About

Starwell aggregates official statistics from 29 government and international sources (World Bank, Eurostat, FRED, Statistics Canada, etc.) into a single REST API and MCP server, returning every value with a citation to its original source table. It targets AI agents that need verified numeric data instead of hallucinated figures, and offers a free tier alongside paid plans.

What it does

The homepage positions the product as a way to stop AI agents from guessing numbers, sourcing data from national and international statistics bodies and attaching provenance, a license and a citation to each returned value. It also computes cross-source comparisons on request, such as inflation across several countries.
