Introduction

The http AVR Plugin​

You can make HTTP requests to any external API from your smart contract, receive responses asynchronously, and process the data within the contract.

To achieve this, call the x/async precompile and use the http AVR Plugin. The http Plugin supports multiple APIs, so in this sense it includes multiple AVRs.

Follow tutorials in this section to learn how to do the following:

  • Implement HTTP requests and process asynchronous responses
  • Extract data from JSON responses using the JSON precompile
  • Make multiple requests to an API

JSON parsing​

Responses from HTTP requests are returned as JSON data. To extract specific values from these responses, you can use the JSON precompile, which provides a convenient way to parse JSON data within your smart contract.

Parsing data requires using the read() function of the precompile, as shown in Extract data.
