# R+L Carriers Fuel Surcharge API

R+L Carriers (SCAC: **RLCA**) publishes a weekly fuel surcharge table with the DOE #2 diesel price that triggered each rate. The upstream tariff page consistently exposes the past 52 weeks. NexusFeed parses the page in headless Chromium and returns rates newest-first.
