Total Artist Release

How can i get all the releases of an artist by api as for now when i call api for artist lookup i am getting only max 25 releases?

You can receive up to 100 entries at a time by setting the limit=100 argument. You can page through the results with the offset=n parameter. So e.g. limit=100&offset=0 will give you the first 100 results, limit=100&offset=1 the next 100 and so on.
