Unified, multichain blockchain data API

Query any chain
through one API

Unified API lets you access NFT, token and transaction data across many blockchains with a single, normalized schema.
Fewer RPC calls, less boilerplate, and faster time to production for every Web3 product.

Start with Unified API

Unified API

A superior way to query blockchains. Access normalized NFT, token, block and transaction data across multiple networks through a single, developer-friendly API.
Built to replace custom indexers and reduce raw RPC complexity in production apps.

NFT API

Search NFTs and holders, fetch metadata and transfers, and work with ENS, POAP and Unstoppable Domains across many mainnets and testnets — all via one unified NFT API.

Token API

Get token balances, prices, holders and transfers using indexed on-chain data. Perfect for wallets, exchanges, portfolio trackers and DeFi dashboards that need fast, accurate token information.

Query API

Retrieve blocks, block ranges, transactions, internal calls, events and logs with near-instant response times. Query multiple chains in one request and power analytics, monitoring and custom indexers.

SDK & Tooling

Use ready-to-go SDKs and examples to integrate Unified API into your backend, data pipelines and dashboards. Ship faster without reinventing blockchain data access.

Supported Networks

Unified API works across 19+ mainnets and 6+ testnets, so you can query on-chain data from a single endpoint.
From Ethereum and BNB Chain to Solana, Tron, TON, Bitcoin and more — one schema, many blockchains.

Solana SOL

High-speed blockchain for scalable DeFi and ultra-low-fee Web3 apps.

Ethereum ETH

The leading smart-contract blockchain powering DeFi and NFTs.

Tron Tron

Fast blockchain for global payments, DeFi, and stablecoin transfers.

Bitcoin BTC

The original decentralized blockchain for secure peer-to-peer payments.

TON TON

Telegram-native blockchain built for mass adoption and lightning speed.

BNB Smart Chain BNB

Low-fee EVM blockchain for smart contracts and a thriving DeFi ecosystem.

View all protocols Get your API key

Built for every on-chain data use case

Wallets, NFTs, trading, analytics and compliance — Unified API gives you a single, normalized way to read blockchain data across chains.

Wallets

Show multi-chain balances, history and token portfolios with one API instead of custom indexers per network.

NFTs & collections

Power NFT marketplaces, galleries and analytics tools with metadata, holders and transfer history from many chains.

Payments & settlement

Verify on-chain payments, reconcile incoming transfers and track settlement flows using indexed transaction data.

Trading & DeFi

Build trading tools, portfolio trackers and DeFi dashboards with fast access to token transfers, pools and protocol activity.

Analytics & BI

Feed ClickHouse, BigQuery and data warehouses with normalized, analytics-ready blockchain datasets across chains.

Risk & compliance

Enrich AML, wallet screening and transaction monitoring with detailed on-chain histories and entity-level insights.

learn more about Unified API

Unified API is a multichain blockchain data layer that lets you query NFTs, tokens, blocks, transactions, events and logs across many networks using a single, normalized schema.

RPC Gateway exposes native JSON-RPC methods for each chain. Unified API returns higher-level, indexed data structures (NFTs, tokens, blocks, logs) in one format across networks, reducing the need to build and maintain your own indexers.

Unified API covers 19+ mainnets and 6+ testnets, including popular EVM chains and non-EVM networks. New blockchains are added based on demand and enterprise requests.

You can search for NFTs, collections and holders, fetch metadata, transfers and activity across chains. It’s ideal for NFT marketplaces, explorers, galleries and analytics dashboards.

Yes. Unified API returns structured JSON that integrates well with data warehouses like ClickHouse or BigQuery and with Python-based machine learning stacks for on-chain analytics and scoring.

We provide code examples and SDKs for popular languages so you can integrate Unified API into your backend, cron jobs and data pipelines with minimal setup.

Unified API uses transparent, usage-based pricing. You start with a free tier for development and pay only when your project scales and requires higher request volumes or enterprise features.

Yes. One of the core benefits of Unified API is multi-chain search: you can request data from several networks in one query and receive normalized responses in a single payload.

Unified API is optimized for fast interaction with archive data, letting you query large block ranges, past transactions and historical token or NFT states.

Yes. Unified API provides structured historical data, EventStream delivers real-time events, and AML Intelligence adds risk and compliance signals. Together they form a complete Web3 data stack.

Most teams integrate in a few hours: request an API key, pick the endpoints for your use case (NFT, Query, Token) and plug our examples into your existing backend or data layer.

Enterprise customers can get custom SLAs, dedicated infrastructure and private endpoints tailored to high-volume analytics, exchanges, or large-scale dApps.
