Bot API 429 during JMeter load test

Trying to make sense of why the Bot API returns 429 Too Many Requests immediately. Running JMeter 5.6.2 from Singapore. Targeting bot operations. Simulating 100 concurrent requests. Hitting rate limits instantly. What is the correct way to handle rate limits for bot operations?

Is there a specific limit for bot endpoints?
