What’s in the REST API Reference Section

This section has the main details about each of the APIs in our Genability Signal product, including their endpoints, and the data structures that are passed in and come out. Our APIs are organized into logical groups that put together common resource types and endpoints.

Switch product users. Your developer documentation has moved over to the switchsolar.io website.

How we structure each page

Each page starts with an overview of that page’s resource type and related endpoints. This lets you know if you are in the right page. Next up is a Data Definition section. This tells you in detail what fields are returned, what their data type is, and what is typically contained in them. There will usually be an example in JSON too. Then the page will have an Operations section that shows the endpoints available and the path and parameters supported for each endpoint. You’ll find a number of examples that show the request and sometimes response for common use-cases.

How APIs are grouped

The following table shows how we’ve logically group our APIs on this site. We’ve also added a column for whether the API is built into the Data Explorer web application (most but not all are). When the entry is “Partial”, only some of the APIs are integrated into Data Explorer.

APIs Overview Data Explorer Signal API
Calculation APIs On demand calculators (rate engine) for bill matching, rate comparisons, what ifs and project economics Partial1 Yes
Tariff APIs All our utility, tariff, TOU, calendar and related data Yes Yes
Other APIs Other useful APIs such as Typical usage and property meta-data Partial2 Yes
  1. Only the On-demand Cost Calculator, not the Mass Calculator
  2. The typical usage data is available to use in the calculator, but not to browse in a UI
