Get filings from a specific year

Hi,

I am trying to get a list of filings reported in a specific year. I referred to this: https://extractives.companieshouse.gov.uk/developer/endpoints (using /api/year/{year}/json) but I am getting response 404. Has anyone had success using these?

Thanks in advance.

I have just used https://extractives.companieshouse.gov.uk/api/year/2017/json and that returned data.
