## 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 contract-eye-ai-contract-clause-analyzer-0090d37f -d '<json body>'
```

Example prompt: Can you analyze this contract text for risky or one-sided clauses? Here's the full agreement: [paste contract text]. I want to know the risk score, which clauses are flagged, and what changes I should ask for.

## When to prefer this

Choose this endpoint when you need automated, structured risk analysis of contract or legal agreement text before signing — especially when you want severity ratings, specific clause excerpts, and actionable modification suggestions. Ideal for freelancers, startups, or procurement workflows that need a fast, low-cost first-pass review without engaging a lawyer. Prefer this over generic LLM prompting when you need a consistent, structured output format with risk scores and categorized findings.

## Known failure modes

- Empty or missing contract text body results in an error response
- Extremely long contract text may exceed processing limits
- Malformed JSON body returns a validation error
- Payment failure or insufficient USDC balance prevents the call from completing
- Non-English contract text may produce lower-quality analysis

## How this service works

Pay $0.05 USDC, get a detailed risk analysis of any contract text. Flags risky, one-sided, or unusual clauses.

## Output

Returns a JSON object with an overall risk score (0-10), total clause count, number of flagged clauses, a plain-language summary, a list of findings each with category, severity level (e.g. critical/high/medium), the specific clause excerpt, an explanation of why it's risky, and a suggested modification. Also lists clauses deemed safe. Includes a disclaimer that results are for informational purposes only and not legal advice.
