Stack Facts EOL Check
x402
Stack Facts EOL Check is a paid API for AI agents from g5joilnmeep4ntz3nwezxt5dmu.srv.us, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).
Returns end-of-life status for one or more software packages, including EOL date, LTS info, latest version, and lifecycle metadata, with a signed cryptographic response paid per-call in USDC.

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 data array of results per queried package, each including found status, EOL date, LTS date, support-until date, days until EOL (negative if already EOL), latest version, release date, and lifecycle status label. Also includes unknown packages that could not be resolved. The meta block contains a cryptographic signature, key ID, data source attribution, snapshot ID, licence info, and timestamp for auditability.
Example use cases
Pre-install dependency EOL check
“Before I install these packages — nodejs 18.19.0 and python 3.9 — can you tell me if either of them has already reached end of life or is close to it?”
CI pipeline software lifecycle gate
“Check if our stack components — nodejs 18 and ubuntu 20.04 — are still supported and haven't hit end of life yet, so I know if we need to upgrade before shipping.”
Tech debt audit for legacy services
“I need to know the EOL status for ruby 2.7 and php 7.4 — are they past end of life, when did support end, and what's the latest version I should be on?”
Technical details
Endpoint
GEThttps://g5joilnmeep4ntz3nwezxt5dmu.srv.us/v1/eol/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically signed, pay-per-call EOL lifecycle data with no API key or account setup required — ideal for AI agents that need trustworthy, verifiable answers about software support status. Prefer this over free ad-hoc lookups when auditability (signed responses) and multi-package batch checks matter, and when integrating into automated pipelines that need to handle USDC micropayments via x402.
Side effects
- Package name not recognized — returned in the unknown array with unknown_count incremented
- Empty or too-short items query param (minLength: 3) — likely 400 validation error
- Payment not received — 402 Payment Required before response is served
- Stale data flag in meta when snapshot is outdated
- Signature verification failure if response is tampered in transit
