How do I find my Melo API Key?

Log in to Melo, go to your Dashboard settings, and look for the API section to generate or copy your key.

What is 'on-chain' property data?

This refers to real estate information recorded on a blockchain, providing a transparent and immutable history of ownership and events.

Is my real estate data secure?

Absolutely. Your token is encrypted at rest and injected securely at runtime.
