# Stack Facts EOL Lookup

> Stack Facts EOL Lookup is a paid API for AI agents from g5joilnmeep4ntz3nwezxt5dmu.srv.us, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-13).

Returns end-of-life lifecycle data for a software product, including support cycles, LTS status, and days until EOL, with cryptographically signed answers paid per call in USDC.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stack-facts-eol-lookup-78885b72
```

Example prompt: Can you check if Node.js 18 is still supported or if it's reached end of life, and tell me when the current LTS cycle expires?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
