Sell unused DeepSeek credit: check the balance and list it
To list an unused DeepSeek balance, run `npx uberllm sell --provider deepseek`. It reads your balance from DeepSeek’s own balance API, splits it into what you paid in and what DeepSeek granted you, and lists the models you choose only after you say yes. DeepSeek’s platform terms tell you not to share your API key with others, so ask DeepSeek before you list.
List it in one command
npx uberllm sell --provider deepseek
You are asked for your DeepSeek key. Typing is hidden, and the key goes only to DeepSeek at this point. After the check you choose the models and the price, and nothing is listed until you type yes. To check the key and stop there, add --check-only.
Prefer the browser? Open the seller form with DeepSeek chosen and paste the key there.
What the check shows
uberllm sell reads DeepSeek's balance endpoint (GET /user/balance). You see, in the currency of your account (CNY or USD):
- Balance: everything the key can spend now.
- of which paid in: what you topped up.
- of which granted (free) credit: credit DeepSeek gave you that has not expired.
DeepSeek also says whether the balance is enough for requests. If it is not, the command stops there, because an offer with no credit behind it fails its first test.
What DeepSeek's terms say
We read the DeepSeek Open Platform Terms of Service on 2026-11-13. Section 2.2 said "do not share or publicly disclose your API key with others", and that you answer for fees and losses caused by sharing a key. Listing a key on UberLLM gives us the key so buyers' requests can be served with it.
That reads to us as: ask DeepSeek first, and list only if they agree. Terms change, so read the current text yourself. If you list a key against your provider's terms, the provider can close your account, and we remove the offer.
Before you list
- Sell only what you paid in. Granted credit is free credit, and free or trial credit cannot be listed.
- DeepSeek names its models differently from us. You do not have to match them: we read DeepSeek's model list with your key and list only models that are the same as ours.
- Your balance may be in CNY. Buyers pay in USD and you are credited in USD.
- Stolen, leaked, shared, free-trial and evaluation keys cannot be listed.
After you list
Each model is tested with one small request on your key. Then we check that the offer serves the model it lists, and a person on our team approves it. We email you when it is live. Buyers pay your price, all of it is credited to you, and UberLLM takes no fee from your sales. Your own cost is what DeepSeek charges your key. The rules and the API are in the sellers doc.
