Betteria for developers
Betteria shows a person how far they have moved against their own past self, inside their own country, after prices. These pages explain how to connect an AI assistant to it.

What Betteria publishes
- Reference data version 2026.4 measures 149 countries. For each one the site publishes the yearly income bands a reading places a person on, in that country's own currency, with the confidence its data was graded with.
- A reading lands in one of nine named shapes, grouped in three families by what happened to a person's ground after prices.
- The working is public: what is asked, how the two movements are measured, the sources and the limits.
Two rules that hold everywhere
- No number comes from a model
- Every figure is computed by code from public sources. An assistant connected to Betteria quotes those figures; it does not produce them.
- Your account, your approval
- MCP works only signed in with your Betteria account, after you approve the connection. You can disconnect any client at any time from Settings, under Connected apps.
