As it turns out the current version / api endpoint we use does not have historical transaction price in its response: we only have time, size and buyer.
We played around with version string in request header and get params, but didn't get a different response.
Presumably it's the API endpoint that matters.

Our current sign value does not with the second api endpoint: 500 or 403 are both triggered.
