Sell leftover API credits for cash.
Prepaid keys sit idle. tokensto.cash lists them on Surplus Intelligence. You earn per request; Surplus batches USDC to your wallet.
How selling API capacity works
You are offering inference through an API key, not transferring a credit balance or selling an account. Buyers pay for requests that run on your listed models. A listing earns only when it serves paid requests; listing a balance does not guarantee a buyer or a payout.
What a minimum price means
A 0.05× minimum allows a price as low as 5% of the provider model’s list price. It is a floor for inference pricing, not a promise to recover 5% of your remaining balance. Raise it if you want a smaller discount, and compare selling with using the credits yourself.
Before you list
Check that your provider and account terms allow the proposed use. Use a dedicated key, set a daily budget you are comfortable consuming, and check the balance and expiry in your provider dashboard. Pausing or deleting a listing does not extend the provider’s expiry date.
What this is
Connect a provider key with leftover prepaid credits. Surplus probes the key, stores it encrypted, and routes paid inference through it. tokensto.cash never keeps the key.
Autopilot pricing
Autopilot starts with a 0.05× minimum for prepaid credits, follows healthy trusted demand, and raises the price when the market permits. You can set a higher minimum at any time.
Questions
- Do I lose the leftover credits if nobody buys?
- Listing alone does not consume credits. Paid requests use your capacity, and the provider’s expiry rules still apply. You can pause or delete a listing.
- Can I sell only after my own apps are done?
- Yes. Set leftover hours on Start or in Settings, for example 11:00 PM to 8:00 AM. Listings stay off the book outside that window.
- Can I set a minimum price?
- Yes. The automatic minimum for prepaid credits is 0.05× list. You can raise it, and Autopilot will never price below it.
