      The number of recursive upstream AS-SETs

    - `asn_cone_size: number`

      The number of unique ASNs in the AS-SETs recursive downstream

    - `irr_sources: array of string`

      The IRR sources of the AS-SET

    - `name: string`

    - `inferred_asn: optional number`

      The inferred AS number of the AS-SET

    - `peeringdb_asn: optional number`

      The AS number matching PeeringDB record

  - `paths: array of array of string`

    Paths from the AS-SET that include the given AS to its upstreams recursively

- `success: boolean`
