Tempest AI Content Engine — Text Expand

Choose this endpoint when you need to systematically lengthen existing text content — such as product descriptions, blog drafts, or email copy — with control over writing style and expansion factor. It is distinct from a general rewrite or summarization endpoint because the explicit goal is increasing length and depth. Prefer it over generic LLM prompting when you want a pay-per-call, production-grade, deterministic API integration rather than managing your own model context.

• Missing required 'text' field returns a validation error
• Invalid or unsupported 'target_length' value may cause unexpected output length
• Very long input texts may hit token or size limits
• Payment failure (insufficient USDC) blocks the call before processing
• Ambiguous style instructions may produce inconsistently styled output
