Enable rate limiting for a headerv3.14+
Protect your LLM services with header rate limiting. The AI Rate Limiting Advanced plugin will analyze query costs and token response to provide an enterprise-grade rate limiting strategy.
In this example, we’re rate limiting based on a specific header value. The header name is specified in the config.policies.match.key field, and the values in config.policies.match.value.
Prerequisites
- AI Proxy Advanced plugin configured with an LLM service
Environment variables
-
HEADER_NAME: The name of the header. -
HEADER_VALUE: The value of the header to rate limit.
Add this section to your kong.yaml configuration file:
