To use the BTC Markets API, you must authenticate using an API key. This key is generated within your BTC Markets account settings and is required for making API requests. It ensures secure access and helps prevent unauthorized use. The authentication process involves including your API key in the request headers or parameters.

Key Endpoints

   • /ticker – Get the current ticker information for a specific trading pair.
   • /orderbook – Access the order book for a specific trading pair.
   • /trades – Fetch recent trade data for a particular pair.

2. Trading Endpoints
   To place and manage trades, use the following endpoints:

   • /order – Submit a new order or query an existing one.
   • /order/{id} – Retrieve details of a specific order.
   • /order/cancel/{id} – Cancel a previously placed order.

3. Account Endpoints
   Manage your account and check balances with these endpoints:

Rate Limits

BTC Markets API has rate limits to ensure fair usage and prevent abuse. Typically, limits are defined in terms of requests per minute or per second. Be sure to consult the API documentation for the specific rate limits applicable to each endpoint to avoid exceeding them and potentially facing temporary bans.

Error Handling

When interacting with the API, you may encounter errors. Common HTTP status codes and their meanings include:

• 200 OK – The request was successful.

Implement proper error handling in your application to gracefully manage these situations and ensure robust functionality.

Example Use Case

Let's consider a scenario where you want to fetch the latest price of Bitcoin against the Australian Dollar. Here’s how you might use the API:

1. Request
   Send a GET request to the /ticker endpoint with the trading pair parameter set to btcusd:

   bash
   GET /ticker?market=BTC-AUD
   

2. Response
   The API responds with a JSON object containing the current price, volume, and other relevant data:

   json
   {
     "market": "BTC-AUD",
     "price": "34000.00",
     "volume": "100.00"
   }
   

   In this example, the current price of Bitcoin is 34,000 AUD.

Best Practices

1. Security
   Always keep your API key secure. Do not expose it in client-side code or public repositories.

2. Rate Limiting
   Monitor and respect the API rate limits to prevent disruptions in service.

3. Data Handling
   Implement proper data parsing and validation to handle the JSON responses effectively.

Conclusion
