FreeCodeCamp API is blocked ... what now?

Hi guys I’m busy with the FreeCodeCamp Camper Leaderboard project, but my api requests has been blocked due to too many requests. What can I do to get it unblocked as I need it obviously to complete the project. Please help. Thanks

What message do you get back? Did it work at first, or were you directly blocked?

The following was the response. It worked at first, but I guess I was refreshing the page too often or something.
“pen.js:38 GET 429 (Too Many Requests)”
