The NIRISS single-object slitless spectroscopy mode measures time-series spectra from $0.6$ to $2.8\,\mu\mathrm m$. It supports <exoplanet transmission spectra> and eclipse observations, as described in https://jwst-docs.stsci.edu/jwst-near-infrared-imager-and-slitless-spectrograph/niriss-observing-modes/niriss-single-object-slitless-spectroscopy[the instrument guide].
