Sonar Reasoning Pro costs $2.00 per 1M input tokens and $8.00 per 1M output tokens. Web search costs $0.005 per search. These are official prices as of October 18, 2026, charged per use to your prepaid balance. The console always shows the current price.
Sonar Reasoning Pro has a context window of 128K tokens (128,000 tokens).
Sonar Reasoning Pro supports image input (vision) and reasoning. It takes text and image input and returns text. The catalog does not list tool calling for it.
Send requests to https://api.oceantoken.ai/v1/chat/completions with the model ID perplexity/sonar-reasoning-pro 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.
