About OpenRouter
OpenRouter is an AI infrastructure and routing platform that provides a single API to access many different large language models (LLMs) and AI providers. Developers and businesses use OpenRouter to compare models, optimize cost and quality, and integrate AI features into their products without managing multiple separate vendor integrations. The service typically operates on a usage-based pricing model, where you are billed based on the volume of API calls and tokens processed.
A charge from OpenRouter on your card statement usually indicates that an API key associated with your account was used to make AI model requests, either for development, testing, or in production within an app or service you operate. This can be a one-time top‑up, a pay‑as‑you‑go usage charge over a given period, or recurring if you have set up ongoing usage that bills at regular intervals. In some cases, you may see small temporary authorization holds when adding or updating a payment method, which should clear automatically.
If you have questions about a charge, start by logging into your OpenRouter account and reviewing your billing or usage dashboard, where you can see detailed breakdowns by date, model, and application. Verify that your API keys are secure and check if any team members or connected applications may have generated usage. For issues like suspected unauthorized activity, refunds, or billing errors, you can contact OpenRouter through the support or help links on their website, including email or in‑dashboard support channels, and provide the date, amount, and last 4 digits of the card so they can investigate the transaction.
