etf_searchFind US listed ETFs by ticker, fund name, or a word from the name. Use this FIRST when the user names a fund loosely, then etf_profile with the ticker it returns. Refuses rather than returning a near match.etf_profileEverything ETFIQ publishes about one fund: issuer, desk, and each figure with its source and as-of date, plus a one sentence verdict on how it did against what its own label promises.etf_holdingsWhat a fund holds, by weight, and how old that is. ALWAYS read lag_days before presenting it: an issuer file read today and a filing from two months ago both come back here and are not the same answer.etf_themeEvery US listed fund in a theme, largest first, with what each charges and how much of it is already in the S&P 500. USE THIS for any "what X ETFs are there" or "top X ETFs" question: it returns the whole published set rather than a sample.etf_themesEvery theme ETFIQ publishes and how many funds each holds. Call when unsure what a theme is called, then etf_theme.etfiq_pageRead ANY published ETFIQ page as text: a theme hub, a ranking, a comparison of two funds, an issuer, a methodology note, a dated study. Takes a path like /themes/cyber or a full etfiq.com URL. This reaches all 40,000 pages, including everything the typed tools above do not cover,etfiq_sectionsWhat ETFIQ publishes, section by section, with a page count for each. Start here when the question is not about one fund: it names every section and what is in it.etfiq_listThe pages inside one section, optionally filtered to those whose address contains a word. Use after etfiq_sections to find a page, then etfiq_page to read it. The count returned is the whole matching set even when the list is capped.etf_screenEvery fund matching some filters, largest first, each with its net assets and the source and date that figure came from. Use for "find me all X" questions rather than repeated searches. Fees are percentages, not basis points. Funds with no published size are set aside from a sizeetf_overlapHow much of their weight two funds hold in common, as ETFIQ published it on the comparison page for that pair. Use when asked whether two ETFs are the same thing, or whether owning both adds anything. Refuses rather than estimating when the pair is not compared or either holdingsetfiq_as_ofWhat ETFIQ published on a given date, from its frozen dated archive. Use when a question is about a past date, or when a figure needs to stay true after it is quoted: every other tool here answers about today and today moves overnight. Takes YYYY-MM-DD. Covers the pieces written etf_holdersWhich US listed ETFs hold a given company, ranked by how much of each fund it is. USE THIS for any "which ETFs hold X", "which fund holds the most X", or "how do I get exposure to X" question, where X is a company rather than a fund. Takes a company name or its ticker. Returns evetf_rankingsThe ranked lists ETFIQ publishes, or one of them. Each ranks ONE published figure inside a stated set: the cheapest funds in a theme, the leveraged funds furthest from their stated multiple, the buffer funds closest to their cap. Call with no argument for the list.Recent checks
