BNSF
BNSF Railway, a subsidiary of Berkshire Hathaway Inc., operates one of the largest freight rail networks in North America — more than 32,000 route miles across 28 states and three Canadian provinces, connecting to Mexico through rail lines in Texas. BNSF publishes a genuine customer-facing API programme: eight OpenAPI 3.0 documents totalling 59 operations covering shipment tracing, intermodal and automotive hub gate operations, freight pricing and invoices, intermodal schedules, waybill management, rail reference data and diagnostics, plus a six-event webhook push surface. Every call is authenticated with certificate-based mutual TLS on port 6443; there is no API key and no OAuth, and 27 of the 59 operations are Restricted Services requiring separate authorisation.
BNSF publishes 5 APIs on the APIs.io network, including AUTOMOTIVE API, CARLOAD API, INTERMODAL API, and 2 more. Tagged areas include Freight, Railroad, Shipping, Trains, and Intermodal.
The BNSF catalog on APIs.io includes 1 event-driven AsyncAPI specification.
BNSF’s developer surface includes authentication, sandbox, developer portal, documentation, API reference, developer console, getting-started guide, and 33 more developer resources.
