/v1/chat/completions is the recommended DimiLinks chat endpoint. Its request and response structures match the official OpenAI endpoint, so you can use the OpenAI SDK directly. Set model to the name of a text model available to the current key to call Claude, GPT, or another model.

Request URL

POST https://api-direct.dimilinks.com/v1/chat/completions
Content-Type: application/json
Authorization: Bearer <DIMILINKS_API_KEY>

Basic example

curl "https://api-direct.dimilinks.com/v1/chat/completions" \
  -H "Authorization: Bearer $DIMILINKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-5",
    "messages": [
      {"role": "system", "content": "You are a concise assistant."},
      {"role": "user", "content": "Explain Pluto in one sentence."}
    ]
  }'

Response (abridged):

{
  "id": "chatcmpl_xxx",
  "object": "chat.completion",
  "created": 1777080000,
  "model": "claude-sonnet-5",
  "choices": [
    {
      "index": 0,
      "message": { "role": "assistant", "content": "..." },
      "finish_reason": "stop"
    }
  ],
  "usage": {
    "prompt_tokens": 32,
    "completion_tokens": 24,
    "total_tokens": 56
  }
}

Streaming

Add "stream": true to the request. The server returns incremental chunks as text/event-stream and ends with data: [DONE].

curl "https://api-direct.dimilinks.com/v1/chat/completions" \
  -H "Authorization: Bearer $DIMILINKS_API_KEY" \
  -H "Content-Type: application/json" \
  -N \
  -d '{
    "model": "gpt-5.5",
    "stream": true,
    "messages": [
      {"role": "user", "content": "Write a four-line poem about the deep sea."}
    ]
  }'

Each event has this structure:

data: {"id":"chatcmpl_xxx","object":"chat.completion.chunk","model":"gpt-5.5",
"choices":[{"index":0,"delta":{"content":"Far"},"finish_reason":null}]}

Parameters

The table lists common fields. Any unlisted field is passed through to the upstream provider when the model supports it.

Parameter	Type	Default	Description
`model`	string	Required	Model ID, such as `claude-sonnet-5`, `claude-opus-4-8`, `gpt-5.5`, `gpt-5.6-terra`, or `qwen3.7-max`.
`messages`	array	Required	Message array containing at least one `role=user` item. Supported roles are `system` / `user` / `assistant` / `tool`.
`stream`	boolean	`false`	When `true`, returns SSE streaming chunks.
`temperature`	number	Model default	Sampling temperature from 0 to 2.
`top_p`	number	Model default	Nucleus sampling probability from 0 to 1.
`max_tokens`	integer	Model default	Maximum tokens in one response; we recommend setting it explicitly for Claude models.
`stop`	string \| string[]	Empty	Stop generation when one of these sequences is matched.
`presence_penalty`	number	`0`	Penalty for repeating topics, from -2 to 2.
`frequency_penalty`	number	`0`	Penalty for repeating words, from -2 to 2.
`tools`	array	Empty	Tool definitions compatible with OpenAI Tool Calling.
`tool_choice`	string \| object	`auto`	Controls whether a specific tool must be called.
`response_format`	object	Empty	Requests JSON output, for example `{ "type": "json_object" }`.
`user`	string	Empty	End-user identifier for auditing and rate limiting.

Recommended models

Scenario	Models
General chat / long documents	`claude-sonnet-5`, `claude-opus-4-8`, `gpt-5.5`
Complex reasoning / coding	`claude-opus-4-8`, `kimi-k2.7-code`, `gpt-5.6-terra`
Chinese-language and general tasks	`qwen3.7-max`, `glm-5.2`, `MiniMax-M3`
Low-cost batch tasks	`claude-haiku-4-5`, `gpt-5.4-mini`, `deepseek-v4-flash`
Multimodal vision	`gpt-image-2` is dedicated to image generation. Visual chat support varies by model; first inspect `input_modalities` from `/v1/models`.

Call with the OpenAI SDK

Python:

from openai import OpenAI

client = OpenAI(
    api_key="sk-...",
    base_url="https://api-direct.dimilinks.com/v1",
)

response = client.chat.completions.create(
    model="claude-sonnet-5",
    messages=[
        {"role": "system", "content": "You are a rigorous assistant."},
        {"role": "user", "content": "Explain the Fourier transform."},
    ],
    max_tokens=1024,
)

print(response.choices[0].message.content)

Node.js:

import OpenAI from 'openai'

const client = new OpenAI({
  apiKey: process.env.DIMILINKS_API_KEY,
  baseURL: 'https://api-direct.dimilinks.com/v1',
})

const response = await client.chat.completions.create({
  model: 'gpt-5.5',
  messages: [{ role: 'user', content: 'Hello' }],
})

Tool calling

curl "https://api-direct.dimilinks.com/v1/chat/completions" \
  -H "Authorization: Bearer $DIMILINKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-5",
    "messages": [
      {"role": "user", "content": "Check the current weather in Tokyo."}
    ],
    "tools": [
      {
        "type": "function",
        "function": {
          "name": "get_weather",
          "description": "Retrieve the current weather for a city",
          "parameters": {
            "type": "object",
            "properties": {
              "city": {"type": "string"}
            },
            "required": ["city"]
          }
        }
      }
    ]
  }'

When the model returns tool_calls, execute the tool, add its result to messages as a role=tool message, and call the endpoint again.

Error handling

Failed requests return the OpenAI-style error wrapper. See Errors. If an upstream connection closes during a streaming request, the final event may not be [DONE]; treat a closed connection as a retryable error as well.
