## 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 smart-contract-risk-summarizer-9dfec0ed -d '<json body>'
```

Example prompt: Can you analyze this Solidity smart contract and give me a plain-English risk assessment — flag any dangerous patterns, tell me the overall risk level, and summarize the key findings? Here's the source code: [paste Solidity code here]

## When to prefer this

Choose this endpoint when you need a fast, structured, machine-readable risk assessment of Solidity smart contract source code without setting up a full local static analysis toolchain. It is ideal for AI agents doing automated due diligence, developer tools that need to surface risk signals inline, or any workflow where plain-English output is required alongside structured findings. It is not a replacement for a comprehensive formal audit but is well-suited for rapid screening and triage.

## Known failure modes

- Source code exceeds 50,000 character limit — returns a 400 error
- Malformed or non-Solidity input — may return a generic or low-confidence assessment
- Payment not fulfilled via x402 — returns 402 Payment Required
- Service temporarily unavailable — returns 5xx error
- Empty or whitespace-only source code submitted — likely returns validation error

## How this service works

Plain-English smart-contract risk summarizer: submit Solidity source code (max 50000 chars) and get back a structured risk assessment (risk level, specific findings, plain-English summary) - callable by a dev tool or an agent doing due diligence, not just a human reading a dashboard. Priced at $0.001/KB (min $0.01).

## Output

A structured JSON object containing a risk level (e.g. low/medium/high/critical), a list of specific findings describing dangerous or suspicious patterns found in the code, and a plain-English summary of the overall risk assessment suitable for both technical and non-technical readers.
