What is an end point?
An end point is a URL that you can call which will return a response.
In the header bidding world, an end point is usually called from the browser with parameters (size of placement, auction id, callback function, etc) and returns a response containing an ad information (ad url, price, etc).
Some exchanges offer the possibility to call an end point and request multiple placements into one single call. This reduces the number of calls in a page.
What is a wrapper?
A wrapper is a container that let publishers put ad impressions up for simultaneous bids by multiple groups of buyers.
A client-side wrapper will call one or many exchanges (SSPs and/or DSPs) via end points from the browser of the user. Each exchange will perform a second-price auction. The wrapper will compare the final result of each exchange second-price auction and select the highest value.
A server-side solution will call one or many exchanges (SSPs and/or DSPs) from a server. They will each compete from a single second-price auction.
In the ecosystem of internet ads, there will always be differences between the primary and the third party ad server. When the publisher's ad server returns the third party ad, it is considered rendered, thus, an impression is counted. The third party creative then begins to render and is then impacted by variables such as user match times, user bid times, connectivity, or simply the user leaves the page before the actual ad has time to display and get counted as an impression.
Transparency mostly depends on the source of inventory and the system(s) used to buy that inventory. The industry is moving towards full URL transparency, but some publishers may choose to make their inventory semi-transparent (domain only) or fully blind (usually user matching only). Some systems will allow full reporting after the campaign is complete, and some systems restrict this data per agreements made with their exchanges and publishers.
