## When to prefer this

Choose this endpoint when you need fast, affordable, plain-language explanations of concepts at high volume — e.g. building glossaries, educational tools, or chatbot FAQ systems. Prefer it over general-purpose LLM inference endpoints when you specifically need concept simplification without managing prompts yourself.

## Known failure modes

- Missing 'concepto' query parameter returns a validation error
- Empty or ambiguous concept string may yield a generic or unhelpful response
- Rate limiting may occur under extremely high concurrent volume despite high-volume design
- Non-Spanish or very niche concepts may yield lower-quality explanations depending on underlying model
