OpenAI API — Pertanyaan yang Sering Diajukan

Which GPT models are available?

Currently available: gpt-5.4, gpt-5.5 — the latest GPT family with multimodal vision, code generation and data analysis, all through one key.

How is it billed? Is there a minimum?

Billed per token (input + output) — see the price table above. Pay-as-you-go via Alipay, WeChat Pay, USDT and credit card, from $1.

Is it OpenAI-compatible? Does it work with Cursor and Codex?

Yes — it is the OpenAI API, so Cursor, Codex and any OpenAI SDK work out of the box; just point the base URL and key at APIMaster.

Is my data safe?

Yes. Your API data is not stored or used for training, and all requests are sent over encrypted connections.

Why is it cheaper than OpenAI?

We aggregate volume across channels and bill per token with no minimums, so the effective price lands well below OpenAI's list price.
