Getting Started
Getting Started with the Data API
To begin, create your free account by visiting Builder Hub Console.

Once the account is created:
- Navigating to Data API Keys
- Click on Create API Key
- Set an alias and click on create
- Copy the the value

Always keep your API keys in a secure environment. Never expose them in public repositories, such as GitHub, or share them with unauthorized individuals. Compromised API keys can lead to unauthorized access and potential misuse of your account.
With your API Key you can start making queries, for example to get the latest block on the C-chain(43114):
curl --location 'https://data-api.avax.network/v1/chains/43114/blocks' \
--header 'accept: application/json' \
--header 'x-glacier-api-key: <YOUR-API-KEY>' \And you should see something like this:
