Stack Facts: Stack Watch – Package Security & Vulnerability Monitor
x402
Stack Facts: Stack Watch – Package Security & Vulnerability Monitor is a paid API for AI agents from g5joilnmeep4ntz3nwezxt5dmu.srv.us, paid per call via x402, $0.012/call, status unknown (last checked 2026-10-13).
Checks software packages, CVEs, and LLM prices for malware, known vulnerabilities (OSV), actively exploited CVEs (CISA KEV), and end-of-life status, returning cryptographically signed answers with a watch token for rechecks.

How this service works
Check a package before install: malware, known vulnerabilities (OSV), exploited CVEs (CISA KEV) and end-of-life, plus LLM prices; signed answers, pay per call in USDC, no account or API key.
Output
Returns a JSON object with a 'check' section summarizing EOL status, KEV matches, and CVE counts per item, plus a 'watch' section containing a signed token for future rechecks, a suggested_recheck_at timestamp, and per-dataset metadata including cryptographic signatures, SHA256 hashes, source URLs, and data freshness indicators.
Example use cases
Pre-install dependency security check
“I'm about to add react@18.2.0, axios@1.6.0, and webpack@5.88.0 to my project — can you check if any of them have known CVEs, are end-of-life, or show up in CISA's exploited vulnerabilities list before I run npm install?”
CVE exploitability triage
“We just got flagged on CVE-2021-44228 and CVE-2023-44487 — can you tell me if either of those is in the CISA Known Exploited Vulnerabilities catalog so I know which one to patch first?”
Scheduled stack health monitoring
“Set up a recurring watch on our production stack — nodejs@18.19.0, openssl@3.1.0, and pkg:npm/express@4.18.2 — and alert me if any become end-of-life or get added to the CISA KEV list within the next 90 days.”
Technical details
Endpoint
POSThttps://g5joilnmeep4ntz3nwezxt5dmu.srv.us/v1/stack/watch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically signed, authoritative vulnerability data combining OSV, CISA KEV, and end-of-life databases in a single call with no API key or account required — ideal for AI agents that need to pay per call in USDC, require signed audit-trail answers, or want to set up stateful monitoring via watch tokens. Prefer over raw CISA or OSV APIs when you need a unified, signed, pay-as-you-go response.
Side effects
- Invalid CVE format returns schema validation error
- Unknown or misspelled package name yields unknown_count increment with no match
- Expired or invalid watch token requires a fresh call without a token
- Payment not received results in HTTP 402 response requiring USDC payment
- Stale dataset indicated via meta.stale=true flag, results may be outdated
