REST tools

note

We are currently updating this documentation. While it offers a general overview, some details may be outdated. Please check back soon for the latest version.

Using the REST web tools, users can perform HTTP-based interactions with the blockchain to access vital information. This includes querying transaction records, inspecting block data, reviewing the blockchain’s current state, fetching configuration settings, and other related details.

Postchain API usage

The Postchain REST tool doesn't require installation, as it can be used directly in a web browser to send requests and receive responses.

The REST tool offers the following groups of APIs, each containing a set of underlying methods available for use:

Block	Blockchain	Configuration	Error	Experimental	Node	Query	Transaction
Fetch blocks info	Fetch height of next block to be built/synced	Fetch blockchain configuration	Fetch blockchain errors	Fetch current state of blockchain node	Query node EBFT status	Make query	Submit transaction
Fetch block info by block RID	Get API version for the subnode	Validate blockchain configuration			Query all nodes EBFT statuses	Make web query	Fetch list of waiting transaction RIDs
Fetch block info by block height		Fetch the next blockchain configuration height			Get blockchain RID	Make a query with GTV encoded response	Fetch waiting transaction
Confirm block by block RID		Fetch the blockchain configuration features			Get API version	Make a GTV encoded query	Fetch list of rejected transactions
					Get infrastructure version		Fetch transaction
					Get infrastructure version for the subnode		Fetch transaction info
					Check anchoring status for a blockchain		Fetch transactions info
							Fetch number of successful transactions
							Fetch transaction confirmation proof
							Fetch transaction status
