HiLinkup API documentation

HiLinkup provides a unified model API with OpenAI Responses, Chat Completions, Claude Messages, and Gemini generateContent compatible protocols. Use Responses for new OpenAI-style code; use the protocol that each third-party client actually supports.

API base URL: https://api.hilinkup.com/v1

Make your first request

Create an API key and send a Responses request.

Migrate from OpenAI

Reuse an existing OpenAI SDK integration.

Connect an application

Configure developer tools, chat clients, and frameworks.

Troubleshoot errors

Resolve authentication, rate-limit, and upstream errors.

Minimal example

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_HILINKUP_API_KEY",
    base_url="https://api.hilinkup.com/v1",
)

response = client.responses.create(
    model="aliyun/kimi-k3",
    input="Hello",
)
print(response.output_text)

Call GET /v1/models before choosing a model. Availability can vary by account and provider channel.

Chat Completions remains available for existing applications and chat clients that do not implement Responses.
