  • marketSlugstring, required
  • intervalstring, default "1w"

    Window AND resolution: a shorter window returns finer points, so 1w gives far more detail than max. Use 1d or 1w to see how odds moved, max only for the coarse daily shape over the market's whole life.

    One of 1d, 1w, 1m, max

  • outcomestring

    e.g. Yes, No. Defaults to the first outcome
