workflow hitting API rate limits - how to throttle requests

i have a workflow that loops through about 500 records in a table and calls an external API for each one. the API has a rate limit of 10 requests per second and my workflow is blasting through them too fast and getting 429 errors is there a way to add a delay between iterations? or batch them somehow? in n8n i used the wait node but i dont see an exact equivalent here the retry mechanism catches the 429s and retries but then it just hits the limit again lol. need actual throttling not just retry
