BNSF · Rate Limits

Bnsf Rate Limits

BNSF publishes its API Gateway throttle limits verbatim inside the shared 429 response of every one of its eight OpenAPI documents. Every operation in the catalog (59 of 59) declares a 429 response carrying these limits. Limits are stated as flat gateway throttles, not as plan tiers — BNSF publishes no priced plans, so there is no per-tier variation to record.

Bnsf Rate Limits is the machine-readable rate-limit profile for BNSF on the APIs.io network, in the API Commons Rate Limits shape.

It captures 3 rate-limit definitions, measuring requests_per_second and requests_per_minute.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 429.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled and quotaExceeded.

Tagged areas include Freight, Railroad, Rate Limiting, and Throttling.

A shared ceiling. One partner's traffic can exhaust it for every other partner on the same service, which is a capacity fact a consumer cannot observe from its own quota.

Policies

Backoff on 429
BNSF's own wording: "Upon receiving such exceptions, you can resubmit failed requests in a rate-limited manner, complying with the API Gateway throttle limits." No Retry-After value is supplied, so the client chooses the interval.
504 recovery
On a 504 Gateway Timeout BNSF instructs callers to wait about one minute before retrying.
