Check whether a specific version of a software product is end-of-life (EOL). Returns lifecycle status, the EOL date, days remaining or days past EOL, and the latest release. Use this for "is X version Y still supported?" questions.

Get the proprietary EOL Risk Score™ (0–100) for a product version, with the four-factor breakdown (EOL recency, attack surface, CISA KEV exposure, extended support). Omit "version" to score the product's highest-risk (most recently end-of-lifed) release. Use this to quantify how dangerous it is to keep running something.

Audit a whole stack at once. Provide a list of products (optionally with versions) — e.g. parsed from a package.json, Dockerfile, or SBOM — and get an EOL Risk Score for each, so you can see what is unsupported and dangerous in one call. Free tier: up to 5 items; Pro: up to 50.

List or search the products endoflife.ai tracks (480+). Pass an optional "query" substring to find the canonical slug for a product before calling the other tools (e.g. "postgres" → "postgresql"). Returns matching product slugs.

Get the full version history for one product: every tracked version/cycle with its release date, EOL date, support status, and EOL Risk Score™. Use for "give me the whole EOL schedule for X".
