Unofficial ENTSO-e REST API Client for Deno and Node. Comprehensive. User-friendly. Minimalistic.

Module type: CJS+ESM NPM Downloads MIT License


  • Supports all requests listed in Entso-e REST API Documentation
  • Supports zip-file endpoints and transparently unzips documents
  • Includes examples that support both Deno and Node
  • Supports both Deno and Node (>=18.0)
  • Written in fully typed TypeScript
  • Offers ESM (for Deno and Node) and CommonJS (for Node) support
  • Adds descriptions to codes while parsing the documents


Make sure to use a recent version of your runtime. Node.js >=18 and Deno >=1.26 are supported.


import { QueryConfiguration } from "";


npm install entsoe-api-client --save

Note Using an older version of Node.js? Use 0.x versions of this library for fetch compatibility.


The structure of the documents and the parameters returned by this library closely resemble what you can find in the ENTSO-e REST API documentation. It is recommended that you also take a look there.

If you want a Publication_MarketDocument, the corresponding function in this library is queryPublication. In the resulting document (object), the key receiver_MarketParticipant.mRID will become receiverMarketParticipantId. The same transformation applies to the parameters. We recommend enabling auto-completion in your editor, as the types will provide great help in navigating the parameters and document objects.

Another difference compared to the source documents is that most IDs automatically come with a complementary description, where applicable. For example, <businessType>B33</.. in the raw XML will result in the keys businessType: “B33” and businessTypeDescription: “Area Control Error” in the output.
