FAQ

How is billing calculated?

Based on real DeepSeek token pricing: input cache-hit $0.014/M, cache-miss $0.14/M, output $0.28/M (flash). Your budget decreases with each request.

What happens when my budget runs out?

HTTP 402 is returned and your key becomes exhausted. Buy a new package to continue.

Is there a rate limit?

Yes. 30 or 60 RPM per key depending on your plan. Exceeding returns HTTP 429.

Can I use the OpenAI Python SDK?

Yes. Set base_url to our endpoint and pass your gateway key. Zero code changes needed.
