Astronomical Object Name to Coordinates (MAST)

mast/name-lookup

Resolves an astronomical object name (for example M31, NGC 1275, Vega, TRAPPIST-1) to its sky position through the MAST name resolver (SIMBAD or NED): the canonical name, the resolver used, right ascension and declination in degrees (ICRS) and the object type. A name that nothing resolves returns count 0. Use the result with the observations tool. Source: Mikulski Archive for Space Telescopes (MAST), STScI.

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

// 2. inspect: price and input schema
omnial_inspect({ tool: "mast/name-lookup" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "mast/name-lookup" })

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

// 5. settle: the call is charged when it finishes, nothing to do
