PostNord vs UPS

PostNord's developer portal exposes REST APIs for shipment tracking, service-point lookup, pickup booking, and postal-code surcharge data across its Swedish and Danish delivery network. Every endpoint requires an x-bap-key API key issued through the portal's self-serve signup, and responses carry CORS headers for direct browser calls. A Free plan covers a meaningful daily quota per method — 500,000 tracking calls a day, for one — with a metered Customer plan billing per call once volume climbs past those limits.

UPS's REST APIs cover package tracking, rating, address validation, and label creation, authenticated via OAuth 2.0 client-credentials bearer tokens issued by the developer portal — the legacy Access Key scheme was retired for all UPS REST APIs in 2024. Calls carry no separate API fee: access is free for UPS account holders, who instead pay UPS directly for the shipments and services the calls represent.
