From registration to actual use - step by step
Visit OpenRouter's website and log in with Google or GitHub account. OpenRouter is an AI model aggregation platform—one API Key calls 300+ models (GPT, Claude, Llama, Gemini, etc.) without separate registrations. New users get a small free credit.
Go to Sign UpOpenRouter supports "Free Models" (e.g., Llama 3.1 8B Instruct free) for testing without payment. For production, top up at least $10 to unlock all models.
Create an API Key on the "Keys" page. The OpenRouter API is OpenAI-compatible with base_url openrouter.ai/api/v1. Add HTTP-Referer (your app URL) and X-Title (app name) in HTTP headers for stats and rankings.
Set "Spend Limit" daily budget caps to prevent overspending. Enable "Auto-recharge" to auto-top up when balance falls below threshold, avoiding app interruptions.
Specify the model parameter when calling, e.g., anthropic/claude-3.5-sonnet, meta-llama/llama-3.1-70b-instruct. Use the ":nitrous" suffix (e.g., openai/gpt-4o:nitrous) for faster response. Supports fallback routing: auto-switch to backup model if primary fails.
Use "Model Routing": {"models": ["openai/gpt-4o", "anthropic/claude-3.5-sonnet"], "data_collection": "deny"}—tries in order, auto-falls back to second if first fails.
View each call's model, token count, cost, and latency on the "Activity" page. OpenRouter bills at official prices (no markup) with transparent comparison. Compare price, context length, and capabilities on the "Models" page to select the best model.
Use Llama 3.1 8B ($0.05/M tokens) for simple tasks, Claude 3.5 Sonnet ($3/M tokens) for complex ones. Hybrid routing can reduce costs by 70%.
