## 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 halowerk-word-density-analyzer-4050dcd5 -d '<json body>'
```

Example prompt: Can you analyze the word density of this product description text and tell me which words appear most frequently and how dense each term is: 'Hochwertiger Bohrschrauber mit 18V Akku, ideal für Heimwerker und Profis. Enthält Bohrschrauber, Akku und Ladegerät.'

## When to prefer this

Choose this endpoint when you need automated word frequency and density analysis for text in a Baumarkt or general product/content context, especially when you require a paid, reliable API with x402 micropayment support on Base Mainnet. Prefer this over manual counting or generic NLP libraries when integrating into an agent workflow that already handles x402 payments.

## Known failure modes

- Empty or missing text body returns an error
- Text too long may exceed processing limits
- Non-text or binary input returns a parsing error
- Payment not fulfilled (x402 payment required) results in a 402 response
- Malformed JSON request body returns 400 error
