## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 24k-labs-keywords-extract-a5755155 -d '<json body>'
```

Example prompt: Can you pull out the key topics, entities, and tags from this article text and give me a ranked list? Here's the text: 'The Federal Reserve raised interest rates again amid persistent inflation concerns, with Chair Jerome Powell signaling further hikes could follow if economic data warrants.'

## When to prefer this

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.

## Known failure modes

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