# Capter CLI  [](https://codecov.io/gh/capterqa/cli) [](https://www.npmjs.com/package/@capterqa/cli) Capter is a lightweight **end-to-end** testing tool for APIs. It's language agnostic and can test APIs written in any language (Node.js, Go etc). - 🧑‍💻 Write tests in YAML - 🔎 Run the same tests locally, in CI, or as a cron job to monitor your live APIs - 🏃‍♂️ Takes **less than a minute** to get started ## How it works: Create a workflow file in a `.capter` folder: ```yaml # .capter/products.yml name: products steps: - name: fetch all products id: products url: ${{ env.URL }}/api/products assertions: - !expect status to_equal 200 - !expect body to_be_array - name: fetch first product url: ${{ env.URL }}/api/posts/${{ products.response.body.0.id }} assertions: - !expect body.id to_equal ${{ products.response.body.0.id }} ``` Then run the CLI: ```sh URL=http://localhost:3000 capter test ``` ## Demo  ## Getting started Follow the instructions in the documentation to get started: - [Installation](https://docs.capter.io/cli/guide/installation) - [Getting started](https://docs.capter.io/cli/guide/getting-started) ## API - [CLI reference](https://docs.capter.io/cli/reference/cli) - [Workflow reference](https://docs.capter.io/cli/reference/workflow) # License The Capter CLI is provided under the [MIT License](http://http//opensource.org/licenses/mit-license.php).
