Semrush Rate Limits
Published rate limits for the Semrush API surface, read from the provider's API usage restrictions page. Replaces the 2026-05-04 bulk-sweep scaffold, whose header names and tier numbers were invented defaults. The real posture: a flat 10 requests per second and 10 concurrent requests per account across every Semrush API, per-method exceptions on the Listing Management API, and — critically — no rate-limit response headers of any kind.
Semrush Rate Limits is the machine-readable rate-limit profile for Semrush on the APIs.io network, conforming to the API Commons Rate Limits specification.
It captures 13 rate-limit definitions, measuring requests_per_second, concurrent_requests, requests_per_month, and requests_per_minute.
The profile also includes response codes documented for throttled, quotaExceeded, serviceUnavailable, and serviceUnavailableLocal.
Tagged areas include Data, Search Engines, Rate Limiting, Quotas, and Throttling.
