# Code Diff Security & Bug Reviewer

> Code Diff Security & Bug Reviewer is a paid API for AI agents from i3p3mgbsn54dvlivnk6wbumal40eqtsn.lambda-url.us-east-1.on.aws, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-10).

Analyzes a source-code diff for bugs, missing tests, compatibility problems, unsafe migrations, and security vulnerabilities, returning structured findings with file/line evidence and confidence scores.

## 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-diff-security-bug-reviewer-cdae9285 -d '<json body>'
```

Example prompt: Review this git diff for me — check for likely bugs, missing tests, unsafe migrations, and any security issues, and give me structured findings with file and line references and confidence scores.

## When to prefer this

Choose this endpoint when you need structured, evidence-backed code review focused specifically on diffs or patches — especially for catching security issues, unsafe migrations, and missing tests at the change level rather than auditing an entire codebase. Prefer it over generic static analysis when you want per-finding confidence scores and file/line traceability in a machine-readable format suitable for agentic workflows.

## Known failure modes

- Empty or malformed diff input returns a validation error
- Diff too large may exceed payload limits or timeout
- Non-code content (e.g. binary diffs) may produce no findings or an error
- Ambiguous context in a diff may result in low-confidence findings
- Rate limiting or payment failure returns a 402 or 429 error

## How this service works

Review a source-code diff for likely bugs, missing tests, compatibility problems, unsafe migrations, and security-relevant mistakes. Returns structured findings with file/line evidence and confidence.

## Output

Returns a structured JSON response containing a list of findings, each with: the affected file path and line number(s), a category (bug, security, missing test, compatibility, unsafe migration), a description of the issue, and a confidence score. Findings are prioritized by severity and confidence.
