Paging Through a Large Document

Use offset-based paging to read through a document that exceeds the 40,000 character limit:

curl "https://api.midlyr.com/api/v1/regulations/01HXZ3K.../content?offset=0&limit=40000"
curl "https://api.midlyr.com/api/v1/regulations/01HXZ3K.../content?offset=40000&limit=40000"

Continue incrementing offset until hasMore is false.
