Can I offer both subscription and pay-per-use billing for my API?

Yes. Sertone supports both models simultaneously. API owners define subscription tiers and a pay-per-call fallback price. Consumers choose whichever billing model suits them.

How are API subscription payments handled?

When a consumer subscribes, they pay USDC upfront automatically. The API owner receives 95% immediately. The subscription token authorizes API calls for the plan duration without additional payments.

What happens when a subscription expires?

When a subscription expires, the consumer can renew or fall back to pay-per-use pricing. There is no service interruption — billing simply switches to per-call mode until they renew.

API Subscription Plans — Recurring Revenue

Consumer pays USDC for a subscription plan → receives token → makes unlimited calls within limits → owner earns 95% revenue

Why Subscriptions on Sertone?

Pay-per-use is great for occasional consumers, but high-volume users want predictable costs. Sertone lets API owners offer both models simultaneously: pay-per-call for light users, monthly or yearly subscriptions for power users.

Subscription plans are managed automatically. When a consumer subscribes, USDC is transferred upfront and the subscription period starts immediately. The consumer receives a token that authorizes unlimited API calls within their plan limits for the subscription duration.

For API owners, subscriptions mean recurring, predictable revenue. No invoice generation, no payment reminders, no churn management headaches. When the subscription expires, the consumer either renews or falls back to pay-per-use pricing.
