All of the Wood Mackenzie Data APIs are organized around REST - if you've interacted with a RESTful API already, many of the concepts will be familiar to you. All Data API calls to Wood Mackenzie should be made to the https://api.genscape.com base domain. We use many standard HTTP features, like HTTP Get and Post verbs, which can be understood by many HTTP clients. JSON, XML or CSV can be returned in all responses from the API, including errors. The Data APIs are designed to have predictable, straightforward URLs and to use HTTP response codes to indicate API errors.
