Anthropic-Compatible API: Call Claude with the OpenAI SDK
AAA TOKEN offers endpoints compatible with both Anthropic and OpenAI, so you can call Claude with the SDK you already know, without a separate Anthropic account.
AAA TOKEN is an Anthropic-compatible API service: call Claude through the OpenAI SDK chat completions interface, or keep using the Anthropic request format. Swap the base URL for the AAA TOKEN endpoint and add your key, and existing code and tools keep working. No Anthropic account is needed, and you top up with USDT or PayPal and pay by usage.

Why choose an Anthropic-compatible API
No Anthropic account needed
Skip the sign-up and regional hurdles. Register with AAA TOKEN and get a key that reaches Claude.
Works with the OpenAI SDK
Call Claude through the chat completions interface. Projects already using the OpenAI SDK only need a new base URL.
Anthropic format supported too
If you use the Anthropic SDK or Claude-based tools, you can keep your original request format.
Pay with USDT, billed by usage
Top up with USDT or PayPal and pay only for what you use, with no monthly minimum.
Start calling Claude in four steps
- Sign up and top up — Create an AAA TOKEN account and top up your balance with USDT or PayPal.
- Create an API key — Create an API key in your account dashboard and store it safely.
- Change the base URL — Set your SDK base URL to the AAA TOKEN /v1 endpoint and enter your key.
- Specify a Claude model — Put a Claude model name in the model parameter and send the request to get a response.
Python example
This example uses the OpenAI Python SDK and calls Claude by changing only the base URL and key.
from openai import OpenAI
client = OpenAI(
api_key="$AAA_TOKEN_API_KEY",
base_url="https://aaa.ashp.tw/v1",
)
resp = client.chat.completions.create(
model="claude-3-5-sonnet",
messages=[{"role": "user", "content": "Hello from AAA TOKEN"}],
)
print(resp.choices[0].message.content)
Is it right for you?
Good fit
Individual developers and teams who want one key for Claude, GPT and Gemini, pay with USDT or PayPal, and are billed only for actual usage.
Not a good fit
Organizations that need enterprise contracts, dedicated private deployments, or a direct agreement and official account with the model vendor.
