Author Builds OSV.dev Vulnerability Lookup Tool
5.8
A developer discovered the OSV.dev open CORS JSON API and had Claude Code build an HTML tool that accepts a pyproject.toml, requirements.txt, or a GitHub repository name to list reported vulnerabilities. The tool queries OSV.dev in-browser without a backend, returning dependency vulnerability reports. This enables quick client-side dependency scans during development.
Key Points
- 1Builds HTML tool using OSV.dev open CORS JSON API to report vulnerabilities from dependency files
- 2Demonstrates API's client-side accessibility, enabling direct browser queries without proxies or credentials
- 3Enables developers to quickly scan pyproject/requirements or repos for known vulnerabilities in-browser
Scoring Rationale
Useful, immediately usable tool with direct client-side scanning; limited novelty and single-source reporting reduces broader impact.
