Call the GPT API

Any OpenAI-compatible SDK works: set the base URL to https://api.oceantoken.ai/v1, use your OceanToken key and the model id as written.

Python
from openai import OpenAI
# Your API Key from the OceanToken console
client = OpenAI(base_url="https://api.oceantoken.ai/v1",
                api_key="YOUR_API_KEY")
reply = client.chat.completions.create(
    model="openai/gpt-6-sol",
    messages=[{"role": "user", "content": "Hello"}])
print(reply.choices[0].message.content)
