Query API

Query API

Query API is an Advanced API's collection of methods that comes as a unique feature along with other extensive capabilities provided to our Premium Plan users.

Query API is an access-ready solution that enables your projects to interact with multiple blockchains in a single request. By indexing blockchain data on all supported chains, searching through large amounts of data is easier and faster than ever before. Query API can boast almost instantaneous processing speeds (due to the key-value filtering supported) for the searches that might ordinarily take hours to process.

Query API serves to request info on the ranges of blocks (max range is 100) for a full list of block metadata.

Query API implements the JSON-RPC 2.0 specification (opens in a new tab) for interaction.

Query API Methods

Query API consists of the following methods to request info on the ranges of blocks (max range is 100) for a full list of block metadata:
