OpenRouter: Quick Setup for Multi-Model API Access

OpenRouter lets you call different language models—GPT-4, Claude, Mistral, DeepSeek, and several free LLMs—through one API endpoint. Here’s the streamlined way to put it to work in Make.com, Zapier, or any script.

• Go to openrouter.ai, create an account (or log in), and verify your email. • If you plan to use paid models, add credits in the Billing tab; free models are clearly marked and work within usage limits. • Open API Keys, click Generate, and copy the key. • In Make.com, Zapier, or a curl script, set the base URL to https://api.openrouter.ai and include your key in the Authorization header (Bearer YOUR_KEY_HERE). • Pick a model name—GPT-4, Claude-3, or any entry labeled [Free]—and pass it in the model parameter of your API call. • Test a simple request to confirm the connection, then build the rest of your scenario. • Check the Activity tab to watch token usage and cost so you can adjust models or prompt sizes before limits are reached.

That’s all: one key, many models, and a single place to keep track of what you’re spending. Advance your AI skills with our Udemy course – https://www.udemy.com/course/singularity-ai-for-engineers/?referralCode=75D71AF4C0EADB8975FF
