# Overview

Access TON data via public liteservers, hosted APIs (TON Center v2/v3, TonAPI, dTON), or self-hosted options.

<sup>1</sup> TonAPI's full indexer is not open-source; [OpenTonAPI][eta-oss-src] is a limited open-source version.

<sup>2</sup> **Indexer** means the service maintains its own database derived from blockchain data for richer queries (traces, jettons, NFTs, etc.), beyond raw liteserver RPC.

<sup>3</sup> **Archival** indicates historical data retention. For liteservers, this depends on the node's archival configuration; hosted indexers typically keep full history, but exact retention policies are service-specific.

<sup>4</sup> **Proofs** denote responses that can be verified without trust using cryptographic proofs from the network (liteserver/tonlib-based). HTTP indexers typically do not return proof bundles in their REST/GraphQL responses.
