Choosing a Protocol

Chuizi.AI currently exposes three public protocol entrypoints. Authentication, balance, rate limits, and billing are shared. Choose the protocol that matches your SDK or tool.

Situation	Protocol	Base URL
OpenAI SDK, LangChain, most tools	OpenAI compatible	`https://api.chuizi.ai/v1`
Claude Code, Cursor, Cline, OpenCode	Anthropic compatible	`https://api.chuizi.ai/anthropic`
Google AI / Gemini SDK	Gemini compatible	`https://api.chuizi.ai/gemini`

OpenAI Example

terminal

bash

curl -X POST https://api.chuizi.ai/v1/chat/completions \
  -H "Authorization: Bearer ck-your-key" \
  -H "Content-Type: application/json" \
  -d '{"model":"openai/gpt-4.1","messages":[{"role":"user","content":"Hello"}]}'

Anthropic Example

terminal

bash

curl -X POST https://api.chuizi.ai/anthropic/v1/messages \
  -H "x-api-key: ck-your-key" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{"model":"claude-sonnet-4-6","max_tokens":1024,"messages":[{"role":"user","content":"Hello"}]}'

Gemini Example

terminal

bash

curl -X POST "https://api.chuizi.ai/gemini/v1beta/models/gemini-2.5-flash:generateContent" \
  -H "x-goog-api-key: ck-your-key" \
  -H "Content-Type: application/json" \
  -d '{"contents":[{"role":"user","parts":[{"text":"Hello"}]}]}'

Protocol compatibility does not expose sensitive routing details publicly. The gateway may handle authentication, permissions, billing, routing, and format adaptation behind the scenes while the client keeps using the documented protocol.
