Daily Stock Prices (EOD)

Name: Daily Stock Prices (EOD)
Creator: KeyVex

Daily end-of-day closing-price history for US-listed stocks, ETFs, and mutual funds — including delisted tickers, so historical analysis is survivorship-bias-free. Coverage reaches back as far as 1962 for the oldest names. Each row carries the as-traded close, the split- and dividend-adjusted close (chart this one), the dividend paid with that ex-date, and the split factor. The full requested window returns in one call; weekly/monthly downsampling keeps multi-year charts compact. Paid plans only. Close Prices from Tiingo.com.

What it returns

One call = one ticker. Use adj_close for charts and return calculations (as-traded close has artificial cliffs at splits). frequency=weekly|monthly returns the last bar per period with dividends summed and split factors compounded. History depth follows your plan: Pro = 5 years, Premium+ = full history. Unlike KeyVex's public-record datasets, this is licensed third-party market data — no bulk export, attribution required (Close Prices from Tiingo.com). See the live example below for the full field set.
