Rate Limiting

The Rate Limiting API lets you define rate limits and write code around them in your Worker.

You can use it to enforce:

• Rate limits that are applied after your Worker starts, only once a specific part of your code is reached
• Different rate limits for different types of customers or users (ex: free vs. paid)
• Resource-specific or path-specific limits (ex: limit per API route)
• Any combination of the above

The Rate Limiting API is backed by the same infrastructure that serves rate limiting rules.

Note

You must use version 3.45.0 or later of the Wrangler CLI.
