Yes. Existing OpenAI SDK code usually only needs its base_url and API key swapped. Chat Completions, model listing and streaming are the first compatibility priorities.
Model prices are listed on the Models catalog. Prices are per 1M tokens and distinguish input, output, cache-read and cache-write token types.
Currently prepaid balance with usage-based billing. You top up a balance, then pay for the models and tokens you actually use — no fixed plan required.
Generally, if a request fails due to a model-provider error or a gateway error, it is not billed as a successful request. The balance ledger and usage records in your console are authoritative.
Top-ups go through Stripe. You can pay by card (Visa, Mastercard, American Express) or Alipay. Your balance is always denominated in USD. A saved card can be reused for one-tap top-ups, while Alipay is a one-time method and can’t be saved. The minimum top-up amount is shown on the billing page in the console.
At checkout, Stripe may show the amount in your local currency (for example CNY) using a converted rate that includes a 2–4% conversion fee, so it can look higher than the day’s market rate — this applies to both card and Alipay. If you switch the currency selector to USD, you pay the original USD price and the conversion is left to your card’s issuing bank or your Alipay wallet — usually closer to the market rate, though a card may add a foreign-transaction fee. The cheaper option depends on your card, wallet and region, but choosing USD generally avoids the extra Stripe markup.
CrossModel does not use your request content to train models, nor share it with unrelated third parties. Production logs do not retain request bodies. To complete a call, we forward the necessary request content to the model provider you choose; that provider’s data-handling rules are governed by its own terms.
Yes. We provide setup notes for common tools — see the integration guides. Most tools only need an API base URL, an API key and a model ID.
Yes — SSE streaming, function calling / tool use, and vision / image input. Capabilities vary by model and endpoint, so refer to the labels in the Models catalog and the corresponding docs.
Email us at feedback@crossmodel.ai. Including the model ID, request time, error message or the model name you’d like added helps us investigate.
