API 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 rate limits apply. For more information, see Rate limits for the REST API and Rate limits and query limits for the GraphQL API in the GitHub Free documentation.
