Chat Completions

Chat Completions API

The Chat Completions API enables you to generate conversational responses from AI models. It supports multi-turn conversations, system prompts, and various output formats.

Basic Usage

const response = await fetch('https://api.llm.catlove.cc/v1/chat/completions', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    model: 'gpt-4o',
    messages: [
      { role: 'system', content: 'You are a helpful assistant.' },
      { role: 'user', content: 'Hello!' }
    ],
  }),
});

const data = await response.json();
console.log(data.choices[0].message.content);

Streaming

For real-time responses, enable streaming:

const response = await fetch('https://api.llm.catlove.cc/v1/chat/completions', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    model: 'gpt-4o',
    messages: [{ role: 'user', content: 'Tell me a story' }],
    stream: true,
  }),
});

const reader = response.body.getReader();
while (true) {
  const { done, value } = await reader.read();
  if (done) break;
  // Process streaming chunks
}
