Blockchain Data APIs & Indexing Infrastructure

Moralis provides comprehensive blockchain data indexing infrastructure that transforms raw on-chain data into structured, queryable formats for application developers across 50+ blockchains. The platform offers unified REST/GraphQL API endpoints for indexed wallet data, token information, NFT metadata, DeFi protocol data, and raw blockchain transactions.

Core Data APIs

Wallet API

Access complete wallet data including balances, transaction histories, NFT holdings, token portfolios, and real-time wallet activity. All data is decoded and enriched with human-readable labels, normalized across multiple chains for consistent querying.

Token API

Query token balances, transfers, metadata, holder information, and liquidity data across all major blockchains. Access token swap data from decentralized exchanges, track token adoption, and analyze market health with detailed holder analytics.

NFT API

Retrieve comprehensive NFT data including ownership, metadata, collections, transfer history, and marketplace activity. The API handles metadata resolution from both on-chain and IPFS sources, supporting ERC-721 and ERC-1155 standards across 40+ chains.

DeFi API

Access decentralized finance protocol data including liquidity pools, trading positions, yields, and protocol metrics. Get real-time pool reserves, user positions, TVL data, APY calculations, and DEX trading information across major protocols.

Blockchain API

Query raw blockchain data including blocks, transactions, internal transactions, and logs with full decoding. Essential for blockchain explorers, compliance tools, and applications requiring low-level blockchain data access.

Real-Time Event Streaming

Moralis Streams provides real-time blockchain event monitoring with guaranteed delivery. Track wallet addresses and smart contract events across multiple chains simultaneously with sub-second latency. Monitor millions of addresses with automatic retry mechanisms and 100% delivery guarantees - over 2.5 billion events and 227+ million webhooks delivered. Receive decoded, human-readable JSON webhooks with enriched metadata and sophisticated filtering rules.

Enterprise Data Exports

Moralis Datashare exports massive pre-indexed blockchain datasets directly to enterprise data warehouses (BigQuery, Snowflake, Amazon S3, Databricks). Access complete historical blockchain data across 30+ chains in JSON, Parquet, or CSV formats. Receive decoded, normalized data with unified cross-chain schemas ready for analytics, AI training, compliance reporting, and quantitative analysis.

Multi-Chain Coverage

All APIs support 50+ blockchains including Ethereum, Solana, Polygon, BSC, Avalanche, Arbitrum, and all major networks. Unified data formats eliminate the need to integrate with multiple chain-specific solutions or run custom indexing infrastructure.
