ISNetworld API is published by [ISN](https://apis.io/providers/isn/) on the [APIs.io](https://apis.io/) network. Tagged areas include Contractor Management, Compliance, and Supply Chain. The published artifact set on APIs.io includes authentication docs and rate-limit docs.

The ISNetworld API is a RESTful, bearer-token authenticated HTTP API that lets ISN subscribers download their own ISNetworld data — company profile scorecards, connected contractor lists and related compliance records — for integration with internal systems. A client exchanges a UserKey and CompanyKey header pair at GET /token for a bearer token, validates it at GET /validate-token, and calls versioned resource paths under /1.0/. Requests must use TLS 1.2 or later. ISN publishes no OpenAPI description and no public reference; the Developer Integration Guide is issued to subscribers and the API's own help surface at /help is authentication-gated.
