TON RPC Endpoint and API

The Open Network for everyone

TON applications should validate masterchain reads, account state, transaction lookups, and method calls before relying on an endpoint for production traffic.

Create a free API key for 400,000 response units per day and up to 40 response units/second. Method weights apply.

Public endpoint rate limit: 5 req/sec

Quick Start
curl -H 'Content-Type: application/json' -d '{"id":1,"jsonrpc":"2.0","method":"getMasterchainInfo"}' 'https://ton.api.onfinality.io/public'
curl -H 'Content-Type: application/json' -d '{"id":1,"jsonrpc":"2.0","method":"getMasterchainInfo"}' 'https://ton.api.onfinality.io/public'
HTTPs
https://ton.api.onfinality.io/public

GET CONNECTED

Connect to TON

Connect TON wallets and Telegram app backends to OnFinality RPC. Read masterchain data, inspect account state and track transactions for payment integrations.

Try the public interface

First request
curl 'https://ton.api.onfinality.io/public' \
  -H 'Content-Type: application/json' \
  --data '{"id":1,"jsonrpc":"2.0","method":"getMasterchainInfo"}'

Use the interface and request shown above for an initial check, then test the methods and traffic pattern your application actually needs.

BUILT FOR YOUR WORKLOAD

Build with TON

Plan access around the requests, operational requirements and release workflow your application needs.

Integration

Start with a connection check, then validate the reads, transactions or data workflows required by your application.

Usage planning

Review method-specific limits, plan allowances and usage before increasing traffic. Different methods can consume different response units.

Operations

Use your real client region and request pattern when evaluating latency, retries and service availability.

Never Worry about Infrastructure Again

OnFinality takes away the heavy lifting of DevOps so you can build smarter and faster.
