Get API Keys

To call Onbeam from the docs playground or your backend, you need an API key.

Create a key

Sign in to your Onbeam dashboard
Go to API settings
Create a new API key
Copy it and store it securely

Use it in requests

Send your key in the x-api-key header:

curl https://api.onbeam.io/wallet/smart-account \
  -H "x-api-key: $ONBEAM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"ownerAddress":"0x1234567890abcdef1234567890abcdef12345678","chainId":80002}'

In the docs, open any endpoint page and paste your key into the auth field in Try It.
