LiteGrid

The up-to-date LiteGrid API Documentation is at https://developers.tron.network/docs/lite-grid-intro.

Introduction

LiteGrid provides LITE clients running in the cloud, so you don't have to run one yourself to work with LITE on your next project.

LiteGrid offers an easy to use hosted API, load balanced full nodes, secure and reliable developer tools with direct access to the LITE Network.

LiteGrid uses a set of NodeJS apps to talk with Redis and PostgreSQL to provide a simple, fast and reliable query interface for the Lite API.

LiteGrid supports 2 types of api:

  • FullNode & SolidityNode api

LiteGrid supports all the FullNode and SolidityNode api calls, you only need to add the url: https://api.trongrid.io/, like:

https://api.trongrid.io/wallet/getnowblock

  • LiteGrid v3 (TG3) api version

As this is the first iteration of the improved LiteGrid, it starts with v1. Example: https://api.trongrid.io/v1

Parameters, Queries, & Return Values

  • Addresses in TG3 can be passed in base58 or hex formats.
  • Query parameters can be passed in camelCase or snake_case.
  • All returned JSON properties will be in snake_case (at the first level at least).
  • NB: In this document, we will primarily use base58 and snake_case formats.

Account APIs

Default 20. Max 200. fingerprint The fingerprint of the last transaction returned by the previous page. order_by Pre sorts the results during the query. order_by=block_number,asc, order_by=block_timestamp,desc. min_block_timestamp The minimum transaction timestamp default 0. max_block_timestamp The maximum transaction timestamp default now.
