• search_charts read-only

  Search the site's charts by topic or question (e.g. "bear markets", "Shiller CAPE", "Nasdaq 100 drawdown", "monthly seasonality"). Returns each chart's title, the question it answers, its page and the dataset path to pass to get_dataset.

  Parameters:

• get_dataset read-only

  Read one published dataset (the JSON behind a chart), e.g. "sp500/drawdowns", "sp500/pe", "ndx/forward-pe", "recessions". Rows can be filtered by `since`/`until` on their `date` (or `year`). A result is capped at about 60,000 characters: when a file is larger (long daily series), each array keeps its most recent rows and the cut is reported under `windowed`. Scalars and summary fields are always included.

  Parameters:

  • path (required) — string — Dataset path without /api/ and .json, as returned by search_charts.
  • tail — integer — Rows kept per array after filtering, from the end. By default every row is returned when the result fits; long daily series are cut to their most recent rows and reported under `windowed`.
  • since — string — Keep rows dated on or after this (YYYY-MM-DD or YYYY).
  • until — string — Keep rows dated on or before this (YYYY-MM-DD or YYYY).
