Scorecard TypeScript API Library

>)

This library provides convenient access to the Scorecard REST API from server-side TypeScript or JavaScript.

The REST API documentation can be found on docs.scorecard.io. The full API of this library can be found in api.md.

It is generated with Stainless.

MCP Server

Use the Scorecard MCP Server to enable AI assistants to interact with this API, allowing them to explore endpoints, make test requests, and use documentation to help integrate this SDK into your application.

Note: You may need to set environment variables in your MCP client.

Installation

npm install scorecard-ai

Usage

The full API of this library can be found in api.md.

<!-- prettier-ignore -->

import Scorecard from 'scorecard-ai';

const client = new Scorecard({
  apiKey: process.env['SCORECARD_API_KEY'], // This is the default and can be omitted
  environment: 'staging', // or 'production' | 'local'; defaults to 'production'
});

const run = await client.runs.create('314', { metricIds: ['789', '101'], testsetId: '246' });

console.log(run.id);

Request & Response types

This library includes TypeScript definitions for all request params and response fields. You may import and use them like so:

<!-- prettier-ignore -->

import Scorecard from 'scorecard-ai';

const client = new Scorecard({
  apiKey: process.env['SCORECARD_API_KEY'], // This is the default and can be omitted
  environment: 'staging', // or 'production' | 'local'; defaults to 'production'
});

const testset: Scorecard.Testset = await client.testsets.get('246');

Documentation for each method, request param, and response field are available in docstrings and will appear on hover in most modern editors.

Handling errors

When the library is unable to connect to the API, or if the API returns a non-success status code (i.e., 4xx or 5xx response), a subclass of APIError will be thrown:

Shortened. The full README is on GitHub.
