Instantly Ai Rate Limits

Instantly's published API rate limits. The global limits are workspace-wide — they are shared between API v1 and API v2 and across every API key in the workspace, so adding keys does not add headroom. A handful of endpoints carry their own, much lower limits. This file replaces the scaffold defaults written on 2026-05-22, which were invented placeholders (10/min free, 120/min pro) and did not match anything Instantly publishes.

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

It captures 7 rate-limit definitions, measuring requests_per_second, requests_per_minute, and requests_per_30_days.

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

The profile also includes response codes documented for throttled, quotaExceeded, and upstreamThrottled.

Tagged areas include Cold Email, Outbound, Sales, Deliverability, and Rate Limiting.
