FAQ

Common questions

Everything you need to know before getting started.

What is KeyFrog?
KeyFrog is an enterprise AI API infrastructure platform. We provide a unified API gateway that connects to 200+ AI models from OpenAI, Anthropic, Google, DeepSeek, and other providers. It's not a chat application — it's API infrastructure for developers and enterprises to build AI-powered products.
How is KeyFrog different from using OpenAI directly?
KeyFrog provides one API key and one balance to access 200+ models across multiple providers. You get automatic failover, unified billing, and up to 20% cost savings compared to managing individual provider accounts. The model responses are identical — we route your requests directly to the provider.
Do I need to change my existing code?
No. KeyFrog is fully compatible with the OpenAI Python and Node.js SDKs. Change the base_url to https://api.keyfrog.top/v1 and use your KeyFrog API key. Function calling, streaming, and tool use all work identically.
What payment methods do you accept?
We accept Visa, Mastercard, Alipay, WeChat Pay, and corporate bank transfers. Top-ups are instant and credits never expire.
Is there a monthly fee or subscription?
No. KeyFrog is purely pay-as-you-go. Top up a balance (minimum $5) and pay only for the API usage you incur. No recurring charges, no commitments.
Do you store my prompts or responses?
No. We operate a zero data retention policy. Requests are encrypted in transit and immediately forwarded to the model provider. We only log usage metrics (token counts) for billing.
