How Failover Works

Intelligent retry logic with circuit breaker pattern

01

Request Sent

Your request is sent to the primary provider based on your routing settings.

02

Failure Detected

Rate limit, timeout, or error detected within milliseconds.

03

Auto-Retry

Instantly retry with the next healthy provider from your configured list.

04

Success

Response delivered. Your user never knows there was an issue.

Circuit Breaker Protection

Smart protection that prevents cascading failures and unnecessary retry storms.

Failure Threshold

After 5 consecutive failures, the circuit opens and stops retrying that provider.

Recovery Period

After 30 seconds, the circuit half-opens to test if the provider is healthy.

Health Monitoring

Continuous monitoring restores providers to the rotation once healthy.

Circuit States

Closed (Normal)

All requests flow through normally

Half-Open (Testing)

Limited requests to test recovery

Open (Bypassed)

Requests skip this provider

Available on Team+ Plans

Automatic failover with up to 3 retry attempts is included on Team and Enterprise plans.
