Anthropic

Overview

Anthropic builds the Claude family of AI models, known for strong instruction following, safety, and long-context performance. Floopy automatically translates OpenAI-format requests to the Anthropic Messages API, so no code changes are needed.

Supported Models

Setup

1. Go to Settings > Providers in the dashboard.
2. Click Add provider and select Anthropic.
3. Paste your Anthropic API key and click Save.

Usage

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.floopy.ai/v1",
  apiKey: process.env.FLOOPY_API_KEY,
});

const response = await client.chat.completions.create({
  model: "claude-sonnet-4-6",
  messages: [{ role: "user", content: "Explain quantum computing." }],
});

from openai import OpenAI

client = OpenAI(base_url="https://api.floopy.ai/v1", api_key=os.environ["FLOOPY_API_KEY"])

response = client.chat.completions.create(
    model="claude-sonnet-4-6",
    messages=[{"role": "user", "content": "Explain quantum computing."}],
)

curl https://api.floopy.ai/v1/chat/completions \
  -H "Authorization: Bearer $FLOOPY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "claude-sonnet-4-6", "messages": [{"role": "user", "content": "Explain quantum computing."}]}'

Provider-Specific Features

• Automatic format translation — Floopy converts OpenAI chat completion format to the Anthropic Messages API and back. System messages, tool use, and multi-turn conversations are all supported.
• Long context — All Claude models support 200K token context windows. Floopy passes the full context through without truncation.

Fallback

Route to OpenAI if Anthropic is unavailable:

curl https://api.floopy.ai/v1/chat/completions \
  -H "Authorization: Bearer $FLOOPY_API_KEY" \
  -H "x-floopy-fallback-provider: openai" \
  -H "x-floopy-fallback-model: gpt-4o" \
  -H "Content-Type: application/json" \
  -d '{"model": "claude-sonnet-4-6", "messages": [{"role": "user", "content": "Hello"}]}'
