FAQ

Common questions

How does KissAPI work?

KissAPI provides a unified API gateway that routes your requests to various AI model providers. You use a single API key and OpenAI-compatible format to access models from Anthropic, OpenAI, Google, and more. We handle authentication, load balancing, and failover automatically.

Is it compatible with my existing code?

Yes. KissAPI uses the OpenAI-compatible API format. If your application already works with OpenAI's API, you only need to change the base URL and API key. Works with popular tools like Cursor, Claude Code, Cherry Studio, and any OpenAI SDK.

How is billing calculated?

You pay per token consumed, just like the original providers. Prices are displayed in USD on your dashboard. Top up your balance anytime — no subscriptions or recurring charges. You can monitor your usage in real-time from the dashboard.

What happens if a model provider goes down?

KissAPI uses multi-channel routing with automatic failover. If one upstream channel experiences issues, your requests are automatically routed to healthy alternatives, ensuring minimal disruption to your workflow.

Do you store my prompts or responses?

We log request metadata (model, tokens, timestamps) for billing purposes only. We do not store, read, or analyze the content of your prompts or model responses. See our Privacy Policy for full details.
