This is an honest zero, and for this provider it is also a defensible one: Karrio is deployed per instance — self-hosted or managed — so throughput is a property of the operator's own deployment, not of a shared multi-tenant gateway. What is missing regardless of deployment model is the runtime signal: the contract declares no 429 response and no rate-limit response header on any of its 95 operations, so a client has no in-band way to learn it is being throttled by whatever sits in front of an instance. limit_count: 0 headers: limit: null remaining: null reset: null retryAfter: null policy: null published: false responseCodes: throttled: null note: >- No 429 response is declared on any operation in the OpenAPI. The declared error codes are 400, 401, 404, 409, 424 and 500. limits: [] evidence: - check: X-RateLimit-* / RateLimit-* / Retry-After headers in the OpenAPI result: zero occurrences across 496 KB of contract - check: 429 response declared on any of 95 operations result: none - check: rate limits or quotas on the pricing FAQ at https://karrio.io/platform result: 'HTTP 200; no limit stated for any of the three tiers' - check: https://karrio.io/pricing result: HTTP 404 downstream_note: >- The binding constraint on a Karrio integration is usually not Karrio but the carrier behind it. Carrier rate limits surface as HTTP 424 with the carrier's own message and carrier_name attribution — see errors/karrio-problem-types.yml. An agent should treat 424 rather than 429 as the throttling signal on this API. maintainers: - FN: Kin Lane email: kin@apievangelist.com
