TON HTTP API C++

The HTTP API C++ for The Open Network is a real-time API to connect to TON blockchain lite servers via ADNL protocol and enable access to lite servers through HTTP requests.

This service is the improved version of original TON HTTP API, written entirely in C++ to achieve outstanding performance and effecient comnsuming of hardware resources.

Features

TON HTTP API C++ provides following features:

• Load balances requests to TON nodes
• Checks availability of Lite Servers, disables unavailable and out-of-synced nodes.
• Additionally parses data returned by original TONLib.
• Based on userver, service provides detailed and Prometheus-compatible usage statistics.

Key differences from toncenter/ton-http-api

• C++ version consumes significantly less CPU and memory resources.
• C++ version uses single instance of TONlib for each Lite server, meanwhile Python version TONLib instances number for each Lite server was equal to number of Gunicorn workers. This significantly decreases the number of healthcheck requests to Lite servers.
• Cache now is integrated in service, no separate Redis is required to enable caching feature.

Hardware Requirements

• OS: Linux or MacOS (Windows is not supported).
• CPU: 2 vCPU, x86_64 or arm64 architecture.
• RAM: minimum 2GB, 8GB recommended for caching.

Deploy

There are two main ways to run TON HTTP API:

• Docker Compose: flexible configuration, recommended for production environments, works on any x86_64 and arm64 OS with Docker available.
• Local (experimental): only for development purposes.

Docker Compose

• (First time) Install required tools: docker, docker-compose, curl.
  • For Ubuntu: run scripts/setup.sh from the root of the repo.
  • For MacOS and Windows: install Docker Desktop.
  • Note: we recommend to use Docker Compose V2.
• Download TON configuration files to private folder:

  mkdir private
  curl -sL https://ton-blockchain.github.io/global.config.json > private/mainnet.json
  curl -sL https://ton-blockchain.github.io/testnet-global.config.json > private/testnet.json

• Copy service configuration file and adjust params:

  cp config/config_vars.yaml private/config_vars.yaml
  nano private/config_vars.yaml

  • To run testnet version or connect to your private TON node, please specify:

  export THACPP_GLOBAL_CONFIG_PATH=private/testnet.json
  # or
  echo "THACPP_GLOBAL_CONFIG_PATH=private/testnet.json" > .env
  

• Pull or build docker image:

  docker compose pull
  # or 
  docker compose build

• Run service:

  docker compose up -d
  # or
  docker compose up

• Additionally check service logs:

  docker compose logs http-api-cpp
  # or 
  docker compose logs -n 100 http-api-cpp
  # or 
  docker compose logs -f -n 100 http-api-cpp
