429 Rate limit reached '/testscript'

For the past two days, we have been receiving 429 errors when requesting the BDD body of a test case.

{'code': '429', 'error': 'Rate limit reached. Please try again after 5 minutes.'}

Could you please clarify the situation? Have any new rate limits been introduced? Is this behavior described in the documentation?
