Observe: you will need to have curl and jq installed.
Orientate: get to BLS Data finder page
Decide: pick a series
Act: pipe curl into jq and play around with jq filter strings

Example: Testing the pipes

Lets say we want the series named :All items in U.S. city average, 
all urban consumers, not seasonally adjusted.  We need the 
series ID: CUUR0000SA0

curl https://api.bls.gov/publicAPI/v2/timeseries/data/CUUR0000SA0 \
 | jq .

Example: Grabing JSON for later (bcz of bls.gov data limits)
---
curl https://api.bls.gov/publicAPI/v2/timeseries/data/CUUR0000SA0 > \
CUUR000000SAO.json


Example: using JSON file just like a curl stream 
---
cat CUUR000000SAO.json | jq .

Example: Filter data for x/y graph 
---
cat CUUR0000SA0.json | jq '.Results.series[].data[] | {year, period, value}'
