## 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 legal-402box-io-0e082073 -d '<json body>'
```

Example prompt: Can you put together a full audit readiness checklist and documentation requirements for my Solidity-based DeFi lending protocol — I want to know what test coverage I need and how to pick the right auditor before we launch next month?

## When to prefer this

Choose this endpoint when preparing a smart contract project for a formal security audit and needing structured, actionable checklists, documentation guides, and test coverage plans. Prefer this over generic legal or compliance endpoints when the specific goal is audit readiness rather than token classification, licensing, or terms of service drafting.

## Known failure modes

- Vague or missing message prompt returns a generic or unhelpful response
- Overly broad queries may produce non-specific checklists not tailored to the contract type
- Network or payment failure results in no response
- Rate limiting or quota exhaustion may cause request failure
- Gemini Pro model unavailability could cause success:false response

## How this service works

Create audit readiness checklists, documentation requirements, test coverage plans, and auditor selection criteria for secure launches

## Output

A structured agent response containing an audit readiness checklist, required documentation list, recommended test coverage areas, and criteria for selecting a smart contract auditor — returned as a text response from a Gemini Pro agent along with success status and timestamp.
