Package Tracking APIs
Package tracking APIs are either multi-carrier aggregators or a single postal service. AfterShip detects the courier and returns tracking status and delivery estimates across hundreds of carriers. WhereParcel, a paid API, puts global carriers behind one REST endpoint with webhooks. Correios covers Brazil only, adding CEP postal-code lookups and shipping price quotes to its tracking.
