Integrations

256 Blocks provides a standard JSON-RPC interface that works with any Ethereum-compatible library. This section covers integration guides for popular SDKs across different programming languages, as well as AI agent platforms.

Authentication

All integrations use the same authentication method. Include your Endpoint Key (found in the endpoint settings screen) in the X-API-Key header:

X-API-Key: your-endpoint-key

The RPC endpoint URL format is:

https://rpc.256blocks.com/{chain}

For example, to connect to Ethereum mainnet:

https://rpc.256blocks.com/ethereum
