Making API Requests

Making API requests to LBank contracts involves sending HTTP requests to specific endpoints. The API supports both RESTful and WebSocket protocols, allowing for both synchronous and asynchronous interactions. Here’s how to make a basic API request:

• Choose the endpoint: Decide which endpoint you want to call based on the operation you want to perform. For example, to get market data, you might use the /market/ticker endpoint.
• Prepare the request: Construct the HTTP request with the necessary parameters. Include your API key in the headers for authentication.
• Send the request: Use a tool like cURL or a programming language’s HTTP library to send the request to the LBank API server.
• Process the response: Once you receive a response, parse it to extract the relevant data.

• Send the request: Use a tool like cURL or a programming language’s HTTP library to send the request to the LBank API server.
• Check the response: The API will return a response indicating whether the order was placed successfully. If successful, you will receive an order ID that you can use to track the order.

Example: Retrieving Market Data

Retrieving market data is another common use case for the LBank Contracts API. Here’s how you can get the latest ticker data:

• Choose the trading pair: Decide which trading pair you want to get data for.
• Construct the API request: Use the /market/ticker endpoint and include your API key in the headers. The request should specify the trading pair.
• Send the request: Use a tool like cURL or a programming language’s HTTP library to send the request to the LBank API server.
• Parse the response: The API will return a JSON response containing the latest ticker data, including the current price, volume, and other market statistics.
