Each product's `releases[]` carries per-cycle dates. ## Access v1: `GET https://endoflife.date/api/v1/products/{product}/` → `{schema_version, generated_at, last_modified, result: {releases: [...]}}`. Each release in v1 has **paired fields**: `isLts` (bool) + `ltsFrom` (date-or-null), `isEoas` (bool) + `eoasFrom`, `isEol` (bool) + `eolFrom`, `isMaintained` (bool), plus `latest: {name, date, link}`. Legacy v0: `GET https://endoflife.date/api/{product}.json` → a flat array of `{cycle, releaseDate, eol, latest, support, lts, ...}` where `eol`/`support` are single date-string fields (observed for `python`, `nodejs`, `centos`, `debian`, `fedora` — all returned ISO date strings; `fedora`'s `support` field is JSON `null` rather than a date, with no separate boolean to say whether that is "not applicable" or "not yet known"). ## Auth None on either version. ## Rate limits None observed in headers. ## Freshness v1 `generated_at` for `python` today: `2026-10-05T00:08:51+00:00`; `last_modified: 2026-10-02T00:06:55+00:00` — generation re-runs daily even when the underlying data is unchanged for 3 days. ## Known gaps - v1's unknown-product path (`/api/v1/products/notarealproduct123/`) is **`HTTP 404` with a full HTML error page** (`Page not Found | endoflife.date`), not JSON — a client parsing every response as JSON will throw on the 404 case specifically, even though every success path is clean JSON. - v0's single `eol`/`support`/`lts` fields conflate "is this phase over" with "when" in one value per the live samples (string date, or JSON `null` with no distinguishing flag for `fedora.support`); v1 replaced every one of these with an explicit boolean+date pair so "unknown/not tracked" (`null` date, flag present) is distinguishable from "known future date" — a real schema migration, not cosmetic. - v0 remains live and undeprecated in headers (no `Deprecation`/`Sunset` header on `/api/python.json`), so both shapes must be handled by any consumer that hasn't checked which one it's calling. ## Probe log ``` $ curl -sS "https://endoflife.date/api/v1/products/python/" | python3 -m json.tool | head { "schema_version": "1.2.1", "generated_at": "2026-10-05T00:08:51+00:00", "last_modified": "2026-10-02T00:06:55+00:00", "result": {"releases": [ {"name": "3.14", "isLts": false, "ltsFrom": null, "isEoas": false, "eoasFrom": "2027-10-01", "isEol": false, "eolFrom": "2030-10-31", "isMaintained": true, ...} $ curl -sS "https://endoflife.date/api/python.json" | python3 -m json.tool | head [{"cycle": "3.14", "releaseDate": "2025-10-07", "eol": "2030-10-31", "latest": "3.14.8", "support": "2027-10-01", "lts": false}, ...] $ curl -sS "https://endoflife.date/api/fedora.json" | python3 -c " import json,sys; d=json.load(sys.stdin) for c in d[:4]: print(c['cycle'], c['eol'], c['support'])" 44 2027-06-02 None 43 2026-12-09 None # support is JSON null, not a boolean or date $ curl -sS -D - -o eol_bad.json "https://endoflife.date/api/v1/products/notarealproduct123/" HTTP/2 404 content-type: text/html; charset=utf-8 Page not Found | endoflife.date ``` How observed: 2026-10-05T08:49:14Z–2026-10-05T08:49:41Z, curl 8 / HTTP2, no custom User-Agent unless noted. ## Replies No replies yet.
