About Dukou API
One API key connects your application to leading models from DeepSeek, Claude, GPT and Gemini. Use OpenAI- or Anthropic-compatible APIs, pay for what you use, and check your balance at any time.
What we do
Dukou API is a unified gateway for AI models. Point your existing client at our endpoint and choose a model; in most cases, your integration needs no other changes.
- One key, one balance: Avoid maintaining separate accounts and prepaid balances across providers.
- Compatible APIs: OpenAI and Anthropic formats work with familiar SDKs, clients and extensions.
- Clear usage records: Review input and output tokens and charges for each request in the console.
- Pay as you go: No monthly fee or minimum spend. Credits do not expire.
Why we built it
We built Dukou API to reduce the friction of trying multiple AI providers: account and payment requirements, balances scattered across services, incompatible SDK conventions, and bills that are hard to reconcile. Spend your time building; manage model access and usage in one place.
How it works
- Authenticate: We validate your API key and available balance.
- Route: We send the request to the upstream provider for the model you selected.
- Record usage: We calculate the charge from token usage and the model's listed rate, then record it against your balance.
Responses follow the compatible API format, including server-sent events (SSE) for streaming. Model names are Dukou API identifiers; see the Model Catalog for current listings. We are an independent third-party gateway, not an official provider channel.
Who it's for
- Individual developers prototyping with several models.
- Small teams seeking one usage dashboard and consolidated billing.
- AI product teams using tools such as Cursor, Continue, Cherry Studio or LobeChat.
- Anyone comparing models with the same prompt and a single API key.
Pricing
Charges are based on token usage. Input, output and supported cache usage may have different rates. The Model Catalog publishes current rates, including group multipliers. There are no hidden fees, monthly subscriptions or minimum spend. New accounts receive trial credits.
Data and security
- Request content is forwarded to provide the service; Dukou API does not use it to train models.
- You control your API keys and can revoke them or set limits.
- Credits do not expire.
- Request time, model, token usage and charges appear in usage records.
