API for crypto exchanges — BrokerLauncherbit
As the cryptocurrency market grows, fast and accurate access to blockchain data and market data has become a competitive advantage for exchanges. The BrokerLauncherbit API provides this data layer for exchange developers and businesses so they can access live prices, transactions, blocks and wallet addresses without integrating each network separately.
This page explains the role of the exchange API in the product infrastructure, the types of data available, the Core Hub and Gateway, the developer experience and the integration path with the exchange backend.
What is an API for a crypto exchange?
An API is the communication layer between the exchange software and data services — programmatically delivering price, transaction, block and address flows to the exchange product.
Without separate connections to each blockchain network, an exchange API can supply the data needed for the market dashboard, wallet, reporting and the exchange's pricing engine. This layer helps exchange operators and developers build a faster, more reliable product — sized to the service plan capacity and project needs.
Market Data
Market data
Live prices, trading volumes, daily changes and time series for the exchange's dashboard and pricing engine.
Blockchain Data
Blockchain data
Transactions, blocks, wallet addresses and their history on major networks — for wallets, monitoring and reporting.
Developer Integration
Developer integration
Documentation, code samples, API Key authentication, REST and WebSocket — a faster path to build product on top of the data layer.
Global blockchain access
A single API layer to connect to multiple blockchain networks and data services — stable, unified access, sized to the infrastructure and service plan.
Major networks
Connection to the main blockchain networks such as Bitcoin, Ethereum and other available chains — sized to the plan and project scope.
Real-time data
Live prices and network events via REST and WebSocket — for the market dashboard and the exchange's decision engine.
Historical data
History of transactions, prices and address events for analytics, reporting, audits and time series.
Easier integration
Instead of integrating each network separately, a single standardized API layer — saving development time and cost.
Real-time data delivery
A four-step path from the blockchain source to the exchange dashboard — designed for stability, scalability and reduced latency, sized to the service plan.
- 01
Blockchain Nodes
Distributed nodes of the major networks — the primary source of transactions, blocks and addresses.
- 02
Core Hub
Aggregation, normalization, caching and data preparation for delivery to consumers.
- 03
API Layer
Gateway, Auth, Rate Limit and REST/WebSocket channels for handling requests.
- 04
Exchange Platform
Exchange backend, wallet, dashboard and financial services connected to the API.
Easy access to blockchain data
Eight core data groups made available to the exchange and developers through the API.
Transactions
Details of executed transactions including sender, receiver, amount, fee, status and timestamp.
Blocks
Per-block chain data — creation time, transaction count, block hash and parent hash.
Wallet addresses
Balance, transaction history, event count and address behavior for wallet monitoring.
Transaction history
Time series of transactions for an address or a symbol, filterable by date range.
Live prices
Tick, Ask/Bid and mid price for supported currency pairs and tokens.
Trading volume
Market volume across different intervals, daily changes and time series for the market dashboard.
Market data
General market information, rankings, price changes and industry-wide indicators.
Historical data
Time series of price, volume and blockchain events — suitable for analytics, reporting and back-testing.
Developer-first design
Documentation, code samples, technical support and a clear integration path — so developers focus on building the product, not on working around integration.
API documentation
REST and WebSocket reference, endpoint descriptions, data models and error codes — delivered during onboarding and sized to the project scope.
Code samples
Snippets in popular languages (Node.js, Python, etc.) for calling the API and consuming WebSocket — accelerating development.
Technical support
Engineering team accompaniment during integration, troubleshooting, consumption tuning and usage pattern design — matched to the service plan.
Integration path
Transparent path from API Key issuance to Staging testing and rollout to Production, with the exchange backend's needs reviewed.
BrokerLauncherbit Core Hub — the data aggregation center
Six layers that compose the data flow from blockchain nodes to the exchange dashboard — designed for centralized, reliable data and optimal performance.
Layer 01
Blockchain Networks / Nodes
Primary sources — distributed nodes of major networks plus market sources.
Layer 02
BrokerLauncherbit Core Hub
Data aggregation hub — collecting from nodes, normalizing, caching and preparing for consumption.
Layer 03
Data Normalization
Unifying each network's data format into the standardized API model — ready for consumption by the client.
Layer 04
API Gateway
Authentication with API Key, Rate Limit, request routing and REST/WebSocket channels.
Layer 05
Exchange Backend
Exchange backend that consumes from the Gateway — Core, Wallet, Order Engine and financial services.
Layer 06
Wallet / Market / Dashboard / Analytics
Final consumption points — user wallet, market view, admin dashboard and reports.
Use cases for exchange operators
The most common API consumption scenarios in an exchange's infrastructure — from the market dashboard to reporting and monitoring.
Live price display
Price streaming for market pages and trading tools used by exchange users.
Transaction status checks
Confirmations, Pending/Confirmed status, network errors and user transaction tracking.
Wallet address monitoring
Balance, events and address behavior for internal wallets and reporting.
Transaction history
Retrieving trade/transfer history for the user dashboard and report files.
Market dashboard
Building a comprehensive market dashboard with price, changes, volume and time series.
Trading volume analysis
Market behavior analysis, volume pattern detection and periodic reports.
Wallet and financial service integration
Integrating internal wallets and the exchange's financial services with the data layer.
Reporting and monitoring
Exporting management reports, KPIs and monitoring service health.
API security, reliability and operations
The API's operational framework — authentication, consumption control, monitoring, logging and a design for stability and scalability sized to the service plan.
API Key authentication
Authentication with API Key/Secret, traffic encryption and access-level control per key.
Rate limit and consumption control
Request limits over a time window, quotas and burst policies — protecting service health.
Monitoring
Real-time monitoring of latency, errors, usage and backend health — with internal alerts.
Logging
Logging request and error events for audits, troubleshooting and compliance reports.
Error handling
Standard error codes, clear messages and recovery guidance for API clients.
Uptime and scalability
Designed for stability, monitoring and scalability — sized to the service plan capacity and agreed SLA.
