Spark API: close-price series

Parameters

symbols
querystringrequired
Comma-separated symbols, up to your plan's symbols-per-request (50 at most).
interval
querystring
Bar size: 1m, 2m, 5m, 15m, 30m, 60m, 90m, 1h, 1d, 5d, 1wk, 1mo or 3mo. 60m and 1h are the same bars.
Default: 1d
range
querystring
1d, 5d, 1mo, 3mo, 6mo, 1y, 2y, 5y, 10y, ytd, max, or any N followed by d, wk, mo or y. Nd counts trading sessions; mo, y and ytd are calendar arithmetic in the exchange's timezone.
Default: 1mo

Behavior

  • The response is a plain object keyed by symbol, each with timestamp[] and close[], with no envelope. Symbols with no data are omitted rather than nulled.
  • Unlike the quote endpoint, a malformed symbol refuses the whole request with a 400 naming it.
  • Intervals, ranges, sessions and chartPreviousClose follow the chart endpoint; there is no period1/period2 here.
  • 50,000 bars in total across the request; more is a 400 naming the levers (a shorter range, a coarser interval, fewer symbols), never a shortened series.
