Using the API

The API doesn't require any form of authorization and can easily be accessed via https://li.quest. However, optional API keys will give you access to custom rate limits.

As an integrator, you can monetize your LI.FI API integration and collect fees. See our monetization guide for more information.

Contact our business partnerships team to discover how you can partner with us and integrate LI.FI into your platform.

If your application exceeds our default rate limits, reach out to us via our partners support system to apply for API keys with custom rate limiting.
