Developer API

You can call the same endpoint we use for the website and the browser extension, directly from your own program. Free, no key required for now -- just a reasonable rate limit to protect the service for everyone.

Current phase: open access, no registration. In the future we may introduce API keys and a paid tier for heavy commercial use -- light/testing use will remain free regardless.

Parameters

address (string, required)
