Onchain API — Data for Crypto Projects

A blockchain API is a service layer that allows developers to interact with onchain data from decentralized ecosystems. It enables structured requests (queries) for data like wallet balances, smart contract calls, transaction histories, and more. Rather than managing your own infrastructure, Nomis provides direct access through powerful API endpoints to real-time analytics and blockchain events across supported networks.

This kind of API acts as a critical bridge between crypto applications and blockchain data, making it easier to build, analyze, or automate web3 tools and services without maintaining your own node.

Whether you're building dashboards, creating web3 analytics tools, or integrating with smart contracts, the Nomis API provides efficient access to the raw onchain activity behind wallets, contracts, and tokens.

While both may serve the crypto ecosystem, there's a clear difference. A crypto API typically delivers information from centralized exchanges—like price feeds, market depth, or order books. A blockchain data API, however, focuses on direct access to the decentralized ledger, offering insights into onchain transactions, contract states, and user behavior.

Nomis operates strictly on the onchain level, delivering blockchain-native insights across wallets and contracts. It's ideal for developers seeking raw blockchain intelligence, rather than exchange-based market data.

Yes—Nomis offers real-time access to blockchain transaction data, allowing you to monitor wallet behavior, token transfers, and contract interactions as they happen. Our infrastructure ingests and processes onchain events with minimal delay, giving you the fastest route to live blockchain analytics.

This is especially helpful for crypto platforms focused on automation, reward systems, or security triggers based on live transaction flows.

Not at all. With Nomis, there’s no need to deploy or maintain your own blockchain node. We serve as the data provider, giving you immediate access to onchain metrics via our ready-to-use API endpoints.

This way, developers and businesses can focus entirely on building their blockchain-powered apps without dealing with low-level network management or uptime issues.

If you're choosing an API to power your onchain data needs, here are some essentials:

Nomis API checks all of these boxes—offering precise, actionable blockchain analytics for developers, data teams, and crypto-native platforms.
