OpenRouter to Inworld

If you are already using OpenRouter, migrating to Inworld Router is straightforward. Our API is designed to be a drop-in replacement for OpenAI-compatible endpoints, with additional features for enterprise reliability and cost optimization.

Key Differences

Feature	OpenRouter	Inworld Router
Authentication	API Key (Bearer)	API Key & Secret (Basic Auth)
Base URL	`https://openrouter.ai/api/v1`	`https://api.inworld.ai/v1`
Model Names	`provider/model`	`provider/model` (e.g., `openai/gpt-5`)
Routing	Handled via model string	Handled via `model: "auto"` or custom Routers

Migration Steps

1. Update Authentication

OpenRouter uses a single API key. Inworld uses a Key/Secret pair. OpenRouter:

Authorization: Bearer $OPENROUTER_API_KEY

Inworld:

Authorization: Bearer <your-api-key>

2. Update the Base URL

Change your client configuration to point to our endpoint.

# From:
# base_url="https://openrouter.ai/api/v1"
# To:
base_url="https://api.inworld.ai/v1"

3. Map Your Models

Inworld supports the same provider/model syntax you’re used to.

openai/gpt-5 → openai/gpt-5
anthropic/claude-opus-4-6 → anthropic/claude-opus-4-6
google-ai-studio/gemini-2.5-flash → google-ai-studio/gemini-2.5-flash

4. Enable Intelligent Routing

Instead of manually picking models, you can now use our routing engine.

{
  "model": "auto",
  "extra_body": {
    "sort": ["price", "latency"]
  }
}

Why Migrate?

Enterprise Reliability: Built-in automatic failover across providers.
Cost Optimization: Dynamic tiering to reduce bills by up to 70%.
Unified Observability: Detailed logs and performance metrics across all models.
