## 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

## When to prefer this

Choose this endpoint when you need fast, pay-per-call AI keyword extraction without a subscription — ideal for sporadic or burst workloads. It's part of a larger AI content suite (Tempest), so it's well-suited for pipelines already using other Tempest endpoints. Prefer it over general LLM prompting when you want a structured, predictable response format for keywords with controllable count.

## Known failure modes

- Empty or missing `text` field returns an error or empty result
- Very short input text may yield fewer keywords than requested via `count`
- Non-English text may produce lower-quality keyword extraction
- Extremely long text may exceed token limits or slow response
- Invalid `count` value (e.g. negative number) may cause a 400 error
