Analytics API 429 on High-Frequency GET /api/v2/analytics/queues/summary

Can’t quite understand why the /api/v2/analytics/queues/summary endpoint returns 429 Too Many Requests during our JMeter burst tests from Singapore.

“Rate limits are applied per tenant and per scope. Exceeding these limits will result in a 429 response.”

Our script hits 50 concurrent requests per second. The docs do not specify the exact threshold for this scope. Is there a way to increase the limit for load testing?
