## 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 technical-design-word-frequency-analyzer-41b8c92f -d '<json body>'
```

Example prompt: Can you analyze the word frequencies in my technical design document? Here's the Markdown: '## Architecture
We use a microservices approach...
## Interfaces
REST APIs are exposed...
## Trade-offs
Latency vs consistency is a key consideration...'

## When to prefer this

Choose this endpoint when you need deterministic, reproducible word frequency counts from a technical design document in Markdown or plain text format, and you do not require generative AI summarization or semantic analysis. It is well-suited for vocabulary audits, terminology consistency checks, and keyword density reviews on documents up to 20,000 characters.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- Empty or missing text field — no output produced
- Non-text binary content submitted — processing fails
- Payment not included or insufficient USDC — 402 response returned
