How this service works
Pay-per-call verification and data APIs for autonomous agents: check packages, crawl permissions, sanctions lists, and products before acting. x402 v2, USDC on Base. No API keys, no signup — payment is the authentication.
Output
Returns a vulnerability assessment for the specified package including risk score, risk level (e.g. low/medium/high/critical), and details of any known CVEs or security advisories found in the package version. May include counts of vulnerabilities by severity.
Example use cases
Pre-install dependency safety check
“I'm about to install 'requests' version '2.28.0' from PyPI into our codebase — can you check if it has any known security vulnerabilities first?”
CI pipeline package audit
“As part of our build pipeline, check if the Go module 'github.com/gin-gonic/gin' has any reported vulnerabilities so we can block the build if it does.”
Vendor supply-chain vetting
“We're evaluating a new vendor who uses the Maven package 'org.apache.log4j:log4j' — can you scan it for known CVEs before we approve the dependency?”
Technical details
Endpoint
GEThttps://relay402.georgespring.workers.dev/api/package-vulns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a quick, pay-per-call vulnerability check on a specific package without managing API keys or subscriptions. It covers all major ecosystems (npm, PyPI, Go, Maven, crates.io, RubyGems, NuGet, Packagist) in one interface. Prefer this over OSV or Snyk integrations when you need zero-setup auth via x402 micropayment, or when running in an autonomous agent context where credential management is impractical.
Side effects
- Package name not found in the specified ecosystem — returns 404 or empty result
- Invalid ecosystem value — schema enforces enum, returns validation error
- Version string malformed or too long — schema enforces maxLength:64
- Payment not provided or insufficient — returns HTTP 402 requiring USDC payment on Base
- Network or upstream vulnerability database unavailable — returns 5xx error
- Package exists but has no vulnerability data — returns empty findings, not an error
