Make a query

With your API Key you can start making queries, for example to get the latest block on the C-chain(43114):
  curl --location 'https://glacier-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:
