Clear numbers at every step.

Each measured usage increase is credited to your balance at your rate, with a ledger entry you can read.

Who can submit API credentials?
Submit credentials you own or have explicit authorization to supply. Check your provider’s terms and the channel’s eligibility before submitting. Never upload a key you found online or received without permission.
Which credentials can I submit?
Available formats depend on the channel you choose. The upload form supports a standalone API key, an HTTPS endpoint and key, an access key pair, or service account JSON when the selected channel permits it.
What does the published rate mean?
Each listed channel has one Api4sale.si rate in USDT per $1 of accepted usage. For example, compare rates in Pricing, then confirm the selected rate in Add key before submitting. The rate alone does not predict usage or what will be credited to your balance.
How do usage, earnings and balance differ?
Key monitor shows cumulative usage measured for your keys, in USD. Total credited earnings is the sum of positive USDT ledger entries. Current balance reflects ledger credits and debits. Available to cash out also subtracts pending reservations. Usage and the published rate do not automatically create ledger credits.
What happens after I submit a key?
An accepted submission gets a key reference and starts as pending. Allow about 10–15 minutes for initial verification and startup. That is an estimate. Open Key monitor and choose Refresh usage to check the latest status.
Why hasn’t usage updated yet?
Usage can take 2–4 hours to update. Measured is when usage was last collected. Refreshed is when Api4sale.si last checked. Refreshing checks for a newer reading and can still return the same measurement.
How do I request and track a cashout?
After your address is approved, open Cash out and enter an amount within your available balance. The portal reserves the amount while the request is pending. An administrator records payment after an external transfer, and the transfer reference appears in Cashout history. Rejection releases the reservation.

Start with one small test key and a small cashout. Larger amounts follow the same path.
