Technical details
Endpoint
POSThttps://tanod.dev/v1/text/keywords?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, unsupervised keyphrase extraction without requiring a pretrained ML model or external language service. RAKE is deterministic, language-agnostic in approach, and works well on domain-specific or technical text. Prefer this over LLM-based keyword extraction when cost predictability and speed matter, or when you need structured keyphrase output in one of the seven supported European languages.
