api-key string

NOWNodes API key passed in the api-key header.

Retrieves a single Checkpoint by sequence number, digest, or latest from the iota.grpc.v1.ledger_service.LedgerService gRPC service. This is a server-streaming method: the checkpoint payload (summary, contents, transactions, and events) is chunked across CheckpointData messages, so the client may receive several messages for one checkpoint. The default read_mask is summary.
