Use this as a router, not a second copy of ECNU's parameter tables. Open the page for the requested capability; there is no prerequisite to read every page. The small local recipes cover integration details that otherwise get rediscovered.
| Client / integration | Base or full URL |
|---|---|
| OpenAI-compatible | https://chat.ecnu.edu.cn/open/api/v1 |
| Anthropic-compatible base | https://chat.ecnu.edu.cn/open/api/anthropic |
| Anthropic messages | https://chat.ecnu.edu.cn/open/api/anthropic/v1/messages |
| Embed ticket endpoint | https://chat.ecnu.edu.cn/open/api/embed/app |
Do not concatenate the Anthropic path onto the OpenAI base. Keep credentials in environment variables; ticket URLs are also credentials.
| Task | Official documentation | Local addition when needed |
|---|---|---|
| Chat, streaming, tools, image understanding | Chat Completions | Thinking/tool history |
| Responses-compatible client | Responses | Verify the specific advanced tool/event support; compatibility alone is insufficient |
| JSON Schema or JSON object output | Structured output | Check completion, parse raw JSON, and validate the supplied schema; do not hide a mismatch by stripping fences |
| Text or multimodal embeddings | Vectors | Text LangChain recipe or VL payloads; dimensions are model-specific |
| Text or multimodal rerank | Rerank | VL payloads; use the endpoint's contract, not an assumed OpenAI SDK method |
| Image generation | Images | Generation/edit differences; original and revised prompts can differ |
| Edit an existing image | Image edits | Multipart recipe; one uploaded image, original instruction, no output-size control |
| Text-to-speech | Audio | Non-JSON errors and PCM headers |
| Model discovery | Models endpoint | A visible ID does not prove usable capability or valid authentication |
| Anthropic-compatible client | Anthropic API | SDK setup; investigate suffix errors only when they occur |
| Embed an iframe | Embed integration | Do not log or reuse one-time tickets |
| Browser link that submits a question | URL chat | Opening a submit link sends data; do not auto-open it as a documentation check |
Use model/account pointers for models, thinking, current pricing, quotas, credentials, data handling, and release notes. Do not maintain duplicate copies of those changing tables here.
When documentation and behavior disagree, use the matching dated deviation. The current official page is the contract; a dated observation describes one tested environment. Neither a model card nor an accepted over-limit request establishes an ECNU API limit.
