How do I get the metadata for a BigQuery query through the HTTP api -

i'm working on type provider f# , implement need schema query compile time, means has fast. of moment run this:

bq query --format=json --dry_run=true --use_legacy_sql=false 'select @a true x, @b + 1 y, "foo" = @c z, ["tomas", "jansson"] w, struct("wat" t, 69 u) v, [struct(3, "allo" g), struct(5 a, "yolo")] u, struct(["a"] h) t;' 

which want, uses bq tool. want know underlying http call have trouble finding in code base.

the reason want know underlying code base because want remove of third party dependencies possible might not available on build server or take long time setting up.

or can use

jobs: insert query configuration property , dryrun set true
