Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/keywords-extractWhen to prefer
Choose this endpoint when you need a quick, ranked extraction of key topics, entities, and tags from arbitrary text without building a full NLP pipeline. It is well-suited for content tagging, SEO keyword generation, document indexing, and summarizing research or articles. Prefer it over a full LLM call when you want a structured, ranked keyword list at low cost ($0.006 per call) with fast latency.
Side effects

- Non-English text may produce degraded extraction quality if multilingual support is limited
- Overly long text may be truncated or return a timeout
