About primary rate limits

GitHub limits the number of REST API requests that you can make within a specific amount of time. This limit helps prevent abuse and denial-of-service attacks, and ensures that the API remains available for all users.

Some endpoints, like the search endpoints, have more restrictive limits. For more information about these endpoints, see "REST API endpoints for rate limits." The GraphQL API also has a separate primary rate limit. See "Rate limits and node limits for the GraphQL API."

To learn about viewing an organization's API activity, including which requests exceeded primary rate limits, see "Viewing API insights in your organization."

In general, you can calculate your primary rate limit for the REST API based on your method of authentication, as described below.

Primary rate limit for unauthenticated users

You can make unauthenticated requests if you are only fetching public data. Unauthenticated requests are associated with the originating IP address, not with the user or application that made the request.

The primary rate limit for unauthenticated requests is 60 requests per hour.

Primary rate limit for authenticated users

You can use a personal access token to make API requests. Additionally, you can authorize a GitHub App or OAuth app, which can then make API requests on your behalf.

All of these requests count towards your personal rate limit of 5,000 requests per hour. Requests made on your behalf by a GitHub App that is owned by a GitHub Enterprise Cloud organization have a higher rate limit of 15,000 requests per hour. Similarly, requests made on your behalf by a OAuth app that is owned or approved by a GitHub Enterprise Cloud organization have a higher rate limit of 15,000 requests per hour if you are a member of the GitHub Enterprise Cloud organization.

Primary rate limit for GitHub App installations

GitHub Apps authenticating with an installation access token use the installation's minimum rate limit of 5,000 requests per hour. If the installation is on a GitHub Enterprise Cloud organization, the installation has a rate limit of 15,000 requests per hour.

For installations that are not on a GitHub Enterprise Cloud organization, the rate limit for the installation will scale with the number of users and repositories. Installations that have more than 20 repositories receive another 50 requests per hour for each repository. Installations that are on an organization that have more than 20 users receive another 50 requests per hour for each user. The rate limit cannot increase beyond 12,500 requests per hour.

Primary rate limits for GitHub App user access tokens (as opposed to installation access tokens) are dictated by the primary rate limits for the authenticated user. This rate limit is combined with any requests that another GitHub App or OAuth app makes on that user's behalf and any requests that the user makes with a personal access token. See "Primary rate limit for authenticated users."

Primary rate limit for OAuth apps

Primary rate limits for OAuth access tokens generated by a OAuth app are dictated by the primary rate limits for authenticated users. This rate limit is combined with any requests that another GitHub App or OAuth app makes on that user's behalf and any requests that the user makes with a personal access token. See "Primary rate limit for authenticated users."

OAuth apps can also use their client ID and client secret to fetch public data. For example:

curl -u YOUR_CLIENT_ID:YOUR_CLIENT_SECRET -I https://api.github.com/meta

For these requests, the rate limit is 5,000 requests per hour per OAuth app. If the app is owned by a GitHub Enterprise Cloud organization, the rate limit is 15,000 requests per hour.

Primary rate limit for GITHUB_TOKEN in GitHub Actions

You can use the built-in GITHUB_TOKEN to authenticate requests in GitHub Actions workflows. See "Automatic token authentication."

The rate limit for GITHUB_TOKEN is 1,000 requests per hour per repository. For requests to resources that belong to a GitHub Enterprise Cloud account, the limit is 15,000 requests per hour per repository.

About secondary rate limits

In addition to primary rate limits, GitHub enforces secondary rate limits in order to prevent abuse and keep the API available for all users.

You may encounter a secondary rate limit if you:

• Make too many concurrent requests. No more than 100 concurrent requests are allowed. This limit is shared across the REST API and GraphQL API.
• Make too many requests to a single endpoint per minute. No more than 900 points per minute are allowed for REST API endpoints, and no more than 2,000 points per minute are allowed for the GraphQL API endpoint. For more information about points, see "Calculating points for the secondary rate limit."
• Make too many requests per minute. No more than 90 seconds of CPU time per 60 seconds of real time is allowed. No more than 60 seconds of this CPU time may be for the GraphQL API. You can roughly estimate the CPU time by measuring the total response time for your API requests.
• Make too many requests that consume excessive compute resources in a short period of time.
• Create too much content on GitHub in a short amount of time. In general, no more than 80 content-generating requests per minute and no more than 500 content-generating requests per hour are allowed. Some endpoints have lower content creation limits. Content creation limits include actions taken on the GitHub web interface as well as via the REST API and GraphQL API.

These secondary rate limits are subject to change without notice. You may also encounter a secondary rate limit for undisclosed reasons.

Calculating points for the secondary rate limit

Some secondary rate limits are determined by the point values of requests. For GraphQL requests, these point values are separate from the point value calculations for the primary rate limit.

Request	Points
GraphQL requests without mutations	1
GraphQL requests with mutations	5
Most REST API GET, HEAD, and OPTIONS requests	1
Most REST API POST, PATCH, PUT, or DELETE requests	5

Some REST API endpoints have a different point cost that is not shared publicly.

Checking the status of your rate limit

You can use the headers that are sent with each response to determine the current status of your primary rate limit.

Header name	Description
x-ratelimit-limit	The maximum number of requests that you can make per hour
x-ratelimit-remaining	The number of requests remaining in the current rate limit window
x-ratelimit-used	The number of requests you have made in the current rate limit window
x-ratelimit-reset	The time at which the current rate limit window resets, in UTC epoch seconds
x-ratelimit-resource	The rate limit resource that the request counted against. For more information about the different resources, see "REST API endpoints for rate limits."

You can also call the GET /rate_limit endpoint to check your rate limit. Calling this endpoint does not count against your primary rate limit, but it can count against your secondary rate limit. See "REST API endpoints for rate limits." When possible, you should use the rate limit response headers instead of calling the API to check your rate limit.

There is not a way to check the status of your secondary rate limit.

Exceeding the rate limit

If you exceed your primary rate limit, you will receive a 403 or 429 response, and the x-ratelimit-remaining header will be 0. You should not retry your request until after the time specified by the x-ratelimit-reset header.

If you exceed a secondary rate limit, you will receive a 403 or 429 response and an error message that indicates that you exceeded a secondary rate limit. If the retry-after response header is present, you should not retry your request until after that many seconds has elapsed. If the x-ratelimit-remaining header is 0, you should not retry your request until after the time, in UTC epoch seconds, specified by the x-ratelimit-reset header. Otherwise, wait for at least one minute before retrying. If your request continues to fail due to a secondary rate limit, wait for an exponentially increasing amount of time between retries, and throw an error after a specific number of retries.

Continuing to make requests while you are rate limited may result in the banning of your integration.

Staying under the rate limit

You should follow best practices to help you stay under the rate limits. See "Best practices for using the REST API."

You can also stream the audit log in order to view API requests. This can help you troubleshoot integrations that are exceeding the rate limit. See "Streaming the audit log for your enterprise."

Getting a higher rate limit

If you want a higher primary rate limit, consider making authenticated requests instead of unauthenticated requests. Authenticated requests have a significantly higher rate limit than unauthenticated requests.

If you are using a personal access token for automation in your organization, consider whether a GitHub App will work instead. GitHub Apps used by GitHub Enterprise Cloud accounts have a higher rate limit than personal access tokens. See "About creating GitHub Apps."
