Software version & end-of-life API latest stable, instantly.

The latest stable version and end-of-life dates for languages, runtimes, frameworks, databases and OSes.

The call

Keyless over MCP, or one REST call with a free key. Every datapoint is provenance-stamped and citeable.

# REST (free key)
curl -H "X-API-Key: $KEY" "https://dynamicfeed.ai/versions?product=python"

# MCP (keyless) — point any client at https://dynamicfeed.ai/mcp, then call:
software_version(product="python")

Sample response

{ "product": "python", "latest": "3.13.4", "eol": "2029-10-01",
  "released": "2026-04-08", "observed_at": "2026-06-02T00:00:00Z" }

Why live data

New releases ship weekly; a model's 'latest version' is stale the day it's trained. This serves the current stable + EOL so an agent never recommends a dead or wrong version.

Use it for

• DevOps and upgrade-advisor agents
• Is-my-stack-supported checks
• Cross-reference with the CVE feed: current AND not exploited
