POSThttps://omni-api-cyan.vercel.app/api/ai/expandWhen to prefer
Choose this endpoint when you need to quickly expand a short text, query, or idea into a more detailed and comprehensive output using AI. It is particularly useful for content creation workflows, enriching sparse data, or elaborating on brief prompts. Prefer this over generic LLM APIs when you want a pay-per-call USDC-based model without subscription commitments.
Side effects
- Missing required 'query' field returns validation error
- Overly vague or empty query may produce low-quality or generic output
- Rate limits or payment failures via x402 may result in 402 Payment Required responses
- Network timeouts on Vercel serverless infrastructure may cause intermittent failures
- Very long input may be truncated or rejected depending on model token limits
