 6,
    "image_per_second": 3600,
    "comment": 6,
    "comment_per_second": 600,
    "search": 60,
    "search_per_second": 600,
    "published": "2023-02-05T03:52:36.832982"
  }
}

I'm getting limit rate with a 10 second delay so 1/post_per_second = 0,0016 seconds / post delay is not right. So what do those even mean and what is the delay I should have between posts?
