API Integration

Integrate AI models running on Clore.ai into your applications

💡 Recommended: Use the official clore-ai Python SDK instead of raw HTTP requests for managing Clore.ai servers and orders. Built-in rate limiting, retries, type safety, and async support.

Integrate AI models running on CLORE.AI into your applications.

Deploy API servers at CLORE.AI Marketplace.

Quick Start

Most AI services on CLORE.AI provide OpenAI-compatible APIs. Replace the base URL and you're ready.

from openai import OpenAI

client = OpenAI(
    base_url="http://<your-clore-server>:8000/v1",
    api_key="not-needed"  # Most self-hosted don't require key
)

response = client.chat.completions.create(
    model="meta-llama/Llama-3.1-8B-Instruct",
    messages=[{"role": "user", "content": "Hello!"}]
)
print(response.choices[0].message.content)

---

LLM APIs

vLLM (OpenAI Compatible)

Server setup:

python -m vllm.entrypoints.openai.api_server \
    --model meta-llama/Llama-3.1-8B-Instruct \
    --host 0.0.0.0 --port 8000

Python client:

from openai import OpenAI

client = OpenAI(base_url="http://server:8000/v1", api_key="dummy")

# Chat completion
response = client.chat.completions.create(
    model="meta-llama/Llama-3.1-8B-Instruct",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Write a poem about coding"}
    ],
    temperature=0.7,
    max_tokens=500
)
print(response.choices[0].message.content)

# Streaming
stream = client.chat.completions.create(
    model="meta-llama/Llama-3.1-8B-Instruct",
    messages=[{"role": "user", "content": "Tell me a story"}],
    stream=True
)
for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)

Node.js client:

import OpenAI from 'openai';

const client = new OpenAI({
    baseURL: 'http://server:8000/v1',
    apiKey: 'dummy'
});

async function chat(message) {
    const response = await client.chat.completions.create({
        model: 'meta-llama/Llama-3.1-8B-Instruct',
        messages: [{ role: 'user', content: message }]
    });
    return response.choices[0].message.content;
}

// Streaming
async function streamChat(message) {
    const stream = await client.chat.completions.create({
        model: 'meta-llama/Llama-3.1-8B-Instruct',
        messages: [{ role: 'user', content: message }],
        stream: true
    });

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

cURL:

curl http://server:8000/v1/chat/completions \
    -H "Content-Type: application/json" \
    -d '{
        "model": "meta-llama/Llama-3.1-8B-Instruct",
        "messages": [{"role": "user", "content": "Hello!"}]
    }'

Ollama API

Python:

import requests

# Generate
response = requests.post('http://server:11434/api/generate', json={
    'model': 'llama3.2',
    'prompt': 'Why is the sky blue?',
    'stream': False
})
print(response.json()['response'])

# Chat
response = requests.post('http://server:11434/api/chat', json={
    'model': 'llama3.2',
    'messages': [
        {'role': 'user', 'content': 'Hello!'}
    ],
    'stream': False
})
print(response.json()['message']['content'])

# Streaming
response = requests.post('http://server:11434/api/chat', json={
    'model': 'llama3.2',
    'messages': [{'role': 'user', 'content': 'Tell me a story'}],
    'stream': True
}, stream=True)

for line in response.iter_lines():
    if line:
        data = json.loads(line)
        print(data['message']['content'], end='', flush=True)

Ollama also supports OpenAI format:

from openai import OpenAI

client = OpenAI(base_url='http://server:11434/v1', api_key='ollama')
# Use same code as vLLM examples

TGI API

Python:

import requests

# Generate
response = requests.post('http://server:8080/generate', json={
    'inputs': 'What is machine learning?',
    'parameters': {
        'max_new_tokens': 200,
        'temperature': 0.7,
        'do_sample': True
    }
})
print(response.json()['generated_text'])

# Streaming
response = requests.post('http://server:8080/generate_stream', json={
    'inputs': 'Explain quantum computing',
    'parameters': {'max_new_tokens': 500}
}, stream=True)

for line in response.iter_lines():
    if line:
        data = json.loads(line.decode().replace('data:', ''))
        print(data.get('token', {}).get('text', ''), end='', flush=True)

        'height': height,
        'sampler_name': 'DPM++ 2M Karras',
        'cfg_scale': 7
    })

    # Decode base64 image
    image_data = base64.b64decode(response.json()['images'][0])
    return Image.open(BytesIO(image_data))

# Generate
image = txt2img(
    prompt="A beautiful sunset over mountains, photorealistic, 8k",
    negative_prompt="blurry, low quality"
)
image.save("output.png")

# img2img
def img2img(prompt, image_path, denoising=0.5):
    with open(image_path, 'rb') as f:

Best Practices

1. Connection pooling - Reuse HTTP connections

2. Async requests - Use aiohttp for concurrent calls

3. Timeouts - Always set request timeouts

4. Retry logic - Handle temporary failures

5. Rate limiting - Don't overwhelm the server

6. Health checks - Monitor server availability

---

Next Steps

• Batch Processing - Process large workloads

• Multi-GPU Setup - Scale your deployment

• LLM Comparison - Choose the right server
