Is there a rate limit for the Vexcel API?

Yes, 500 Queries per second (QPS) per IP Address is the ceiling for the API for all services.

A 429 error indicates that the request rate has exceeded the allowed threshold and your traffic is being throttled. To resolve this, we recommend using an "exponential backoff" approach. This approach involves progressively increasing the wait time between retries (e.g., 1 second, then 2 seconds, 4 seconds, 8 seconds, up to a maximum delay). This reduces the chance of hitting the limit repeatedly and allows the server load to stabilize
