Using your API key

Getting a key​

To get an API key:

  1. Sign in at https://voyager.online/
  2. Go to Services -> RPC
  3. Click the Create new + button
  4. Name your key
  5. Copy the key value

Requests​

You may pass your API key in a header or in the query string.

Some client SDKs situations only work with the query string approach. Everywhere else, it's preferable to use the header approach.

Pass an HTTP header called x-apikey. Do not prefix the value with Bearer, just pass the value of your API key.

curl --location 'https://rpc.nethermind.io/mainnet-juno/' \
--header 'x-apikey: API_KEY' \
--data '{
    "jsonrpc":"2.0",
    "method":"starknet_blockNumber",
    "id":1
}'

Query string​

Pass the value in a query string parameter called apikey, eg. /mainnet-juno/?apikey=API_KEY.

curl --location 'https://rpc.nethermind.io/mainnet-juno/?apikey=API_KEY' \
--data '{
    "jsonrpc":"2.0",
    "method":"starknet_blockNumber",
    "id":1
}'
