Single provider

Single-provider routing with no failover, for dev/test or predictable single-vendor setups.

The single strategy routes every request to a single configured provider. No failover, no load balancing, and deterministic routing.

Best for: Dev/test environments or single-provider setups where you want predictable behavior.

The JSON below is a policy definition, the configuration you set when creating the routing policy, not a field on the POST /responses request body

{
  "name": "Simple OpenAI",
  "default_strategy": {
    "type": "fallback",
    "providers": [
      { "provider": "openai", "model": "gpt-5.2" }
    ]
  }
}

For production workloads, consider Priority or Intelligent routing for automatic failover and cost optimization
