# walk a big JSON file and match schemas as they are read
price-validator --walk-and-match ../data-files/in-network-rates-fee-for-service-sample.json --schema ../schemas/negotiated-rate.json

# walk a big JSON file, match schemas, and write to an output file in NDJSON format as they are read
price-validator --walk-and-match ../data-files/in-network-rates-fee-for-service-sample.json --schema ../schemas/negotiated-rate.json --save ../output/network-rates.ndjson
