With a custom endpoint, you gain access to separate resources from the public www.bitgo.com API. This has the following advantages:
The public API endpoint is more susceptible to spam and attacks by malevolent individuals. With a custom endpoint and a different pool of resources, you will be less likely to be impacted by such attacks.
Your API calls are not processed on the same infrastructure as the public endpoint and do not go through Cloudflare, thus potentially increasing privacy for your requests.
BitGo reserves the right to rate limit requests to our public endpoint. On the
enterprise level custom endpoint, users are able to burst requests at a rate of 300 requests per minute or more.
Paying customers on the public endpoint receive an SLA target of 99.95% (more info at https://www.bitgo.com/sla). Custom endpoints receive an SLA target of 99.99%.
In a custom endpoint, your requests are not in the same queue as the public majority, resulting in improved performance.
