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 the product label, an array of release cycles each containing EOL date, LTS date, latest version, support status, days until EOL, and release date. Metadata includes a SHA-256 hash, cryptographic signature, source attribution, snapshot ID, and a staleness flag so the agent can verify data integrity and freshness.
Example use cases
Pre-install dependency check
“Before I add Python 3.9 to my new project, can you check whether it's still supported or if it's end of life, and when support ends?”
CI pipeline version audit
“I need to know the full lifecycle status of Node.js 20 — is it LTS, what's the latest patch version, and how many days until it goes end of life?”
Security posture review
“We're auditing our stack — can you pull the end-of-life data for Ubuntu 20.04 so I know if we're still within the supported window?”
Technical details
Endpoint
GEThttps://g5joilnmeep4ntz3nwezxt5dmu.srv.us/v1/eol/%7Bproduct%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically signed, pay-per-call EOL lifecycle data for a software product without managing API keys or subscriptions. Ideal for AI agents that need verifiable, tamper-evident lifecycle data — especially in security audits, dependency checks, or compliance workflows where data provenance matters. Prefer over free alternatives when auditability and signed responses are required.
Side effects
- Unknown product name returns empty cycles array or 404
- Stale data indicated by meta.stale=true when upstream endoflife.date has not been refreshed
- Payment failure (402) if USDC balance is insufficient
- Invalid product slug may return no matching data
- Network timeout on slow connections
