    Resource limitations

    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 v4 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.
