This document lists the quotas and system limits that apply to
Blockchain RPC.
Quotasspecify the amount of a countable, shared resource that you
can use. Quotas are defined by Google Cloud services such as
Blockchain RPC.
System limitsare fixed values that cannot be changed.
Google Cloud uses quotas to help ensure fairness and reduce
spikes in resource use and availability. A quota restricts how much of a
Google Cloud resource your Google Cloud project can use. Quotas
apply to a range of resource types, including hardware, software, and network
components. For example, quotas can restrict the number of API calls to a
service, the number of load balancers used concurrently by your project, or the
number of projects that you can create. Quotas protect the community of
Google Cloud users by preventing the overloading of services. Quotas also
help you to manage your own Google Cloud resources.
The Cloud Quotas system does the following:
Monitors your consumption of Google Cloud products and services
In most cases, when you attempt to consume more of a resource than its quota
allows, the system blocks access to the resource, and the task that
you're trying to perform fails.
Quotas generally apply at the Google Cloud project
level. Your use of a resource in one project doesn't affect
your available quota in another project. Within a Google Cloud project, quotas
are shared across all applications and IP addresses.

System limits can't be changed.
Rate quotas
The following quotas apply to Blockchain RPC requests:
Quota
Value
Max requests per minute per project
6,000
Max requests per day per project
1,000,000
For details on each RPC method and how they contribute to the quota, viewRPC API.
Request a quota increase
To adjust most quotas, use the Google Cloud console.
For more information, seeRequest a quota adjustment.
System Limits
Unlike quotas, system limits cannot be changed. The following limits apply to
Blockchain RPC requests:
