# jesseahawkins.com > An open, dated record of the global AI buildout: AI data centers, the power they draw, chips, US jobs, AI models, AI vendors and AI rules. Each figure links its source. The data is free to read and reuse under the terms each dataset names, with no key and no sign-in. Cite the page a figure comes from. Each dataset has fixed, dated releases with a sha256, so a citation can name the exact release. Within version 1 of the data API, a dataset id, a field name and a field type never change. ## Machine access - [MCP endpoint](https://jesseahawkins.com/data/mcp): Model Context Protocol over Streamable HTTP.
