# Code Security Scan API

> Code Security Scan API is a paid API for AI agents from scan-api-production-e73f.up.railway.app, paid per call via x402, $0.5/call, status unknown (last checked 2026-10-16).

Scans source code for security vulnerabilities using Semgrep, ESLint, Bandit, and npm audit, charged per scan via x402 micropayment.

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 code-security-scan-api-586c219f -d '<json body>'
```

Example prompt: Can you scan this JavaScript code for security vulnerabilities — here's the source and my package.json — and let me know what issues it finds?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use security scan of source code without committing to a subscription, especially when working with JavaScript, TypeScript, Python, or HTML. It is ideal for CI/CD pipelines, one-off code reviews, or agent workflows that need on-demand vulnerability detection across both static code analysis and dependency auditing in a single call.

## Known failure modes

- Payment not received or x402 payment fails — scan not executed
- Unsupported language detected or specified — scan may be skipped or return empty results
- Malformed or missing 'code' field — validation error returned
- Invalid package.json format — dependency audit skipped or error returned
- Scan timeout for very large code inputs
- Network or service unavailability on Railway deployment

## How this service works

Pay-per-scan code security scanning (Semgrep, ESLint, Bandit, npm audit) via x402.

## Output

Returns a structured report of security findings, including vulnerability descriptions, severity levels, affected lines or packages, and tool-specific results from Semgrep, ESLint, Bandit, and/or npm audit depending on the detected or specified language.
