api.tradeenergy-api.workers.dev/api/logistics/hazardous-placard-id
Placard / label codes for a hazardous material from the US DOT table (49 CFR 172.101, eCFR), by UN number (e.g. 1203) or name fragment: label codes, hazard class and packing group. Returns the label code numbers as written in the table; it does not give the placard artwork or emergency response guide entries. Usually answers in a few seconds, up to 16 s on slower calls; allow a 30 s timeout.
