Resolution Service (1.0.0)

Unstoppable Domains (Partner Engineering): partnerengineering@unstoppabledomains.com

The Resolution Service provides APIs for resolving domain metadata and records from multiple blockchain and naming services. The service currently supports the following naming services:

  • Unstoppable Domain's UNS and CNS with TLDs: .x, .polygon, .nft, .crypto, .blockchain, .bitcoin, .dao, .888, .wallet, .binanceus, .hi, .klever, .kresus, .anime, .manga, .go, .zil

  • Ethereum Naming Service - ENS with TLDs: .eth



The service caches blockchain events in a database for easy retrieval without accessing any blockchain APIs. With the Resolution Service API, you can quickly build applications directly communicating with the blockchain to get UD domain data with a single API request.

Domains

Get domain

Get Records for a Domain
Note: The API should be used in a backend system. If you need the data in client apps, please build a proxy backend to hide the API key.
