Expand description

The API offered by the Diem Data Client.

Required methods

Returns a global summary of the data currently available in the network.

This API is intended to be relatively cheap to call, usually returning a cached view of this data client’s available data.

Returns a single account states chunk with proof, containing the accounts from start to end index (inclusive) at the specified version. The proof version is the same as the specified version.

Returns all epoch ending ledger infos between start and end (inclusive). If the data cannot be fetched (e.g., the number of epochs is too large), an error is returned.

Returns the number of account states at the specified version.

Returns a transaction output list with proof object, with transaction outputs from start to end versions (inclusive). The proof is relative to the specified proof_version. If the data cannot be fetched (e.g., the number of transaction outputs is too large), an error is returned.

Returns a transaction list with proof object, with transactions from start to end versions (inclusive). The proof is relative to the specified proof_version. If include_events is true, events are included in the proof. If the data cannot be fetched (e.g., the number of transactions is too large), an error is returned.
