What's inside an ETF or mutual fund, from its latest SEC N-PORT filing

What's inside an ETF or mutual fund, from its latest SEC N-PORT filing. Pass an ETF/fund ticker (SPY, ARKK) or CIK in the path. Returns the registrant, net/total assets, report date, and every portfolio holding by value — name, CUSIP, ISIN, shares, USD value, % of net assets, asset/issuer class, country. `?limit=` (max 500). Fund composition the 13F feed doesn't cover. From x402stock
