Frequently asked developer questions
Everything about connecting, architecture, billing, and privacy
Why is this cheaper than wiring up each AI API myself?
You get a single balance, a single API key, and one OpenAI-compatible request format for Claude, GPT and Gemini. No minimum deposit at each maker separately, no currency conversions.
Do you store my prompts or sensitive data?
We do not store the content of your prompts or of the answers — no table in our database has a column for them, and the gateway never writes request bodies to its logs. Two things are worth knowing rather than discovering later. When a provider refuses or fails a request we keep the first 400 characters of its error, and a refusal on content grounds sometimes repeats the phrase it objected to. And the provider you called does receive the request itself, because it cannot answer without it; the privacy policy links what each provider does with it.
How does Smart Fallback work?
If a provider has an outage or answers with an error, the gateway retries the same model through another route on its own — a different cloud account, or the key we bought from the model's maker. The client sees one answer, not a failure.
Is your gateway compatible with Cursor, Cline, OpenHands, and LangChain?
Yes. Our gateway speaks the OpenAI chat format (`/v1/chat/completions`), so all you need to do is point the `baseURL` at `https://api.flintbeam.com/v1` and pick any model. Code written against the older `https://flintbeam.com/v1` keeps working. Images, speech in both directions and embeddings have their own endpoints too: `/v1/images/generations`, `/v1/audio/transcriptions`, `/v1/audio/speech` and `/v1/embeddings`. There is no fine-tuning and no Responses API.
What payment methods do you support?
Bank cards through Stripe — Visa, Mastercard and Apple Pay — and cryptocurrency: USDT (TRC-20 and ERC-20), USDC, BTC and ETH. Both are credited automatically, and the exact list of coins and networks is the one shown at checkout.
