## 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 agentbit-content-keywords-extractor-3a16067d -d '<json body>'
```

Example prompt: Pull out the top 15 keywords from this article text so I can tag it properly: [paste article here]

## When to prefer this

Choose this endpoint when you need fast, pay-per-call keyword extraction from arbitrary text without signing up for an NLP platform. It's ideal for agents processing one-off documents, articles, or user-submitted content where a full NLP subscription would be overkill. At $0.002 per call with no API key required, it's well-suited for low-volume or sporadic keyword extraction tasks in automated pipelines.

## Known failure modes

- Text exceeds 100,000 character limit — request rejected
- Limit parameter out of range (must be 1–50) — validation error
- Empty or missing text field — returns error
- Payment not completed via x402 — 402 Payment Required response
- Malformed JSON body — 400 Bad Request
