source: All eight OpenAPI definitions in openapi/ were scanned for 429 responses and for RateLimit-*, X-RateLimit-*
  and Retry-After response headers. No public Diebold Nixdorf API documentation site is reachable to corroborate.
limit_count: 0
limits: []
response_headers: []
exhaustion_status: null
note: 'No rate limit is published and none is signalled in the contract: not one of the 159 operations declares
  a 429 response, and no RateLimit-*, X-RateLimit-* or Retry-After header appears in any of the eight specifications.
  The responseCode enum does carry RESUBMIT alongside OK and FAIL, but that is a business instruction from the core
  banking host ("send this again"), not a throttling signal, and it comes with no window and no backoff guidance.
  Because Vynamic Transaction Middleware is customer-deployed, any real throughput limit is a property of the financial
  institution''s own installation and sizing, which Diebold Nixdorf does not publish. limit_count: 0 is an honest
  zero.'
