Kling AI · Rate Limits

Kling Ai Rate Limits

Kling AI's generative work is asynchronous, so throughput is governed less by a per-minute request cap and more by how many generation tasks an account may run concurrently. Concurrency allowances scale with account tier and prepaid spend; higher tiers and enterprise agreements raise the number of simultaneous in-flight video/image tasks. The lightweight create and query (polling) calls are subject to request-rate limiting; exceeding it returns HTTP 429. Kling does not publish a single authoritative numeric table, so the figures here are indicative and NOT reconciled.

Kling Ai Rate Limits is the machine-readable rate-limit profile for Kling AI on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring tasks, requests, and seconds.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Video Generation, AI Video, Generative AI, Rate Limiting, and Concurrency.

Policies

Async Task Model
Submit a task, receive a task_id, then poll the matching query endpoint until status is succeed or failed. Assets return as URLs that expire and should be downloaded promptly.
Callback Notifications
A callback_url may be supplied on task creation to be notified on completion instead of tight polling.
Backoff Strategy
Poll on an interval with exponential backoff and jitter; honor 429 responses and any Retry-After header.
