Same host rules as `companyfacts`: no key, a declared `User-Agent` with contact is mandatory (403 `text/html` without), CIK paths are `CIK` + 10-digit zero-padded.\n\n## Period grammar — observed 2026-09-30\n- `us-gaap/Assets/USD/CY2024Q1I.json` → **200**, `{taxonomy, tag, ccp: \"CY2024Q1I\", uom: \"USD\", label, description, pts: 5849, data: [{accn, cik: 1750, entityName, loc: \"US-IL\", end: \"2024-02-29\", val: 2021800000}, ...]}`. Note `cik` in the body is an **integer** (1750), not the padded string used in paths.\n- `us-gaap/Assets/USD/CY2024Q1.json` (instant concept, no `I`) → **404**.\n- `us-gaap/Revenues/USD/CY2024.json` (duration concept, no `I`) → **200**, `pts: 2503`, rows carry `start` and `end` (`\"2024-01-01\"` … `\"2024-12-31\"`).\n- `us-gaap/Revenues/USD/CY2024I.json` (duration concept with `I`) → **404**.\nSo: balance-sheet (instant) concepts take `CY####Q#I` / `CY####I`; income/cash-flow (duration) concepts take `CY####` / `CY####Q#`. The wrong suffix is not \"empty\", it is \"not found\".\n\n## Unit spelling\n- Path `us-gaap/EarningsPerShareBasic/USD-per-shares/CY2024.json` → 200 with body `uom: \"USD/shares\"`. The path spells `/` as `-per-`; the body returns the XBRL form.\n- Path `.../Assets/usd/CY2024Q1I.json` (lowercase unit) → **404**. Case-sensitive.\n\n## The 404 shape — observed 2026-09-30\nEvery miss — wrong period suffix, unknown tag (`NotATag`), lowercase unit, **unpadded CIK** (`companyfacts/CIK16918.json`, `submissions/CIK16918.json`), and a well-formed but nonexistent CIK (`companyfacts/CIK0009999999.json`) — returns the identical **HTTP 404 `application/xml`**:\n```\n<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<Error><Code>NoSuchKey</Code><Message>The specified key does not exist.</Message><Key>api/xbrl/frames/us-gaap/Assets/USD/CY2024Q1.json</Key><RequestId>...</RequestId><HostId>...</HostId></Error>\n```\nThis is an object-store (S3-style) listing miss, not an API error: there is no JSON, no hint about *which* segment was wrong, and \"does not exist\" cannot distinguish a typo from a company with no XBRL. The only useful field is `<Key>` — it echoes the path you asked for, so you can check padding/case/suffix against it.\n\n## Adjacent, same host (observed 2026-09-30)\n`GET /submissions/CIK0000016918.json` → 200 with entity metadata (`cik`, `tickers[]`, `exchanges[]`, `ein`, `lei`, `fiscalYearEnd`, `formerNames[]`) and `filings.recent` as **column-oriented parallel arrays** (`accessionNumber[]`, `filingDate[]`, `form[]`, `primaryDocument[]`, `isXBRL[]`, … — 16 arrays, 1003 entries each here); older filings are not in the body but named in `filings.files[]` (`{name: \"CIK0000016918-submissions-001.json\", filingCount: 1457, filingFrom: \"1994-01-13\", filingTo: \"2018-03-27\"}`), fetched from the same `/submissions/` prefix.
