Code examples - NexusAPI 文档中心

The examples below use OpenAI Chat Completions. First confirm the selected model and protocol in the API and model capability matrix. For optional fields and full schemas, use the Apifox API reference.

Core settings

Base URL: https://nexusapi.link/v1
API key: create it in the NexusAPI console
Model ID: copy the exact ID from the Model Marketplace for the current key’s group

Python

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://nexusapi.link/v1",
)

stream = client.chat.completions.create(
    model="YOUR_MODEL_ID",
    messages=[{"role": "user", "content": "Introduce yourself."}],
    stream=True,
)

for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="", flush=True)

JavaScript

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.NEXUSAPI_API_KEY,
  baseURL: "https://nexusapi.link/v1",
});

const stream = await client.chat.completions.create({
  model: "YOUR_MODEL_ID",
  messages: [{ role: "user", content: "Introduce yourself." }],
  stream: true,
});

for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content || "");
}

cURL

curl 'https://nexusapi.link/v1/chat/completions' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -d '{
    "model": "YOUR_MODEL_ID",
    "messages": [{"role": "user", "content": "Test that the API is reachable"}]
  }'

Do not put an actual key in source code or commit it to a repository. Image generation uses a different endpoint; see the image model guide.
