OpenAI-Compatible API

from openai import OpenAI
client = OpenAI(
    api_key="sk-...",
    base_url="https://api.openai.com/v1"
)
Python — OpenAI SDK After
from openai import OpenAI
client = OpenAI(
    api_key="sk-...",

Frequently Asked Questions

Are these models as good as GPT-5 or Claude?

On major benchmarks (MMLU, HumanEval, MATH), DeepSeek V4 and Qwen-3 match or exceed GPT-5 and Claude 4 in many categories. For most real-world use cases — chat, coding, writing, analysis — you won't notice a difference. And you'll pay 10x less.

Is the API really a drop-in replacement for OpenAI?

Standard chat completions: yes. Change api.openai.com to api.llmkey.cc and keep your existing code. We support streaming, function/tool calling, JSON mode, and multi-modal vision inputs. Some advanced features (Assistants API, TTS, Whisper) are not yet available.

Do you store or log my data?

No. API requests and responses pass through our proxy in real-time and are not stored or logged. We track token counts for billing only. Your prompts are never used for training, never sold, never retained after the request completes.

How do I pay?

All billing is in USD via credit/debit card, processed securely by Paddle (our Merchant of Record). You'll see "Paddle" or "LLMKey" on your statement. VAT/GST handled automatically for most countries.

What about latency?

Our proxy runs in Hong Kong, adding typically 30-80ms overhead. For US/Europe users, total round-trip is 100-400ms. Streaming starts almost immediately. If you need lower latency, contact us about dedicated infrastructure.

Stop overpaying for AI.
