InsightVM Cloud Integrations API - search by asset tag?

How can I search by asset tag in the v4 asset search API? As a reference, this is part of my list of assets (with lots of field removed for brevity):

$ curl -X POST -H "X-Api-Key: XXX" -H "Content-Type: application/json" https://us2.api.insight.rapid7.com/vm/v4/integration/assets

{
  "data" : [ {
    "assessed_for_policies" : false,
    "tags" : [ {
      "name" : "other vms",
      "type" : "SITE"
    } ],
    "total_vulnerabilities" : 230,
    "new" : [ ],
    "remediated" : [ ]
  } ]
}

I’ve confirmed that searching based on various fields (e.g., ip, os_family, etc.) works, but I can’t search on tags:

$ curl -X POST -H "X-Api-Key: XXX" -H "Content-Type: application/json" -d "{\"asset\": \"tags IN ['other vms']\"}" https://us2.api.insight.rapid7.com/vm/v4/integration/assets
{
  "data" : [ ],
  "metadata" : {
    "number" : 0,
    "size" : 10,
    "totalResources" : 0,
    "totalPages" : 0,
    "cursor" : null
  },
  "links" : [ {
    "href" : "https://us2.api.insight.rapid7.com:443/vm/v4/integration/assets?page=0&size=10&sort=id,asc",
    "rel" : "self"
  } ]
}

OK, this doesn’t work, but surely the inverse will, right?

$ curl -X POST -H "X-Api-Key: XXX" -H "Content-Type: application/json" -d "{\"asset\": \"tags NOT IN ['other vms']\"}" https://us2.api.insight.rapid7.com/vm/v4/integration/assets
{
  "data" : [ ],
  "metadata" : {
    "number" : 0,
    "size" : 10,
    "totalResources" : 0,
    "totalPages" : 0,
    "cursor" : null
  },
  "links" : [ {
    "href" : "https://us2.api.insight.rapid7.com:443/vm/v4/integration/assets?page=0&size=10&sort=id,asc",
    "rel" : "self"
  } ]
}

What about CONTAINS?

$ curl -X POST -H "X-Api-Key: XXX" -H "Content-Type: application/json" -d "{\"asset\": \"tags CONTAINS 'other vms'\"}" https://us2.api.insight.rapid7.com/vm/v4/integration/assets
{
  "data" : [ ],
  "metadata" : {
    "number" : 0,
    "size" : 10,
    "totalResources" : 0,
    "totalPages" : 0,
    "cursor" : null
  },
  "links" : [ {
    "href" : "https://us2.api.insight.rapid7.com:443/vm/v4/integration/assets?page=0&size=10&sort=id,asc",
    "rel" : "self"
  } ]
}

Maybe =?

$ curl -X POST -H "X-Api-Key: XXX" -H "Content-Type: application/json" -d "{\"asset\": \"tags = 'other vms'\"}" https://us2.api.insight.rapid7.com/vm/v4/integration/assets
{
  "_type" : "com.rapid7.spring.rest.error.resource.ErrorResource",
  "status" : 400,
  "localized_message" : null,
  "message" : "Your query string format is not valid. It has 1 error: The operator '=' cannot be used with the data type 'STRINGS'",
  "throwable" : null
}

So I know for sure that tags is a) indexed and b) is string array, which is interesting since it’s an object to begin with. Is there a special syntax for the string value that I’m not aware of or some other insight someone can give me on how to search against this field? Thanks.

what about getting all the assets of a tag, them looping through those calling the assets?

/api/3/tags/{id}/assets

That’s the on-prem InsightVM API, isn’t it? We can only use the cloud-based one.
