# Stack Facts EOL Lookup – End-of-Life Status for Software Products

> Stack Facts EOL Lookup – End-of-Life Status for Software Products 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, support, and lifecycle dates for a specific software product and release cycle, 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-end-of-life-status-for-software-products-3f180a1e
```

Example prompt: Can you check if Python 3.12 has reached end-of-life yet, and tell me when its security support ends?

## When to prefer this

Choose this endpoint when you need authoritative, cryptographically signed EOL and lifecycle data for a specific software product version — especially in security-sensitive or compliance contexts where data provenance matters. It is preferable to querying endoflife.date directly when you need signed, auditable answers with no account setup. Best for AI agents operating autonomously that need trustworthy per-call lifecycle data without maintaining API credentials.

## Known failure modes

- Unknown product or cycle returns a 404 or error response
- Stale data flag in meta.stale indicates cached data may be outdated
- Payment failure via x402 protocol results in 402 response before data is returned
- Malformed product/cycle path parameters may yield empty or error responses
- Signature verification failure may indicate tampered or invalid response

## 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

A JSON object containing the EOL date, support-until date, LTS flag, latest version, release date, days until EOL, and lifecycle status for the requested product and cycle, plus cryptographically signed metadata (SHA256 hash, signature, key ID, source attribution, snapshot ID, and retrieval timestamp) for auditability.
