Seismic Channel Metadata for a Station (EarthScope FDSN)

earthscopefdsnws/channels

Seismic channel metadata from the EarthScope Consortium FDSN station service for one station: each channel epoch with location code, channel code, coordinates, depth, azimuth, dip, sensor description, scale, sample rate and start and end times. Needs a network and a station code, and can narrow to a channel code such as BH?. At most 200 rows are returned, open and newest epochs first, with a flag when the list was cut. EarthScope data, reshaped from FDSN text to JSON and served by Eden Engine; not an official EarthScope product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "earthscopefdsnws/channels" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "earthscopefdsnws/channels" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "earthscopefdsnws/channels", input: { /* see input_schema */ }, dry_run: true })
