Resources
Sonic Public RPC Endpoint
Connect to OnFinality's Sonic public RPC endpoint for fast and reliable blockchain access. Built for developers who need stable performance across testing, deployment, and live application usage.
The below example uses the public API endpoint*. This endpoint is only suitable for testing. To avoid rate limiting and service interruption, sign up now to get your own API key.
curl -H 'content-type:application/json' -d '{"id": 1, "jsonrpc": "2.0", "method": "eth_blockNumber"}' 'https://sonic.api.onfinality.io/public'https://sonic.api.onfinality.io/publicwss://sonic.api.onfinality.io/public-ws* The public endpoint is rate limited

Why Choose OnFinality for Sonic Infrastructure?
Reliable blockchain infrastructure matters when your product depends on speed, uptime, and accurate onchain data.
High Performance Access
Support demanding Sonic workloads with infrastructure designed for reliable throughput and stable performance.
Powerful RPC Analytics
Monitor RPC usage and performance with analytics that help teams manage and scale blockchain infrastructure more effectively.
99.99% Uptime
Run production applications on Sonic with dependable infrastructure built for availability and consistency.
Connect via HTTPS or WebSocket
Use flexible connection options for applications that need both standard requests and real-time blockchain updates.
Decentralized Servers Hosted Globally
Access globally distributed infrastructure that improves resilience, reliability, and service reach.
Full Archive Access at No Extra Cost
Access historical Sonic blockchain data for deeper querying, analytics, and advanced application needs.
Build faster with Sonic RPC endpoints
Use OnFinality's Sonic RPC APIs to connect wallets, dApps, dashboards, bots, and backend services without operating your own node from day one.
Public endpoint testing
Start with the Sonic public RPC endpoint for lightweight checks, prototypes, and quick integration tests.
Authenticated API access
Move production traffic to authenticated endpoints when you need clearer limits, analytics, and operational visibility.
Standard RPC methods
Query Sonic blocks, transactions, balances, events, and chain state through familiar HTTP and WebSocket workflows.
Operate Sonic infrastructure with more control
Production teams need more than an endpoint URL. They need observability, predictable capacity, and a path from shared RPC access to isolated infrastructure.
Request visibility
Track usage patterns and response activity so your team can understand traffic growth before it becomes an incident.
Dedicated node path
Use dedicated Sonic nodes when your workload needs isolated resources, custom operations, or stronger capacity planning.
Archive and historical data
Plan for archive access when analytics, audits, indexers, or advanced app features need older Sonic state.
Choose the right Sonic RPC setup
Different Sonic products need different infrastructure. OnFinality gives teams a practical path from public RPC testing to production-grade API and node operations.
For prototypes
Use public RPC for simple reads, connection checks, and early experiments where strict performance guarantees are not required.
For live apps
Use authenticated API endpoints when users depend on stable request handling, monitoring, and scalable access.
For heavy workloads
Use dedicated nodes for sustained traffic, latency-sensitive services, validator tooling, exchange systems, and indexing pipelines.
Never Worry about Infrastructure Again
OnFinality takes away the heavy lifting of DevOps so you can build smarter and faster.
