Send requests to https://api.oceantoken.ai/v1/chat/completions with the model ID nvidia/nemotron-3-super-120b-a12b:free and your OceanToken API key. The API is OpenAI-compatible, so an OpenAI SDK needs only the base URL https://api.oceantoken.ai/v1 and your key. The Responses API and the Anthropic Messages API (/v1/messages) work too. The same OceanToken API key works for every model your account can use. Full reference: docs.oceantoken.ai.
OceanToken is prepaid. Open Credits in the console, choose an amount and pay by card on Stripe's hosted checkout page (Link works too; Alipay and WeChat Pay are not available). Each top-up is between $10 and $100,000, and your balance updates a few seconds after payment. Have a trial code? Redeem it on the same page.
Purchased credits are valid for 12 months from the date of purchase. Credits from trial codes, promotions or gifts may have a shorter validity. All purchases are final and non-refundable, except where the law requires a refund. Section 6 of the Terms of Service has the details.
Not if the request never ran: a request refused for an insufficient balance or by a safety check, or one whose provider fails before returning any output, is not charged. A video job that fails releases the amount it held. If a request breaks off after the model has started producing output, for example a stream cut off part-way, you pay for the tokens that were processed and generated for it.
There are two ways to buy. Pay-as-you-go is self-serve: sign up, add prepaid credits and use every model in the catalog at its official price. Enterprise customers get agreement pricing based on expected usage: email support@oceantoken.ai.
