WordPress Rest API get total post count

Question

I am using the following to get posts

http://demo.wp-api.org/wp-json/wp/v2/posts

I the max limit on posts is 100 per request.

So I would have to make multiple requests to get all posts.

How can I get the total post count so I know how many requests I have to make?

Thanks.

The response headers include this data:

To determine how many pages of data are available, the API returns two header fields with every paginated response:

• X-WP-Total: the total number of records in the collection
• X-WP-TotalPages: the total number of pages encompassing all available records

By inspecting these header fields you can determine how much more data is available within the API.
