Rate limits and node limits for the GraphQL API

The GitHub GraphQL API has limitations in place to protect against excessive or abusive calls to GitHub's servers.

Node limit

To pass schema validation, all GraphQL API calls must meet these standards:

  • Clients must supply a first or last argument on any connection.
  • Values of first and last must be within 1-100.
  • Individual calls cannot request more than 500,000 total nodes.

Calculating nodes in a call

These two examples show how to calculate the total nodes in a call.

  1. Simple query:

    query {
      viewer {
        repositories(first: 50) {
          edges {
            repository:node {
              name
    
              issues(first: 10) {
                totalCount
                edges {
                  node {
                    title
                    bodyHTML
                  }
                }
              }
            }
          }
        }
      }
    }

    Calculation:

    50         = 50 repositories
     +
    50 x 10  = 500 repository issues
    
                = 550 total nodes
  2. Complex query:

    query {
      viewer {
        repositories(first: 50) {
          edges {
            repository:node {
              name
    
              pullRequests(first: 20) {
                edges {
                  pullRequest:node {
                    title
    
                    comments(first: 10) {
                      edges {
                        comment:node {
                          bodyHTML
                        }
                      }
                    }
                  }
                }
              }
    
              issues(first: 20) {
                totalCount
                edges {
                  issue:node {
                    title
                    bodyHTML
    
                    comments(first: 10) {
                      edges {
                        comment:node {
                          bodyHTML
                        }
                      }
                    }
                  }
                }
              }
            }
          }
        }
    
        followers(first: 10) {
          edges {
            follower:node {
              login
            }
          }
        }
      }
    }

    Calculation:

    50              = 50 repositories
     +
    50 x 20       = 1,000 pullRequests
     +
    50 x 20 x 10 = 10,000 pullRequest comments
     +
    50 x 20       = 1,000 issues
     +
    50 x 20 x 10 = 10,000 issue comments
     +
    10              = 10 followers
    
                     = 22,060 total nodes

Primary rate limit

Rate limits are disabled by default for GitHub Enterprise Server. Contact your site administrator to confirm the rate limits for your instance.

If you are a site administrator, you can set rate limits for your instance. For more information, see "Configuring rate limits."

If you are developing an app for users or organizations outside of your instance, the standard GitHub.com rate limits apply. For more information, see "Rate limits and node limits for the GraphQL API" in the GitHub Free documentation.
