Api Endpoint

Eckari

Identify which carrier issued a tracking number using a deterministic, versioned signature set - prefixes, lengths, carrier check digits and UPU S10 structure - returning the carrier, how distinctive the match is, every ranked candidate with typed evidence, and the parsed S10 details. No upstream call and no carrier account required. Use when: Which carrier is this tracking number from?
