+## Types of API
+
+TON exposes several access layers for interacting with the blockchain, each serving different needs:
+
+- **HTTP API** - standard web access for querying accounts, blocks, and sending transactions.
+- **Indexed API** - database-backed API providing structured, decoded, and historical data.
+- **ADNL** - low-level peer-to-peer protocol for direct communication with nodes.
+
+
+
+## HTTP API
+
+The HTTP API exposes the TON blockchain through both **REST** and **JSON-RPC** interfaces.\
+It allows developers to fetch account and wallet information, explore blocks and transactions, send messages, call smart contract methods, and more.
+
+
+
+### Typical use cases
+
+- Querying accounts, balances, or transactions
+- Sending messages or deploying smart contracts
+- Building wallets and basic dApps
+
+### Run your own instance
+
+Use the open-source [ton-http-api](https://github.com/toncenter/ton-http-api) to host your own endpoint.
+
+## Indexed API
+
+Indexed APIs extend HTTP functionality by offering structured, decoded, and historical blockchain data.\
+They are built on top of the **TON Indexer**, which reads data from a full node, decodes transactions and actions, and stores them in a PostgreSQL database for efficient querying.
+
+These APIs power explorers and analytics tools that need complex searches or decoded data.
+
+### Typical use cases
+
+- Blockchain explorers and analytics dashboards
+- Historical or decoded transaction queries
+- NFT and Jetton tracking
+
+### HTTP vs Indexer
+
+| Type | Best for | What you get |
+| ----------- | ----------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **HTTP** | Sending messages or performing standard read requests | Data processed by `tonlib` and served through liteservers over REST or JSON-RPC. Useful for querying accounts, balances, or transactions without indexing overhead. |
+| **Indexer** | Accessing decoded, historical, or aggregated data | Responses served from an indexing database built from a full node’s data. Ideal for explorers, analytics, and structured blockchain queries. |
+
+
+
+### Run your own instance
+
+Use the open-source [ton-indexer](https://github.com/toncenter/ton-indexer) to host your own endpoint.
+
+## ADNL API
+
+**ADNL (Abstract Datagram Network Layer)** is TON’s peer-to-peer protocol for direct node communication.\
+It provides verifiable, low-level access to blockchain data and transaction submission.
+
+Clients connect directly to **liteservers** using a binary protocol, downloading key blocks, account states, and Merkle proofs to verify data authenticity.
+
+For read operations (such as `runGetMethod`), the client executes a local TVM run using the verified state, without downloading the full blockchain.
+
+### Typical use cases
+
+- Running validators or custom node software
+- Building node management and monitoring tools
+- Applications requiring Merkle-proof validation
+
+### HTTP vs ADNL
+
+| Type | Best for | What you get |
+| -------- | ---------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **HTTP** | General-purpose access to blockchain data and message submission | Returns processed data produced by `tonlib` through liteservers, exposed over REST or JSON-RPC. The data is already parsed and formatted for applications, not a raw or verifiable ledger snapshot. |
+| **ADNL** | Direct and verifiable access to the blockchain state | Native peer-to-peer protocol used by TON nodes. Provides binary responses with Merkle proofs, allowing clients to verify the authenticity of account states and transactions directly. |
+
+
+
+### Run your own instance
+
+Use [MyTonCtrl](../node/setup-mytonctrl) to enable a liteserver and expose an ADNL endpoint.
