Freemium · $10 one-timeOne API key and balance for GPT, Claude, Gemini and other models
What is flatkey?
flatkey routes requests to the official APIs of OpenAI, Anthropic, Google, DeepSeek, Qwen, GLM and others, and adds more than 1,000 pay-per-call tools behind a single key. Developers and startups get one balance and one invoice instead of many provider accounts.
Model pages list input and output prices per million tokens, and a compare view and playground help you test options before building. Failed calls are not charged, and the service states it does not retain request content.
Credits are bought as one-time top-ups that never expire, with bonus credit on larger amounts. Payment works by card, Pix, UPI and Alipay, and enterprise customers can contract for B300 GPU inference with custom routing and invoicing.
