The files

Buffer ETFs funds.json Every defined outcome ETF with its published terms and current figures: reference index, buffer, cap, outcome period, index and fund return, remaining cap and downside before the buffer as the issuer publishes them, plus the ETFIQ fields (protection left in index points, buffer used, state). ETFIQ's figures and issuer data: index.json names which fields are ETFIQ's.

Buffer ETFs by outcome period buffer-periods.json Every buffer ETF in one of four groups by the length of its outcome period: annual, quarterly, monthly and laddered. Each laddered fund carries its sleeves at the weights its own Form N-PORT gives, each sleeve's issuer figures, and ETFIQ's weighted cap left, fall before the buffers, protection left and days to the next reset; each monthly fund carries the terms its own prospectus states and the filing they were read from. Rebuilt every trading night. ETFIQ's figures and issuer data: the file names which fields are ETFIQ's.

Income ETFs income.json Every option-income ETF with price, cash distributions and total return over 3 months, 6 months, 1 year, 3 years and since launch, each against its benchmark, with payout frequency, annualized payout rate, trailing twelve month cash and the prospectus expense ratio. ETFIQ's figures and issuer data: index.json names which fields are ETFIQ's.

Thematic ETFs thematic.json Every thematic ETF with its holdings summary, weight already in the S&P 500 and the Nasdaq-100, active share, top ten weight, returns against both indexes, drawdown, fee and active expense ratio, plus a fund-to-fund overlap matrix. ETFIQ's figures and issuer data: the file names which fields are ETFIQ's.

Payout calendar payouts.json Declared, scheduled and estimated distributions per fund, with ex and pay dates, the cadence and the ex-to-pay lag. ETFIQ's figures and issuer data: index.json names which fields are ETFIQ's.

Leveraged ETFs leverage.json Every leveraged and inverse ETF with its stated multiple, the underlying it is levered on, what it returned over each window, what its stated multiple would have produced over the same days, the difference between the two, and the underlying's volatility. Funds in a group sold by more than one issuer also carry the group's shared window. ETFIQ's figures and issuer data: the file names which fields are ETFIQ's.

Return of capital sources.json Issuers' own Rule 19a-1 estimates of what each distribution was made of, with the notice it came from. ETFIQ's figures and issuer data: index.json names which fields are ETFIQ's.

What changed insights.json The computed lines published each trading night, one per finding, with the fund's category and a link. Computed by ETFIQ.

Crypto ETFs crypto.json Every US listed spot crypto ETP with the coin it holds, what the fund returned and what the coin did over exactly the same two trading dates, the difference in percentage points, the compounded gap that is right where the subtraction is not, and how many days the fund closed unchanged. ETFIQ's figures and issuer data: the file names which fields are ETFIQ's.

Crypto ETF terms crypto-terms.json The sponsor's fee, the fee waiver and when it ends, whether the trust stakes, and net assets as of its last balance sheet, for every US listed spot crypto ETP, each with the 10-K, S-1 or 424B3 it was read from. These trusts file no prospectus XBRL, so none of this exists in a structured field anywhere: it is read from the sentence in each filing that states it, and a figure that cannot be checked against the fund's own share count and share price is published as unread rather than estimated. Issuer data, credited to its source.

Alternatives ETFs alternatives.json Every alternatives ETF with the strategy read from its own prospectus and the filing it was read from, 52 weeks of correlation and beta against the S&P 500 (through SPY), the fund's and SPY's average return in the weeks SPY fell and the down-week capture that is their ratio, the fund's total return against BIL over the same weeks, returns against SPY over each window, and the prospectus expense ratio. ETFIQ's figures and issuer data: the file names which fields are ETFIQ's.

Category scores scores.json One score per fund for its own category, each a percentile of a single published figure inside a stated set, with the components, the weights where a score blends two, the raw figure behind each component and the size of the set. No composite across categories. ETFIQ's figures and issuer data: the file names which fields are ETFIQ's.

ETF screener screener.json One row per covered ETF: fee, net assets, total return over 1 month, 3 months, 1 year and since launch, the 12-month yield, the IQ score where the fund has one, holdings count and top ten weight, money in or out over a day, a week and a month, and the measures its own category adds (protection left and cap left for a buffer ETF, payout coverage for an income ETF, share in the S&P 500 for a theme ETF, gap to the daily multiple for a leveraged ETF, coin capture for a crypto ETF, rate cushion for a bond ETF). Every figure has its own date beside it; a value a fund does not have is null, never zero. Also as CSV at /data/screener.csv. ETFIQ's figures and issuer data: the file names which fields are ETFIQ's.

Look-through books books/index.json An index of the filed holdings book held for each fund, with its as-of date and whether the fund is synthetic. Each fund's book sits at /data/books/ under its ticker in lower case: /data/books/spy.json for SPY. Each book is its issuer's data, labelled with its source.

Categories categories.json Where each fund outside the specialist categories sits: Stocks, Bonds, Commodities or Allocation, then its group and segment, or the specialist category that claims it. Per fund: category, group, segment, status, the rule that placed it, the reason in one sentence, the evidence with the filing each fact was read from, and what is still missing. Every placement is ETFIQ's own, computed from the fund's filings. Rebuilt when it goes stale, at most once a week. Computed by ETFIQ.

Bond funds bonds.json What each bond and cash fund holds, read from its latest Form N-PORT: duration in years and how it was measured, maturity buckets, the mix of Treasury, agency, corporate, securitized, municipal, foreign government and cash, how much of its credit-spread risk is high yield, the defaulted and in-arrears shares, net assets, and the filing with its report date. Rebuilt every trading night. ETFIQ's figures and issuer data: the file names which fields are ETFIQ's.

ETF issuers ranked by assets issuers-league.json Every ETF issuer ETFIQ covers, ranked by the net assets of its ETFs: the sum of each ETF's latest net assets figure with the first and last day those figures are dated, its share of the covered total, its ETF count, the change in net assets over one month, net flows over one week, one month and the year to date where ETFs have daily figures, the year of monthly flows from SEC Form N-PORT, and the average fee weighted by net assets. The same rows are at /data/issuers-league.csv. Computed by ETFIQ.

Fund flows: coverage flows/index.json Which funds have flows and how they are counted: daily from each issuer's own figures, or monthly from SEC Form N-PORT, with each fund's first and last dated figure, the coverage by category and issuer as a share of assets, the sources with the days they reach, and each window's first and last day. Each fund's daily and monthly flows, its window totals, weeks and months are one file at /data/flows/funds/ticker.json, the ticker in lower case. Computed by ETFIQ from each fund's change in shares outstanding times the previous day's NAV; the issuers' share counts and NAVs themselves stay private. Computed by ETFIQ.

Fund flows: by category and issuer flows/aggregates.json Net flows over 1 day, 1 week, 1 month, 3 months, year to date and 1 year for every category, segment and issuer: each total with the part that is round trips, the funds it counts, how many have every day of the window and their share of assets, the 25 largest inflows and outflows of each window, and the groups with a flows page of their own. Rebuilt every trading night. Computed by ETFIQ.

Income ETFs against a listed stock stock-pairs.json Each income ETF ETFIQ compares with a listed stock readers weigh it against, and the stock's price change, dividends and total return over exactly the days of each of the fund's own windows, with the fund's weight in the stock by its own holdings. The stock is not the fund's benchmark. Computed by ETFIQ from Tiingo daily prices. ETFIQ's figures and issuer data: the file names which fields are ETFIQ's.

ETF screener table screener-table.json Every row of the ETF screener's pages, in their order (largest net assets first), with the page each fund is on and each cell exactly as the pages print it, the sort value of each figure, and the values the screener's filters read, copied from screener.json, where each figure has its date. ETFIQ's figures and issuer data: the file names which fields are ETFIQ's.

Page index page-index.json Every page ETFIQ publishes other than the comparisons of two funds: its address, type, title, h1, description and dated lead sentence as published, the entities it is about, and the plain phrasings a reader types for it, written by rule per page type. Read by Ask IQ's find_page tool and the homepage box. Computed by ETFIQ.

Page index, comparisons page-index-pairs.json Every published comparison of two ETFs: its category, the two tickers and whether it is listed for search. Computed by ETFIQ.

Benchmarks for model portfolios benchmarks.json The ETFIQ benchmarks for model portfolios: each one's weights, rule and freeze date, and its returns, volatility, drawdown, Sharpe ratio, turnover, factor loadings and weighted expense ratio over each window, each figure with its dates and its basis (hypothetical before the freeze, tracked from it).

Whose figures these are

Each file says what it holds: figures ETFIQ computes, data an issuer published, or both, in which case it lists which fields are which. Each issuer holdings file under /data/books/ is labelled with its source and stays under its owner's terms. The full terms are at Licence.

Method

Terms come from issuer product pages and prospectus supplements filed with the SEC. Prices and distributions come from exchange end-of-day data. Holdings come from Form N-PORT and, where an issuer publishes one, its daily file. Fees come from the prospectus risk and return data filed as XBRL. Every figure ETFIQ computes rather than quotes is marked on the page and described on Standards. Each published number is recomputed from the raw sources every night by separate code, and anything that does not reproduce is listed before the site is published.

Building on it

index.json is the machine-readable manifest: every file with its address, its as-of date, its record count, its size, and every field with how many records actually carry one. That last part is the thing worth reading before you write against a field, because a fund with no expense ratio and a fund whose ratio nobody has read look the same in the file and different in the manifest. The addresses do not move, the files are served with permissive CORS and an ETag, and they change once a trading night. An assistant can ask for the same figures through the ETFIQ MCP server.

Fair use

The files are served from a static host with no rate limit and no key. Please cache rather than fetch repeatedly; they change once a night.
