`json:$.price` or `jq:.price` would give `23.50`, or you can extract the whole structure
`json:$..price` or `jq:..price` would give `3949.99`, or you can extract the whole structure (use a JSONpath test website to validate with)
The application also supports notifying you that it can follow this information automatically
