ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

Returns the latest finalized or canonical block with full extrinsic and event details. An entry that could not be decoded is still returned at its own index, with decodeError set, no method or args, and era as an empty object, and the response carries partial: true; its events, success and paysFee come from the block's events, and success is false when the block carried no outcome event for that index. Events emitted after the last extrinsic, by the FRAME poll hook or a multi block migration, are returned in a separate afterExtrinsics object, omitted when the block has none.
