FAQ

Questions people ask before integrating

What is Tutujin API?

We supply model APIs to companies that build AI products: 739 models including GPT, Claude, Gemini, DeepSeek and Qwen, all called through one OpenAI-compatible endpoint. We don't build end-user AI apps ourselves.

How is it billed? Is there a monthly fee or minimum spend?

You pay as you go. There is no monthly fee and no minimum spend commitment, and ¥1 buys ¥1 of credit. Chat models are billed per token, with input, output and cache reads/writes priced separately; per-request models such as image generation are billed per request.

Why does one model have several prices?

A model usually sits in several groups, and each group is a different route: official relay, cloud provider, or mixed sources that include non-official ones. Different sources mean different prices. Every group is labelled with its source, and you choose one when you create an API key.

Which API formats are supported?

The OpenAI-compatible format (Chat Completions and Responses), Claude's native /v1/messages and Gemini's native generateContent. Image generation and editing, embeddings, rerank, speech and transcription are available too.

Where can I see what each call cost?

The Logs page in the console lists every call with its model, token count and cost.

Can I limit what an API key can spend or call?

Yes. Each key can have its own spending cap, expiry date, model allowlist and IP allowlist, and it uses the group you assign.

Do you store the content of my requests?

Usage logs record call details only: time, model, group, key name, token counts, cost and latency. Request and response bodies are not written to usage logs. To generate a response, your request is forwarded to the model provider behind the group you chose. See the Security & compliance page for details.

How do I top up? Can companies buy in bulk?

Top up online (as shown in the console) or buy redemption codes offline through support. For bulk purchases, add our support on WeChat.

Can you issue invoices?

Yes. We issue both China domestic invoices (fapiao) and overseas invoices: add our WeChat support and send your order number.
