Recommendations By POAPs

Learn how to construct queries to build a recommendation engine based on POAPs collected by the user(s).

You can use POAP for building a contact recommendation feature for your user to help them connect with users that attend relevant events in the past. To build such a contact recommendation feature, you will need to take two steps:

1. Query Get POAPs from a given user(s)

2. Use the list of POAPs held from Query #1 as an input to query Get all addresses and ENS of the attendees of a given POAP event(s)

In the future, Airstack will provide a dedicated recommendation API that will combine the two steps into one.

Get POAPs from a given user(s)

Query

query GetAllPOAPs($address: [Identity!]) {
  Poaps(input: {filter: {owner: {_in: $address}}, blockchain: ALL, limit: 10}) {
    Poap {
      id
      eventId
      poapEvent {
        eventName
        eventURL
        startDate
        endDate
        country
        city
        contentValue {
          image {
            extraSmall
            large
            medium
            original
            small
          }
        }
      }
      owner {
        identity
        primaryDomain {
          name
        }
        addresses
      }
    }
  }
}

  "address": ["dwr.eth", "fc_fname:vbuterin"]
}

Get all addresses, web3 socials and ENS of the attendees of a given POAP event(s)

Query

query GetAllAddressesSocialsAndENSOfPOAP($eventId: [String!]) {
  Poaps(input: {filter: {eventId: {_in: $eventId}}, blockchain: ALL, limit: 10}) {
    Poap {
      owner {
        identity
        primaryDomain {
          name
        }

        }
      }
      poapEvent {
        eventId
      }
      tokenId
    }
  }
}
