Introduction to Law Insider APIs

Welcome to the Law Insider API Hub. You'll find comprehensive guides and documentation to help you start working with Law Insider API as quickly as possible, as well as support if you get stuck. Let's jump right in!


The Law Insider API gives you API access to the same documents as the online Law Insider search https://www.lawinsider.com/search. The API is provided so you can build this same search function in your own product or otherwise use it from your own programs. In fact, the easiest way to construct API calls is to first run the search online then copy the general search criteria. We show how to do that here.

The search has its own syntax. But it uses the same concepts and terms you would find in most other search tools, including:

  • match exact phrase
  • and/or
  • exclude
  • fuzzy—approximate to handle variations in spelling, etc.
  • scan entire document, i.e., treat it as a flat object, or just search certain sections of document, i.e., treat part of it as a hierarchical document
  • proximity or slop, i.e., words within a stated distance from each other.
