# Stack Facts EOL Snapshot

> Stack Facts EOL Snapshot is a paid API for AI agents from g5joilnmeep4ntz3nwezxt5dmu.srv.us, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-13).

Returns a signed, cryptographically verifiable snapshot of end-of-life data for all tracked software products, sourced from endoflife.date, 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-snapshot-e4bc8019
```

Example prompt: Pull the latest end-of-life snapshot from Stack Facts so I can see which software products and versions have reached end-of-life, and give me the signed manifest so I can verify the data is authentic.

## When to prefer this

Choose this endpoint when you need a complete, verifiable snapshot of end-of-life status across all tracked software products in a single call, with cryptographic proof of data integrity (signed manifest + SHA-256). Prefer it over scraping endoflife.date directly when you need tamper-evident, machine-readable data with provenance for security pipelines, compliance checks, or agent-driven dependency audits. Best suited for scenarios where you need the full EOL dataset rather than a single-product lookup, and where you want pay-per-call access without an API key or account.

## Known failure modes

- Payment not received or insufficient USDC — returns HTTP 402 Payment Required
- Upstream endoflife.date data temporarily unavailable — snapshot may be stale (meta.stale: true)
- Invalid or missing x402 payment header — request rejected before data is returned
- Network timeout reaching the service endpoint — no response
- Signature verification failure on client side if canonical JSON was modified in transit

## 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: a full snapshot of end-of-life records for all tracked software products (including lifecycle cycles per version), a cryptographically signed manifest with SHA-256 hash, snapshot ID, fetch timestamp, record count, licence (MIT, attributed to endoflife.date), source URL, and metadata fields indicating staleness and the upstream schema version. The 'verify' field provides a SHA-256 of the canonical JSON for independent integrity checking.
