# Solidity Security Scan: AI First

> Solidity Security Scan: AI First is a paid API for AI agents from emberagent.uk, paid per call via x402, $0.09/call, status unknown (last checked 2026-10-28).

Analyzes Solidity smart contract source code and returns a structured JSON security review with findings, severity levels, SWC categories, exploit explanations, fixes, and an overall risk level.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 solidity-security-scan-ai-first-169bf7e3 -d '<json body>'
```

Example prompt: Can you run a security scan on this Solidity contract and give me a JSON report with findings, their severity, SWC categories, and suggested fixes? I'm especially worried about reentrancy and ownership centralization risks.

## When to prefer this

Choose this endpoint when you need a fast, structured, machine-readable first-pass security review of Solidity smart contract code — especially for automated pipelines, CI/CD integration, or pre-audit triage. It is distinct from generic code review tools because it returns SWC-categorized findings, rug-pull and centralization risk analysis, and exploit explanations specific to smart contracts. Prefer it over manual review for rapid iteration and over general static analyzers when you need natural-language exploit explanations and fixes in JSON format.

## Known failure modes

- Malformed or non-Solidity input causes parsing failure or generic error response
- Missing imports beyond standard OpenZeppelin may produce incomplete analysis
- Very large contracts may hit input size limits
- AI may produce false positives or miss subtle logic bugs — not a substitute for professional audit
- Network or payment failure returns HTTP 402 or 5xx error

## How this service works

Send Solidity source code; get a structured JSON security review: findings with severity, SWC/category, location, exploit explanation and fix, plus centralization/rug-pull powers and an overall risk level. Automated first pass by an AI agent, not a substitute for a professional audit.

## Output

A structured JSON object containing: a list of security findings each with severity (critical/high/medium/low/informational), SWC ID or category, file/line location, exploit explanation, and recommended fix; a section on centralization and rug-pull risks; and an overall risk level for the contract.

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "input": {
   "type": "string",
   "description": "Solidity source code as plain text (one or more contracts). Optional first line 'focus: <topic>' (e.g. 'focus: reentrancy' or 'focus: token rug risks'). Missing imports are assumed to be standard OpenZeppelin."
  }
 }
}
```

## Response schema (JSON Schema)
