query Contract_token_metadata {

        limit: 100
        where: {
            contract: {
                hash: {
                    _eq: "\\x01b10f6d79aa4b556a6c5a067596ca02d8dbf6566f1fbceee136bdaadd9fedc8"

            }
        }
    ) {
        metadata
        contract {
            hash
        }
        uri
        created_at
        token_id
        type
        updated_at
    }
}

query State {
    state {
        last_time
        last_height
        name
    }
}

Self hosted mode

  • Create .env file relying on .env.example
  • Get Starknet node url endpoint for example on Blast API and fill up NODE_URL variable
  • Run docker compose up --build
