This page will help you get started with OpenNode. You'll be up and running in a jiffy!


OpenNode offers a powerful REST API that supports bitcoin lightning network and standard on-chain operations with action events associated allowing you to receive and send microtransactions instantly.

Our API uses HTTP response codes and returns all error responses in JSON. To explore the API as much as possible, we offer a developer environment in addition to production. Any operations made in the development environment use the Bitcoin's testnet network as well as Lightning infrastructure connected to testnet full nodes.

Development and production environments require separate API Keys that can be generated in your personal dashboard settings.

We provide libraries for the following languages/frameworks: - PHP, NodeJS

There are other non-official libraries developed by the community that you might find useful.


This is currently a beta of our documentation. Let us know how we can improve our API documentation to provide the smoothest experience.
