Leetcode-api

Leetcode API provides a collection of GraphQL queries to interact with Leetcode's GraphQL endpoint. These queries allow you to retrieve various data from Leetcode, such as user profiles and problem sets. This repository serves as a reference for developers who want to integrate Leetcode data into their applications or automate data retrieval processes.

Getting Started

To start using the Leetcode API GraphQL queries, you need to set up a tool or environment that can send GraphQL requests. Popular tools include:

Insomnia or Postman

Insomnia: A powerful HTTP and GraphQL client. Postman: Another versatile API client that supports GraphQL. GraphQL Clients in Code: Libraries such as requests in Python can be used to send GraphQL queries programmatically.

Insomnia http request: "https://leetcode.com/graphql/"

GraphQL Queries

1. Get User Profile

Retrieve the profile information and submission statistics of a specific Leetcode user.

Query:

query getUserProfile($username: String!) {
  matchedUser(username: $username) {
    username
    submitStats: submitStatsGlobal {
      acSubmissionNum {
        difficulty
        count
      }
    }
  }
}

Query Variables:

{
  "username": "YOUR_USERNAME"
}

2. Get Problem Set Question List

Fetch a list of problems from the Leetcode problem set with various filters.

Query:

query problemsetQuestionList($categorySlug: String, $limit: Int, $skip: Int, $filters: QuestionListFilterInput) {
  problemsetQuestionList: questionList(
    categorySlug: $categorySlug
    limit: $limit
    skip: $skip
    filters: $filters
  ) {
    total: totalNum
    questions: data {
      acRate
      difficulty
      freqBar
      frontendQuestionId: questionFrontendId
      isFavor
      paidOnly: isPaidOnly
      status
      title
      titleSlug
      topicTags {
        name
        id
        slug
      }
      hasSolution
      hasVideoSolution
    }
  }
}

Query Variables:

{
  "categorySlug": "",
  "skip": 0,
  "limit": 50,
  "filters": {}
}

Sample Responses

1. Get User Profile Response

          }
        ]
      }
    }
  }
}

2. Get Problem Set Question List Response

{
  "data": {
    "problemsetQuestionList": {
      "total": 3166,
      "questions": [
        {
          "acRate": 52.6721723918133,

          "paidOnly": false,
          "status": null,
          "title": "Two Sum",
          "titleSlug": "two-sum",
          "topicTags": [
            {

          "hasVideoSolution": true
        },
        ...
      ]
    }
  }
}
