Drop-in replacement for the Anthropic API

Lumosel speaks the Anthropic Messages API. Any SDK or tool that works with Anthropic works with Lumosel — just change the base URL and use your key.

curl https://api.lumosel.vip/v1/messages \
  -H "x-api-key: YOUR_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "content-type: application/json" \
  -d '{
    "model": "claude-opus-4-8",
    "max_tokens": 1024,
    "messages": [{"role": "user", "content": "Hello, Claude"}]
  }'

# pip install anthropic
from anthropic import Anthropic

client = Anthropic(
    base_url="https://api.lumosel.vip",
    api_key="YOUR_API_KEY",
)

msg = client.messages.create(
    model="claude-opus-4-8",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello, Claude"}],
)
print(msg.content[0].text)

// npm install @anthropic-ai/sdk
import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  baseURL: "https://api.lumosel.vip",
  apiKey: "YOUR_API_KEY",
});

const msg = await client.messages.create({
  model: "claude-opus-4-8",
  max_tokens: 1024,
  messages: [{ role: "user", content: "Hello, Claude" }],
});
console.log(msg.content);
