API Metering
Credits and per-call usage metering you can audit.
Metering is how Satelink counts and bills usage: every paid call is measured at a flat rate and drawn down from a prepaid balance, so spend is predictable and auditable per key.
Prepaid balance
Deposit once in USDT; every call draws down at the flat per-call rate.
Per-key accounting
Usage is attributed per key so you can see exactly where spend goes.
No surprise invoices
You spend only what you deposit — there is no post-paid overage bill.
