Openrouter charges

What is Openrouter?

OpenRouter, Inc. operates an AI infrastructure platform that aggregates access to third-party large language model APIs, allowing developers and enterprises to switch between models from providers such as OpenAI, Anthropic, Google, Meta, and Mistral without changing their integration. Founded in early 2023 as the first LLM marketplace, the platform emphasizes anti-vendor-lock-in, higher uptime, and transparent pricing. OpenRouter operates on a credit-based, pay-as-you-go model where users purchase credits and are charged variable per-token rates depending on the model used. A 5.5% platform fee (with a minimum of $0.80) is applied at the time of credit purchases, with no fixed subscription plans or long-term contracts required.
