Talos in Anthropic SDK

Point the Anthropic SDK at Talos and call any model through the Messages API.

Format
Anthropic Messages
Base URL
https://api.gettalos.xyz
Models
Any OpenRouter id. See them all

Steps

  1. Set baseURL to https://api.gettalos.xyz and pass your Talos key.
  2. Use any OpenRouter model id as model, Claude or not.
  3. Tools, images, prompt caching and streaming work as they do with Anthropic.
client.ts
import Anthropic from "@anthropic-ai/sdk"; const client = new Anthropic({  baseURL: "https://api.gettalos.xyz",  apiKey: process.env.TALOS_API_KEY,}); const message = await client.messages.create({  model: "anthropic/claude-opus-5",  max_tokens: 1024,  messages: [{ role: "user", content: "Hello from Talos" }],});

Highlighted lines are the ones you add or change. Put your own key where it says sk-talos-….

Python

client.py
import anthropicimport os client = anthropic.Anthropic(    base_url="https://api.gettalos.xyz",    api_key=os.environ["TALOS_API_KEY"],) message = client.messages.create(    model="anthropic/claude-opus-5",    max_tokens=1024,    messages=[{"role": "user", "content": "Hello from Talos"}],)
