How this service works
Dependency intelligence for AI coding agents, paid per-call via x402 (USDC on Base): npm package health scores with a disclosed rubric, typosquat checks, dependency audits, OSV known-vulnerability scans (npm, PyPI, Go, crates.io, Maven and more) and PyPI preflight checks. Free index at /, free sample at /api/sample.
Output
Returns a JSON object with a summary containing counts of audited, clean, lookalike, not-on-PyPI, and vulnerability-affected packages, plus a human-readable verdict string (e.g. 'STOP: requirements name projects that do not exist on PyPI') indicating whether the package list is safe to install.
Example use cases
AI-generated requirements safety check
“My coding agent just generated a requirements.txt with these packages: langchain==0.1.0,openai,tiktoken,pydantic,fstapi — can you verify they all actually exist on PyPI and flag any that look like typosquats or hallucinations?”
Pre-install vulnerability scan
“Before I install these Python packages in my project, check them for known security vulnerabilities and tell me if any have CVEs I should know about: pillow==9.0.0,urllib3==1.26.4,paramiko”
CI pipeline dependency gate
“I want to block our deployment if any of our Python dependencies are flagged as unsafe — can you audit this list and give me a stop-or-go verdict: boto3,django==4.2.0,psycopg2-binary,cryptography==38.0.0?”
Technical details
Endpoint
GEThttps://pkgpulse.letom1176.workers.dev/api/pypi-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate Python (PyPI) package dependencies specifically — especially when packages were generated by an AI coding agent and may be hallucinated, or when you want a combined typosquat + vulnerability + existence check in a single call before running pip install or updating a requirements.txt file. Prefer it over generic OSV scanners when you need the hallucination/existence check bundled with security scanning.
Side effects
- Missing 'names' query parameter returns an error
- Non-existent or misspelled package names are flagged as not_on_pypi
- Payment not included or invalid x402 USDC payment results in 402 Payment Required
- Rate limiting or Cloudflare Worker timeout for very large package lists
- OSV database unavailability may cause incomplete vulnerability results
