Money is the experience of the business model behind an API, whether the currency is dollars from external customers or budget allocated to internal teams. Plans, pricing, rate limits, and billing all shape how consumers experience the value an API provides and what it costs them to use it. Even free and internal APIs have an economics that determines whether they are sustainable. I pay close attention to the money experience because it is where APIs either become sustainable operations or quietly die from neglect. When the business model is clear and fair, consumers can plan around it and providers can invest in the API's future. When it is opaque or punitive, even a technically excellent API will struggle to build a healthy ecosystem around it.

Policies
FinOps Cost Visibility
I require that the full cost of running an API is made visible through FinOps practices, so the people making decisions about an API can see what it actually costs to operate, not just what it earn...
Monetization Cost Attribution
I require that API usage and its costs can be attributed back to the team, application, or consumer that generated them, so the true cost of operating and consuming an API is visible rather than sm...

Monetization Plans Defined
I require that every API in production publishes its access plans as machine-readable definitions, so consumers can see the tiers, the limits, and the pricing without emailing a salesperson or gues...

APIs Have Clear Service Level Commitments
All production APIs must have defined service level agreements (SLAs) that specify uptime, availability, latency, and throughput commitments for each plan tier, providing consumers with the confide...
