API Description

The API specification only describes the API request method and relative path. You need to run the gateway yourself or use a public gateway.

The gateway will connect the communication between the HTTP request and the blockchain, so some operations will deduct a certain amount of gas fees from the wallet specified by the gateway.

In the request example section, the GatewayURL field needs to be replaced with the server address of the gateway.

We provide some public gateways, their information is as follows:
