P0 Package Risk & Vulnerability Lookup is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-30).
Returns known vulnerabilities (from OSV.dev) and OpenSSF Scorecard security data for a specific package version in a given ecosystem
An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 listings are not covered.
A JSON object containing: whether the package version is vulnerable, a list of vulnerability records from OSV.dev (with severity labels, source, and aliases), a count of records, the package verification status, an OpenSSF Scorecard with aggregate score (0-10) and individual check scores, the data timestamp, source URLs, and attribution information for all underlying data licenses.
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/package/risk?utm_source=zero.xyzUse this endpoint when you need authoritative, multi-source vulnerability data (OSV.dev aggregating GitHub Advisory, NVD, PyPI Advisory, RustSec, Go Vuln DB, etc.) plus OpenSSF Scorecard in a single call for a specific package version. Prefer it over generic web searches when you need structured, machine-readable security data with clear attribution and licensing. It covers npm, PyPI, Go, crates.io, RubyGems, Maven, and NuGet. Note: L402 listings are not included; this endpoint is specifically about package/dependency security risk, not agent service discovery.
