OpenRouter

OpenRouter is a unified API gateway that gives WednesdayAI access to 200+ models from Anthropic, OpenAI, Google, Mistral, Meta, and many others — all from a single API key with a single billing account.

​
When to use OpenRouter

  • You want to experiment with many models without managing separate API keys
  • You need automatic fallback when a provider is down
  • You want unified billing across providers
  • You want access to models not available in your region

​
Authentication

Obtain an API key from openrouter.ai/keys. 
openclaw login
# choose: OpenRouter
# enter your API key when prompted
Or set the environment variable: 
export OPENROUTER_API_KEY=sk-or-v1-...
Lookup order:
SourceKey / path
Environment variableOPENROUTER_API_KEY
Stored credential~/.openclaw/credentials/openrouter

​
Selecting a model

OpenRouter model IDs use a provider/model format, prefixed with openrouter/: 
{
  agents: {
    defaults: {
      model: "openrouter/anthropic/claude-opus-4-6",
    }
  }
}

Run openclaw status --providers to list models your key can access.

​
Automatic fallback

OpenRouter supports provider fallback — if one provider is overloaded or down, it routes to another. This is configured in your OpenRouter account dashboard, not in WednesdayAI itself.

​
Troubleshooting

API key is invalid. Re-run openclaw login and enter a fresh key from openrouter.ai/keys.
Not all models are available to all account tiers. Check openrouter.ai/models to confirm your key has access to the model you selected.
OpenRouter adds a routing hop. If latency is a concern, consider connecting to the provider directly. Use OpenRouter for experimentation and fall back to direct connections for production.
OpenRouter may proxy to a different provider version than expected. Check openrouter.ai/models to see which backend a model ID resolves to.
