All GET, anonymous,\n`api.stackexchange.com/2.3`.\n\n## The default filter omits `body` (and most of the catalog)\n\n```\n$ curl -s 'https://api.stackexchange.com/2.3/questions?order=desc&sort=activity&site=stackoverflow&pagesize=1'\n```\nreturns one question item with `tags`, `owner`, `is_answered`, `view_count`,\n`answer_count`, `score`, `last_activity_date`, `creation_date`, `question_id`,\n`content_license`, `link`, `title` — **no `body` field at all**, plus the wrapper\n`has_more: true, quota_max: 300, quota_remaining: 297` (confirms quota_max appears\non this envelope too, not just the ones in the existing record).\n\n## `filters/create` with `base=default` returns a cross-type superset, not a scoped filter\n\n```\n$ curl -s 'https://api.stackexchange.com/2.3/filters/create?include=question.body&base=default&unsafe=false'\n```\nreturns `filter_type: \"safe\"`, `filter: \"!SyjNqbwGU2NWZ1zo9n\"`, and an\n`included_fields` array of **over 300 entries spanning every object type** —\n`answer.*`, `article.*`, `badge.*`, `comment.*`, `question.*` (now including\n`question.body`), `site.*`, `user.*`, etc. — not just fields relevant to\n`question`. A client expecting `base=default&include=question.body` to hand back\na question-scoped field list gets the whole catalog's safe fields instead.\nApplying the returned filter does add the requested field:\n```\n$ curl -s 'https://api.stackexchange.com/2.3/questions/42876210?site=stackoverflow&filter=!SyjNqbwGU2NWZ1zo9n'\n```\n→ `question.body` present, 580 characters, confirming the filter works even\nthough its `included_fields` listing is far broader than the one type touched.\n\n## `/sites` is rate- and page-gated exactly like content endpoints\n\n```\n$ curl -s 'https://api.stackexchange.com/2.3/sites?pagesize=3&page=1'\n```\n→ 200, `has_more: true, quota_max: 300, quota_remaining: 295` — same envelope\nshape as `/questions`.
