A crypto API is a software interface that allows applications or users to access and retrieve cryptocurrency data—such as balances, prices, trades, or transactions—from exchanges, blockchains, and data aggregators in real time.

Are crypto APIs secure to use for tracking my portfolio?

Most reputable APIs use strong security measures. For exchange APIs, set read-only permissions when possible, and never share your private keys. Always review a provider's documentation and best practices before use.

Can I use crypto APIs without coding skills?

While coding offers maximum flexibility, many portfolio tracking platforms and apps utilize APIs behind the scenes to collect and display your asset data—no coding required.

What’s the difference between using a crypto API and a portfolio tracking app?

APIs are tools for collecting and sharing data, often requiring custom setup, while apps are ready-made solutions built on APIs for ease of use. Advanced users might use APIs directly for custom or automated tracking; others may prefer user-friendly apps.
