API Reference Introduction
Find Signal REST API endpoints, data structures, and examples organized by resource type.
Use this guide to map Signal API resource groups to the endpoint pages, schemas, and examples you need.
Use the API Reference button in the header to open the endpoint pages. There you can review endpoint paths, request parameters, response examples, and the interactive call builder tool.
What each reference page includes
- Resource overview: A summary of the resource type and the related endpoints on that page.
- Data definitions: Field-level details for request and response objects, including data types and example JSON when available.
- Operations: Supported endpoints, paths, parameters, and example requests or responses for common use cases.
Core API Sections

Start with API fundamentals, authentication, request formats, response structure, date handling, tools, and versioning.
Use Echo endpoints to validate credentials, test request formatting, validate input formats, and simulate API errors.
Use these APIs for on-demand calculations such as bill matching, rate comparisons, what-if scenarios, and project economics.
