Percolate APIs support a batch GET of objects through an ids parameter.
As an example, a single GET operation can be issued to retrieve the three separate post objects as follows.
curl "https://percolate.com/api/v5/post/?ids=post:1,post:2,post:3" \
-X "GET" \
-H "Authorization: Bearer {your_access_token}" \
-H "Content-type: application/json; charset=utf-8"
