API Overview

The Blink API has two surfaces: transactions (write), signed RuntimeCalls submitted Borsh-encoded to the sequencer, and a normalized REST and WebSocket API (read and streaming) served by the indexer. All prices and sizes are integers (ticks, lots, atoms); see Data Structures & Constants.

Start here

• Get Started: the two surfaces, with quickstart examples.
• Signing Transactions: keys, wire format, replay protection.
• Data Structures & Constants: units and scalar types.

Transactions

Every transaction is submitted to the single Submit Transaction endpoint as a signed, Borsh-encoded RuntimeCall. The call is one of the four Blink modules' calls:

• Accounts: deposits, withdrawals, transfers, delegation.
• Spot: spot orders and market administration.
• Perps: margin, orders, leverage, vaults/BLP, protocol operations.
• Oracle: feeds and price updates.

See Signing Transactions for how to build and submit one.

Read (REST)

Served by the indexer; no authentication is required.

• Markets & Orderbook: metadata, depth, candles, stats
• Trades
• Accounts, Positions & Orders: balances, PnL, transfer history
• Funding & Liquidations
• Vaults & BLP
• Tokens: symbol and decimals registry
• System: status, info, config, exchange stats
• Explorer: transaction status and search

Streaming

• WebSocket: real-time orderbook, trades, and account updates.
