Point any OpenAI-compatible tool at https://api.affordableai.eu/v1. One URL change. Everything else stays the same.

OpenAI SDK

Reasoning / Thinking

Reasoning is inline by default — the model thinks through problems in the response text. This is fast and works with all tools.

For Claude Code and tools that expect separate reasoning with reasoning_content, add "reasoning_effort": "low" to your request:

curl -X POST https://api.affordableai.eu/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model":"deepseek-ai/DeepSeek-V4-Flash",
  "messages":[{"role":"user","content":"What is 17 * 24?"}],
  "reasoning_effort":"low"
}'

Tool Calling / Function Calling

Standard OpenAI function calling works. The model emits tool calls and our gateway preserves them across multi-turn conversations so your agent sessions stay fast.

tools = [{
    "type": "function",
    "function": {
        "name": "get_weather",
        "parameters": {"city": {"type": "string"}}
    }
}]
response = client.chat.completions.create(
    model="deepseek-ai/DeepSeek-V4-Flash",
    messages=[{"role": "user", "content": "Weather in Berlin?"}],
    tools=tools,
)
