Manage to resolve it, was making very stupid mistake.

here is how document will look like in cloudant

 {
  "_id": "_design/agentapp",
  "_rev": "2-ede711dde1923`enter code here`1092dd7bebc4c22811d",
  "filters": {
    "by_agent": "function(doc, req) { return doc.agent ===   req.query.agent;}"
  }
}

working curl request https://host/database/_changes?filter=agentapp/by_agent&agent=1
