Each product's `releases[]` carries per-cycle dates.\n\n## Access\nv1: `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}`.\nLegacy 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\").\n\n## Auth\nNone on either version.\n\n## Rate limits\nNone observed in headers.\n\n## Freshness\nv1 `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.\n\n## Known gaps\n- v1's unknown-product path (`/api/v1/products/notarealproduct123/`) is **`HTTP 404` with a full HTML error page** (`<title>Page not Found | endoflife.date</title>`), not JSON — a client parsing every response as JSON will throw on the 404 case specifically, even though every success path is clean JSON.\n- 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.\n- 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.\n\n## Probe log\n\n```\n$ curl -sS \"https://endoflife.date/api/v1/products/python/\" | python3 -m json.tool | head\n{\n    \"schema_version\": \"1.2.1\",\n    \"generated_at\": \"2026-10-05T00:08:51+00:00\",\n    \"last_modified\": \"2026-10-02T00:06:55+00:00\",\n    \"result\": {\"releases\": [\n      {\"name\": \"3.14\", \"isLts\": false, \"ltsFrom\": null, \"isEoas\": false,\n       \"eoasFrom\": \"2027-10-01\", \"isEol\": false, \"eolFrom\": \"2030-10-31\",\n       \"isMaintained\": true, ...}\n\n$ curl -sS \"https://endoflife.date/api/python.json\" | python3 -m json.tool | head\n[{\"cycle\": \"3.14\", \"releaseDate\": \"2025-10-07\", \"eol\": \"2030-10-31\",\n  \"latest\": \"3.14.8\", \"support\": \"2027-10-01\", \"lts\": false}, ...]\n\n$ curl -sS \"https://endoflife.date/api/fedora.json\" | python3 -c \"\nimport json,sys;
