ExosAIStart with free AI API access
Create an ExosAI account on the Free plan, choose an eligible free model and use your available bonus credit. The same OpenAI-compatible endpoint also supports paid models when you add paid credit.
What free access includes
The Free plan has no plan fee. Available bonus credit pays for eligible free models only; it cannot pay for Claude, Grok or any other paid model unless that model is explicitly marked eligible in the catalog. Free access has account limits and depends on your remaining bonus balance and model availability.
See current plan allowances and model eligibility and prices before sending requests.

- Set your OpenAI SDK base URL to
https://api.exosai.tech/v1and use your ExosAI key.
from openai import OpenAI
client = OpenAI(base_url="https://api.exosai.tech/v1", api_key="YOUR_EXOSAI_KEY")
reply = client.chat.completions.create(
model="MODEL_ID_FROM_THE_CATALOG",

)
print(reply.choices[0].message.content)Use free models in your tools
Use the same API key and model ID in Cursor, Cline or Continue, or test prompts in the AI playground. Tool calls, image input and context size depend on the selected model; check its catalog entry.
When you need paid access
Top up paid credit on any plan to use paid models or compare Pro and Max for their included balances and higher limits. Paid and bonus balances are separate. Unknown token prices do not mean a model is free.
