Total API Requests
Total API requests are limited in accordance with your current Apollo plan. Review Apollo’s API pricing to determine how many requests you can make per month.
The headers of successful API responses show both how many requests you’ve used and how many requests your Apollo plan provides. Apollo uses a fixed-window rate limiting strategy for API calls. As an example of this strategy, if your team’s rate limit is 50 requests per minute, those requests can be made at any interval within a 60-second window.
