Frequently asked questions
How much does GPT 6 Astra cost?
GPT 6 Astra starts at $2.14 per 1M input tokens through the API Stock API. You pay per use from a single prepaid balance — there is no subscription — and the final price scales with parameters such as resolution or duration.
How do I call the GPT 6 Astra API?
Send a POST request to https://api.api-stock.com/api/v1/chat/completions with your API key and the model "gpt-6-astra", using the openai-compatible request format shown in the quick start above.
What happens if a GPT 6 Astra request fails?
API Stock automatically retries the request on a reserve provider. If every provider fails, the charge is refunded to your balance.
Can I use GPT 6 Astra with the same API key as other models?
Yes. Every model on API Stock — video, image, music and chat — shares one API key and one prepaid balance, so you can switch to GPT 6 Astra without new credentials.
