Creator Desk Prefix Lines Utility

Choose this endpoint when you need a simple, reliable, pay-per-use utility to prepend a fixed prefix string to every line of a text block — especially in an autonomous agent pipeline where you want a deterministic, stateless text transformation without setting up your own string-processing logic. It is well-suited for formatting tasks like quoting, commenting, tagging, or annotating multiline text.
