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.
Example use cases
PR security audit before merge
“Can you analyze this pull request diff for security vulnerabilities and risky patterns before I merge it into main? I want structured findings with file and line numbers and how confident you are about each issue.”
Database migration safety check
“I've got a diff for a new database migration script — can you review it for unsafe changes, missing rollback logic, or compatibility problems with the existing schema?”
Bug detection in feature branch diff
“Here's the diff for a new feature I wrote — please check it for likely bugs, any missing test coverage, and anything that might break compatibility with the current codebase.”

Endpoint
POSThttps://i3p3mgbsn54dvlivnk6wbumal40eqtsn.lambda-url.us-east-1.on.aws/v1/code-diff-verifier?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
