Perform Query

In this guide, we will walk you through the steps to perform a query on a REST endpoint to retrieve onchain data.

​

Prerequisites

Before you begin, ensure you have the following:

• An API key
• A REST client (e.g., Postman, curl)

​

Steps to Perform a Query

1. Identify the endpoint URL: The base URL for the API is https://data-api.cloud.ormi.dev/.
2. Add the endpoint path: Append the specific endpoint path to the base URL, e.g., {chainName}/v1/address/{walletAddress}/balance.
3. Include query parameters: Add any necessary query parameters to the URL, e.g., ?param1=value1&param2=value2.
4. Set up headers: Include the required headers, such as Authorization with your API key.
5. Make the request: Use your REST client to send a GET request to the constructed URL.
