Authentication

Secure your API requests with API key authentication.

Your API key belongs to a NoLimitNodes project node.

    Sign in at app.nolimitnodes.com.

  2. Create or open a project

    Add a Solana node if the project has no node.

  3. Copy the node key

    Open the node page and copy its API key.

  4. Store the key

    Place the value in a secret manager or environment variable.
