Algorand (ALGO)

Algorand API reference for accessing Algorand nodes through GetBlock's Algod and Indexer REST APIs.

Algorand is a Layer 1 blockchain secured by Pure Proof-of-Stake, designed for instant, single-block finality with low, fixed fees. Proposed by Turing Award winner Silvio Micali and launched in 2019, it uses a verifiable random function committee to reach agreement, so blocks (called rounds) are final the moment they are committed — there are no reorganizations. Algorand has native tokenization through Algorand Standard Assets (ASAs) and stateful smart contracts (applications) that run TEAL on the Algorand Virtual Machine. Its native token is ALGO, denominated in microAlgos (10^-6 ALGO). GetBlock serves Algorand over two REST interfaces: algod (the node daemon) and the Indexer (archival search).

Key Features

• Pure Proof-of-Stake: A VRF-based committee reaches agreement with instant, single-round finality

• No Reorgs: Once a round is committed it is final, so confirmations are immediate

• Algorand Standard Assets: Native tokenization (fungible and non-fungible) without smart contracts

• AVM Smart Contracts: Stateful applications and stateless logic signatures written in TEAL

• Low, Fixed Fees: A minimum fee of 1,000 microAlgos per transaction under normal load

• Two REST APIs: algod for live node state and submission; the Indexer for historical search

TECHNICAL DISCLAIMER: AUTHORITATIVE REST API SPECIFICATION.

GetBlock's API reference documentation is provided exclusively for informational purposes and to optimize the developer experience. The canonical specifications for the algod and Indexer REST APIs are maintained and published by the Algorand Foundation and the go-algorand project at developer.algorand.org. Those OpenAPI specifications are the authoritative references.

Network Information

Property	Value
Network Name	Algorand Mainnet
Native Currency	ALGO (1 ALGO = 1,000,000 microAlgos)
Consensus	Pure Proof-of-Stake
Finality	Instant (single round)
Address Format	58-character base32
Block Time	~2.8 seconds
Node Software	go-algorand (algod) and Algorand Indexer

Interfaces

Interface	Transport	Use it for
algod (REST)	HTTP REST over the node daemon	Live node status, blocks, current account/asset/app state, suggested params, and transaction submission
Indexer (REST)	HTTP REST over the Indexer database	Archival, filtered search of transactions, accounts, assets, applications, and blocks

Use algod to read the current state and submit transactions, and the Indexer to search history with rich filters and pagination. Each is provisioned as its own endpoint in the GetBlock dashboard.

Interface Endpoints

algod (REST)

https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/

Indexer (REST)

https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/

Replace <ACCESS-TOKEN> with the token from the GetBlock dashboard. algod and the Indexer are separate endpoints — select the interface when you create the endpoint. Append the paths shown on each method page (for example v2/status or v2/transactions).
