Tracking — entry 009 of 9
WhereParcel
WhereParcel is a unified parcel-tracking API that normalizes shipment status across 64+ carriers — including USPS, UPS, FedEx, DHL, and TNT — behind a single REST endpoint and webhook system, so integrators don't need a separate connector per carrier. Every request is authenticated with a Bearer API key and answered with full CORS support for browser-side calls, typically in 500ms for cached lookups and 2-3 seconds for live carrier queries. There's no free-forever tier: plans start at $49/month for 10,000 requests, each with a 7-day free trial.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
