Split an EPUB. With a chapter range (chapterStart and/or chapterEnd) the result is ONE base64-encoded EPUB of exactly those chapters, in order, with the book's metadata, a table of contents limited to them and the fonts and images they use. Without a range the result is a base64-encoded ZIP archive holding one EPUB per chapter.

Get a checkout link so the user can upgrade THIS account to Epublys Pro.
Call this when another tool is refused with `daily_limited` or a Pro-only error, or when the
user asks to upgrade. Returns a Stripe checkout URL to hand to the user — they complete payment
in their own browser.
Creates no charge by itself, and the link is bound to the account that owns the API key being
used, so it cannot be used to pay for anyone else. If the account is already Pro it says so and
returns no link. Needs an API key: without one it returns the pricing URL instead of a checkout
link. Free: 3 operations/day, 5MB per file. Pro: unlimited
daily operations, 30MB per operation, 60 req/min, no branding on output.
