API request limits

When authenticated using an API key you can make up to 10 requests per second, per user. All requests by the same user share the same quota, even when using different API keys.

Authentication method	Limit	Period	Per
OAuth 2.0	10	1 second	User
API key	10	1 second	User

Handling rate limits

Once you exceed a rate limit, Fabric API will respond with a 429 HTTP code.
