Rate limiting restricts each client IP to 100 requests per minute per hostname across the load balancer domains. When a client exceeds the limit, the configured action is applied: `challenge` requires the visitor to pass a managed challenge for 5 minutes, `throttle` blocks requests only while the rate stays above the limit, and `ban` blocks the client IP for 5 minutes. Changes are synced to the edge network as part of the request. Returns the updated rate limit state. ## OpenAPI ````yaml https://api.sevalla.com/v3/openapi.json put /load-balancers/{id}/rate-limit openapi: 3.1.0 info: title: Sevalla API docs version: 1.0.0 servers: - url: https://api.sevalla.com/v3 security: - bearerAuth: [] paths: /load-balancers/{id}/rate-limit: put: tags: - Load balancers summary: Update rate limit description: >- Update the rate limiting configuration for a load balancer.
