GET /fdsnws/dataselect/1/query

Request time series data (seismic waveforms) from the FDSN DataSelect Web Service. Returns actual seismic recordings in miniSEED format, a compact binary format optimized for seismic data. This is the primary endpoint for downloading raw waveform data for analysis. The response is binary miniSEED data, not text or JSON. Important: As of 2023, this service redirects to EarthScope (service.earthscope.org). Use this when you need actual seismic waveforms for processing, visualization, or research. The miniSEED format contains time-stamped amplitude values sampled at the station's sampling rate.
