SONARX API
Programmatic Access to Datashares & Historical Balances
Access SonarX datashares and query historical wallet balances across supported chains via clean REST endpoints.
Core Capabilities
DATASHARE ACCESS
Query SonarX datashares via REST endpoints. The same data available through Snowflake, BigQuery, and Databricks — no data warehouse required.
- 130+ chains from genesis to near real-time
- Blocks, transactions, transfers, logs, traces, receipts
- No data warehouse setup required
HISTORICAL BALANCES
Query wallet balances at any point in time with block-level precision across supported chains.
- 21 EVM chains with point-in-time by block number
- Solana with historical and real-time endpoints
- SOL balances, SPL token balances, and token metadata
Historical Balance Coverage
Chains currently supporting point-in-time balance queries via the API.
EVM CHAINS
SOLANA
Historical and real-time SOL and SPL token balance queries.
Historical balance support is continuously expanding. Request a chain if you need coverage for a specific network.
Technical Specifications
AUTHENTICATION
API key authentication via the apikey header. Get started in minutes.
LATENCY
Ultra-low latency response times. Real-time endpoints deliver data seconds from tip.
COVERAGE
Datashare access across 130+ chains. Historical balance endpoints for 21 EVM chains and Solana.
Use Cases
PORTFOLIO TRACKING
Portfolio dashboards with real-time and historical balance queries across chains.
COMPLIANCE & AUDITS
Point-in-time balances at any block for reconciliation and regulatory compliance.
DEFI ANALYTICS
Analyze protocol interactions, liquidity flows, and yield using balance and transfer data.
TRADING INFRASTRUCTURE
Low-latency balance and transaction data for trading algorithms and execution.
WALLET RECONCILIATION
Verify wallet holdings at specific blocks across chains for accounting and reporting.
CROSS-CHAIN APPLICATIONS
Unified API interface for multi-chain applications across EVM and Solana.
Benefits
HISTORICAL POINT-IN-TIME BALANCES
Query any wallet balance at any point in time across supported chains for audits, compliance, and reconciliation.
