Bitcoin-Price is a high-performance solution built in Go, designed to fetch cryptocurrency values concurrently from various REST APIs. It's engineered for efficiency and speed, utilizing Go's robust concurrency model to make multiple endpoint calls simultaneously. This project stands out for its minimalistic approach, resulting in an extremely small Docker image based on scratch, making it lightweight and fast.

• Concurrent API Calls: Leverages Go's concurrency for efficient API querying.
• Flexible Configuration: Easily configurable for fetching values of various assets, not limited to Bitcoin.
• Minimal Docker Image: Built on scratch, ensuring a small footprint.
• Robust Error Handling: Handles API rate limits and networking issues with a retry mechanism.

go build -o main .
./main

Build the Docker image:

docker build -t bitcoin-price .

Run the Docker container (ensure config.json is in your current directory):

docker run -w $(pwd) -v $(pwd):$(pwd) bitcoin-price

config.json allows adding new exchanges or assets easily. Example:

[
    {
        "exchange": "NewExchange",
        "url": "https://api.newexchange.com/price",
        "jsonPath": "price"
    }
    // ... other configurations ...
]
