If you'd prefer to host the data locally, you can purchase the Words API data set. Purchase of the Words API data set entitles you to use the data as much as you want, for as long as you want. Load the data directly into your app, make games with it, train an AI to take over the world with it.
The only things you cannot do with the data are resell it, or use it in a service that competes directly with WordsAPI. And we'd really prefer you didn't use it to train an AI to take over the world.
The sample file contains a random selection of 10% of the full Words API data set.
