By using an API Gateway, we can
give each API Consumer their own
API Keys and track usage.

individually!
Usage-based
Pricing
Graduated
Price per unit increases with
higher usage
​
(e.g. first 1k = $0.01, next 10k =
$0.005)
01
Volume
One rate applies based on total
usage
​
(e.g. if you cross 100k calls, pay
$0.003 per call for all)
02
04
Credit Burndown / Wallet
Prepay with credits, deduct per
use
​
(Ideal for flexible, prepaid usage
models)
03
Usage-Based Pricing
(Advanced Models)
Flat Fee with Overage
Fixed base + per-unit cost
beyond quota
​
(e.g. $99/mo for 10k calls, then
$0.01 per extra call)
🎯Use usage-based pricing
when flexibility or scalability is key.

Quick demo

When a customer buys credits, they’re paying upfront.
But the company hasn’t delivered the full value yet — the
service is only delivered when the credits are used.
So, from an accounting perspective, the company is
holding “unearned” revenue.
