# Welcome

> _Build smarter. Ship faster._

Engrate is the acceleration layer for companies building energy products. We give you production-ready APIs for the hard parts — cost calculations, schedule submissions, settlement workflows — so you can ship in days instead of spending months on legacy integrations.

## Getting started

<Steps>
  <Step title="Sign up">
    Create an account at [console.engrate.io](https://console.engrate.io) and generate an API key.

    <Warning>
      Keep your API key secure and never commit it to version control. Use environment variables or secure secret management in production.
    </Warning>
  </Step>

  <Step title="Pick a quickstart">
    Start with the [Cost of Energy Quickstart](/guides/cost-of-energy-quickstart) to go from zero to a working cost calculation with curl examples you can paste and go.
  </Step>

  <Step title="Explore the platform">
    Browse [all products](/products) or jump straight to the [API reference](/api-reference).
