## 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-document-length-and-paragraph-profile-b6aa1a1f -d '<json body>'
```

Example prompt: Can you run a length and paragraph profile on my technical design document? Here's the content: '## Architecture
We use a microservices approach...

## Interfaces
REST APIs are exposed...

## Trade-offs
Latency is a concern...'

## When to prefer this

Choose this endpoint when you need a fast, deterministic, reproducible structural analysis of a technical design document's length and paragraph characteristics — not AI-generated summaries or rewrites. Ideal for document quality pipelines, pre-review checks, or automated documentation audits where consistent, rule-based metrics are required rather than generative output.

## Known failure modes

- Input text exceeds 20,000 character limit — request is rejected
- Empty or missing text field — no profile can be generated
- Malformed or non-textual input — unexpected metrics or error response
- Payment not processed or insufficient USDC balance — request blocked

## How this service works

Technical design - Length and paragraph profile: Length and paragraph profile for Technical design. Supplied Markdown or plain text, up to 20,000 characters. Deterministic processing and document templates; no generative prose or fact checking. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded length and paragraph profile deliverable.

## Output

Returns a deterministic length and paragraph profile for the submitted technical design document, including metrics such as total character/word counts, paragraph counts, section-level length breakdowns, and structural distribution data. No generative prose or AI-written content is included — all output is computed from the input text.
