apcPaid property
Information about the paid APC (article processing charge) for this work. The object contains: value: Integer currency: String provenance: String — currently either openapc or doaj, but more will be added; see below for details. value_usd: Integer — the APC converted into USD You can find the listed APC price (when we know it) for a given work using apc_list. However, authors don’t always pay the listed price; often they get a discounted price from publishers. So it’s useful to know the APC actually paid by authors, as distinct from the list price. This is our effort to provide this. Our best source for the actually paid price is the OpenAPC project. Where available, we use that data, and so apc_paid.provenance is openapc. Where OpenAPC data is unavailable (and unfortunately this is common) we make our best guess by assuming the author paid the APC list price, and apc_paid.provenance will be set to wherever we got the list price from.
