Decarbonizing Supply Chains: How Energy API Supports Tracking and Reporting

Introduction

As the world increasingly focuses on sustainability and reducing carbon emissions, businesses are under pressure to decarbonize their supply chains. This challenge is particularly acute in the energy sector, where accurate and timely data is crucial for making informed decisions. However, accessing reliable energy market data can be a daunting task. Developers and data engineers often find themselves grappling with disparate data sources, inconsistent formats, and the complexities of scraping government portals. This is where Energy API comes into play, offering a unified solution to streamline the process of tracking and reporting energy data.

Energy API aggregates wholesale energy market data from trusted sources such as OMIE, ENTSO-E, EIA, and Ember, normalizing it into a single, easy-to-use JSON interface. This not only saves time but also enhances the accuracy of the data, enabling businesses to make better decisions in their decarbonization efforts. In this blog post, we will explore how Energy API can support your organization in tracking and reporting energy data effectively.

Why Energy API

Energy API stands out in the crowded landscape of energy data solutions for several reasons:

• Unified Data Source: Instead of dealing with multiple APIs, each with its own format and schedule, Energy API provides a single REST interface that aggregates data from various providers. This means developers can access all necessary information without the hassle of stitching together different data sources.
• Comprehensive Coverage: With over 39 symbols across six commodity categories—electricity, natural gas, crude oil, coal, carbon allowances, and carbon intensity—Energy API offers extensive market coverage. This allows users to query multiple commodities in a single API call, significantly simplifying data retrieval.
• Rapid Development: The consistent JSON schema across all commodities means that developers can implement features in hours rather than weeks. This accelerates the time to market for applications that rely on energy data.
• Trusted Data Providers: Energy API sources its data from reputable organizations, ensuring that users receive accurate and reliable information. This is crucial for businesses that need to report on sustainability metrics and comply with regulatory requirements.

Quick Start

Getting started with Energy API is straightforward. The base URL for the API is:

https://energy-api.com/api/v1

To make your first request, you will need to include your API key as a query parameter. Here’s an example of how to retrieve the latest prices for Brent Crude and TTF Gas:

curl -G https://energy-api.com/api/v1/latest \
--data-urlencode "symbols=BRENT_CRUDE,TTF_GAS" \
--data-urlencode "api_key=YOUR_API_KEY"

The expected JSON response will look like this:

{
"success": true,
"date": "2026-06-11",
"base": "MIXED",
"rates": {
"BRENT_CRUDE": 74.82,
"TTF_GAS": 38.15
