## When to prefer this

Choose this endpoint when you need a ready-to-use persuasive debate opening statement for a specific topic and a clearly defined side (for or against). It is ideal for students, educators, trainers, and content creators who need structured argumentation quickly without crafting it from scratch. Prefer this over a general chat endpoint when you specifically need a debate-formatted opening argument rather than a free-form essay or explanation.
