Providers
---------

Ethers works closely with an ever-growing list of third-party providers
to ensure getting started is quick and easy, by providing default keys
to each service.

These built-in keys mean you can use `ethers.getDefaultProvider()` and
start developing right away.

However, the API keys provided to ethers are also shared and are
intentionally throttled to encourage developers to eventually get
their own keys, which unlock many other features, such as faster
responses, more capacity, analytics and other features like archival
data.

When you are ready to sign up and start using for your own keys, please
check out the [Provider API Keys](https://docs.ethers.org/v5/api-keys/) in
the documentation.
