How this service works
API Gateway: OpenRouter API
Output
Returns the raw OpenRouter API response for the proxied path — typically a JSON object containing the model's generated text, finish reason, and token usage counts, identical to what OpenRouter would return directly.
Example use cases
Example prompt
