API Keys

Learn how to authenticate your requests to Shadow.

All API requests to Shadow are authenticated via API keys. This includes Shadow RPC requests, as well as api.shadow.xyz endpoints. You can create a new API key by going to your project’s settings page: https://app.shadow.xyz/settings.

Add your API key to the request header to authorize your Shadow API requests. This header must be included in every request.

X-SHADOW-API-KEY: <YOUR-API-KEY>

For example, this is how you’d authenticate a call to your Shadow RPC:

curl https://rpc.shadow.xyz/ethereum/mainnet/v1/<FORK>/<VERSION> \
  -X POST \
  -H "Content-Type: application/json" \
  -H "X-SHADOW-API-KEY: <YOUR-API-KEY>" \
  --data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}'
